Industrial Control Panel Basics
https://www.rspsupply.com/c-1618-enclosures.aspx What is a control panel and why do we use them? First let’s talk about the basic layout of a panel and why we locate items where we do. - Many different ways to layout a panel - Airflow - Safety - Field wiring, where do wires enter the panel? Let’s go over all the components in the panel and what their intended purpose is. - Enclosure and Backplate - Main Circuit Breaker - Branch Circuit Breaker - Surge Suppressor - Protects against lighting and power surge - AC Power distribution - Power Supply - Converts one form of power to another - DC Power Distribution - Ethernet Switch - It allows several different devices within the cabinet to communicate with one another - Radio - Industrial radio that is paired with a polyphaser (which protects the radio and internal panel hardware from lighting strikes) and an antenna ( to enable communication to other sites). Only used in cases where the panel cannot communicate locally via ethernet cable. - PLC (Programmable Logic Controller) - This is the brains of the operations. It sends and receives data from all the different inputs and outputs its connected to. It then interprets that data and communicates it into values that we can understand. - HMI (Human Machine Interface) - Allows us a way to view and interact with the data being collected by the PLC. Commonly mounted on the front of the panel. - IO - Analog vs Digital signals. Digital Inputs and Outputs - Relays - Why do we use relays for digital outs? Can be used for many other purposes. - Wire Duct and Dinrail

Power Supply Control Using 4 Different Sources for Continuous Power by KitsGuru.com | LGEE001
Auto supply switching (http://www.kitsguru.com/electrical-projects/auto-power-supply-control) is basically selection of supply from multiple available power sources automatically by using microcontroller concept that is to check the availability of the source and switching to that available source to ensure uninterrupted power supply to load. In case of the electrical appliance control using automation causes more safety. Auto supply switching is a prototype for the same which is auto change to other source when main supply fails without human interaction in this system we are designing an embedded circuit to control and ensure auto supply switching. In case all 4 phases are available, then the switching will be in the default phase. Four relays are there to control the switching. As it is not feasible to provide all 4 different sources of supply, one source with alternate switches are provided to get the same function. In this project we are having 4 switches which we consider as 4 different source of supply. When we press any of the switches it shows the absence of that particular source which is connected to microcontroller as input signals. Here we are using 8051 family microcontroller. The output of microcontroller is given to the ULN2803 this acts as a relay driver. The current phase working is displayed on LCD also.

12v Relay Trigger Using 5v Digital Signal : Tutorial 25
The advantage of relays is that it takes a relatively small amount of power to operate the relay coil, but the relay itself can be used to control motors, heaters, lamps or AC circuits which themselves can draw a lot more electrical power. The electro-mechanical relay is an output device (actuator) which come in a whole host of shapes, sizes and designs, and have many uses and applications in electronic circuits. But while electrical relays can be used to allow low power electronic or computer type circuits to switch relatively high currents or voltages both “ON” or “OFF”, some form of relay switch circuit is required to control it. The design and types of relay switching circuits is huge, but many small electronic projects use transistors and MOSFETs as their main switching device as the transistor can provide fast DC switching (ON-OFF) control of the relay coil from a variety of input sources so here is a small collection of some of the more common ways of switching relays. NPN Relay Switch Circuit A typical relay switch circuit has the coil driven by a NPN transistor switch, TR1 as shown depending on the input voltage level. When the Base voltage of the transistor is zero (or negative), the transistor is cut-off and acts as an open switch. In this condition no Collector current flows and the relay coil is de-energised because being current devices, if no current flows into the Base, then no current will flow through the relay coil. If a large enough positive current is now driven into the Base to saturate the NPN transistor, the current flowing from Base to Emitter (B to E) controls the larger relay coil current flowing through the transistor from the Collector to Emitter. For most bipolar switching transistors, the amount of relay coil current flowing into the Collector would be somewhere between 50 to 800 times that of the required Base current to drive the transistor into saturation. The current gain, or beta value ( β ) of the general purpose BC109 shown is typically about 290 at 2mA (Datasheet).

Christmas Lights and Their Control Signals
Ever wondered how twinkling LED lights are controlled? To show how it's done, I wrapped a set around my oscilloscope and probed the control signal while cycling through the different patterns on the power supply. A positive voltage powers the blue and green LEDs while a negative voltage activates the red and orange ones. By switching between positive and negative voltages really fast (about 300 Hz) it looks like all the lights are on at the same time. By varying the size of the pulses, the brightness of the lights can be varied as well. Most of the twinkling/flashing Christmas lights on the market at the moment are of a similar type. Mine has 4 colours and is connected to a controller by a 2 pin connector. The string of lights contains 10 sets of strands connected in series. Each strand contains 10 LEDs connected in parallel. The red and orange ones are connected with a polarity opposite to the blue and green ones. As LEDs only light up when a voltage with the right polarity is applied, different lights can be controlled by applying positive and negative voltages.

Differences Between Power Supplies, Inverters, and Transformers
In today’s video we are going to be looking at the differences between several pieces of hardware that often get confused even though they are intended for very different purposes. This hardware includes: power supplies, inverters, transformers and voltage converters. All of this hardware is intended to alter or change the type of power or voltage you might be using. The result you need will directly impact which type of hardware you may choose to use. However, it is very common for people to confuse the different types of hardware. Let’s discuss each type and what it is intended to do… so hopefully by the end of this video you will have a very clear understanding of each... and when you might want to use them. Let’s first start with power supplies. A power supply can have many different functions, but most of the time, the power supply use intended to take one type of power and convert it to another type of power. The most common example of this is a power supply that takes AC voltage and converts it to DC voltage. While it is very common to use power supplies in industrial applications, one very common place you will see a power supply used is for the gadgets you have around your home such as: your smartphone, laptop or tablet and many other devices we use on a daily basis. You may have noticed that most devices you have come with a power cord with a bulky block on the end of it. This block is where you will typically find the power supply. So most of your devices do not use AC power, which is the type of power being supplied to your home. These devices more commonly use some form or DC power. That little bulky block (or power supply) is what changes that AC voltage, to the correct DC voltage for your device. Power supplies can also be used for other purposes such as conditioning power (which is basically a way to clear the power of any interference or “noise” that may affect your electrical equipment. You also see power supplies that are used to convert one type of DC voltage to another type of DC voltage, however, in this case you may see them referred to as DC power converters… A DC power converter is a type of power supply. One last type of power supply we will talk about is referred to as a UPS, or uninterruptible power supply. The UPS often works in conjunction with a standard power supply... and is intended to continue to supply power to your load even when the input power is lost. It is able to do this because the it uses batteries to supply that power. A UPS is a great option when your electrical equipment is performing important tasks that need to be continued in the event of a power failure. Now let’s talk about inverters, an inverter works in a similar manner to the power supply with one major difference, instead of converting AC power to DC power… the inverter does the opposite. tI will change DC power to AC power. DC power is created by devices such as solar panels or batteries, but often we need AC power for the things we commonly use. For example, if you have solar panels on your roof, the power that is being created comes in the for of direct current (..or DC). But, in our homes most of the things that we need to power require alternating current (..or AC). So in order to convert the DC power that is generated by the solar panels... an inverter is used. Lastly, let’s talk about transformers. For more detailed information about how transformers work, please see our other video which we will link in the description below. Similar to a power converter that is used for changing only DC power… the transformer is intended to be used with AC power. More specifically, transformer converts one type of AC power to a different type of AC power. For example, your home commonly uses 120 volt AC. However, there are some electrical devices we use in and around our homes that need AC power, but cannot operate with 120VAC. So in this case a transformer is used. If you have an automatic sprinkling system, chances are the valves in that sprinkling system require 24 volts AC. To do this, a transformer converts 120VAC that is available in our home, to 24VAC so the sprinkler valves can operate properly. Transformers come in many different shapes and sizes. It is important to note, that transformers can both convert AC power up and down. So if a greater AC voltage is needed, a transformer will be used… and the same can be said when a lower AC voltage is needed. So let’s quickly recap…. Power supplies most commonly convert AC power to DC power. Power converters are used to change the voltage within the DC range only. ...and UPS’s are intended to continue to supply power in the event of a power failure and are often used with a regular power supply. Inverters are intended to change DC power, back to AC power. …and lastly, transformer are used to change one type of AC voltage, to another type of AC voltage.. Up or down.

Magnetic Amplifier
Magnetic AmplifierA magnetic amplifier is an electromagnetic device for amplifying electrical signals. It controls the saturation degree of a choke by means of small changes of current in the control winding that cause big alterations in the AC winding. A magnetic amplifier consists of a magnetic core and several windings. The magnetic core is built of thin insulated plates made of electric steel. The windings of the magnetic amplifier are situated on the magnetic core. Let's look at the operation principle of the magnetic amplifier in a single-phase E core choke. AC windings 2 and 4 are connected so that the alternating magnetic fluxes (fy and f2) they create in the middle core cancel each other. Winding number 3 is situated on the middle core of the magnetic core. It is connected to a DC power supply and is called the control winding. The AC windings are connected to the consumer's circuit. They are called the operating windings. The DC current in the circuit of the control winding is much weaker than the AC current on the AC windings connected to the consumer's circuit. This is why by using the low power on the control winding (the weak electric signal) we can control the power of the large AC currents in the consumer's circuit (the converted high power signal). Magnetic amplifiers are widely used thanks to the following advantages. They are highly durable and reliable, have a high amplification ratio and are easy to maintain. Magnetic amplifiers have low threshold of DC signal sensitivity (10-19-10-17 V) and can amplify powers ranging from 10 W to hundreds of kilowatts. They are always ready for operation. Several control signals can be added together at the input. Magnetic amplifiers have a high overload capacity, are fire and explosion resistant. Their characteristics remain stable while in-service.

There are 3 control signal and 3 status signals. Three control signals are RD, WR & ALE. #RD − This signal indicates that the selected IO or memory device is to be read and is ready for accepting data available on the data bus. #WR − This signal indicates that the data on the data bus is to be written into a selected memory or IO location. #ALE − It is a positive going pulse generated when a new operation is started by the microprocessor. When the pulse goes high, it indicates address. When the pulse goes down it indicates data. @(Three status signals are IO/M, S0 & S1.)@ #IO/M This signal is used to differentiate between IO and Memory operations, i.e. when it is high indicates IO operation and when it is low then it indicates memory operation. #S1 & S0 These signals are used to identify the type of current operation. #Power supply There are 2 power supply signals − VCC & VSS. VCC indicates +5v power supply and VSS indicates ground signal. #Clock signals There are 3 clock signals, i.e. X1, X2, CLK OUT. #X1, X2 − A crystal (RC, LC N/W) is connected at these two pins and is used to set frequency of the internal clock generator. This frequency is internally divided by 2. #CLK OUT − This signal is used as the system clock for devices connected with the microprocessor. Interrupts & externally initiated signals Interrupts are the signals generated by external devices to request the microprocessor to perform a task. There are 5 interrupt signals, i.e. TRAP, RST 7.5, RST 6.5, RST 5.5, and INTR. We will discuss interrupts in detail in interrupts section. #INTA − It is an interrupt acknowledgment signal. #RESET IN − This signal is used to reset the microprocessor by setting the program counter to zero. #RESET OUT − This signal is used to reset all the connected devices when the microprocessor is reset. #READY − This signal indicates that the device is ready to send or receive data. If READY is low, then the CPU has to wait for READY to go high. #HOLD − This signal indicates that another master is requesting the use of the address and data buses. #HLDA (HOLD Acknowledge) − It indicates that the CPU has received the HOLD request and it will relinquish the bus in the next clock cycle. HLDA is set to low after the HOLD signal is removed. *Serial I/O signals There are 2 serial signals, i.e. SID and SOD and these signals are used for serial communication. *SOD (Serial output data line) − The output SOD is set/reset as specified by the SIM instruction. *SID (Serial input data line) − The data on this line is loaded into accumulator whenever a RIM instruction is executed. _-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- thnks to :-https://www.tutorialspoint.com/microprocessor/microprocessor_8085_pin_configuration.htm Dont Forget to *SUBSCRIBE* plsss thanks give atleast *1LIKE* .

Electronic DC Load Design and Testing
I keep saying that I need to build a DC Load to test the Power Supply designs and after a few Switching regulators reviewd and still no DC Load I decided it was time to get one done So wanting to support atleast 30V and 5Amps with the ability to hook up my Agilent 33622A Waveform generator and use a standard 5V signal to apply noise and other control signals + an accurate measurement on the shunt I set about designing one. Of course loads of folks have done one on the internet so I was in good company but adding my own features would keep me on my toes for design. I also wanted it to be stable and possibly have active cooling which was not part of this test but I did find an old CPU heatsink with a fan attached that will become part of the final build So I used my Keithley PSU to provide the source for testing and threw a range of signals at it all with great sucess I also tested to see "How Low I could Go" and managed to get the DC Load happily sinking over an amp into a meager 250mV source voltage. I was happy so now I need to get it into a case. Anyway, I hope you enjoy the video, sorry its just over an hour but its all there, the design, the testing, the lot.

Practical troubleshooting of microprocessor and microcontroller circuits using oscilloscope. Step by step checking the healthiness of the microprocessor based circuit by analyzing the signals from the microprocessor, which includes the control signals, data signal and address signals. Explain Microprocessor vs microcontroller and memory interfacing This example is basic circuit with less number of IC’s but the same troubleshooting techniques can be implemented in bigger circuits. The troubleshooting approach with microcontroller circuit can be a bit different as we don’t have external address and data bus with microcontrollers but the power supply checks and clock signal plus if there is I2C signal output should be good indication of microcontroller healthiness.

UPS Basics: Uninterruptable Power Supplies
What is a UPS A UPS (or uninterruptible power supply) is an electrical device the provides emergency power to a load when the regular input power source is lost. Depending on the UPS, they can also supply protection against spikes in voltage (or surges), which assist in protecting the equipment that they are connected to. A common place you might see this in practice is with computers. A computer will be able to continue to run when we experience a power outage. They are not typically designed for use over long periods of time. They are intended to be used for short periods of time to provide critical backup power, until an alternative power source can be used. Why do we need UPS protection? First and foremost, they allow our electrical equipment to continue to stay running in the event of a power outage. This can be very important if we are relying on our electrical equipment for important tasks and can’t afford to lose power. Some examples of this might be: Keeping power on in a Control Cabinet to enable the critical operations that it may be responsible for. Allowing us to save critical data that might be in jeopardy if a sudden power failure were to occur. If they provide surge protection, it can protect electrical equipment from becoming damaged due to overvoltage or overcurrent. This can save a lot of money and time for a relatively small investment. They can act as a bridge while the backup generator is started and synchronized with the electrical system. Where and when should we use UPS’s? Anytime we need backup power This could be for our personal computer at home …or for critical control equipment found in a petrochemical plant. How do they work? Depending on the type of power supply selected, they can function a bit differently The first type of power supply we commonly see is a “Offline” or “Standby” UPS. In this type of UPS the protected equipment is being powered by normal utility power. When voltage drops below a certain level, the UPS with mechanically switch the connected equipment to the inverter located on the UPS. At which point the UPS will then begin providing power from the battery. The second type of UPS commonly found is an “Online” UPS In this type of UPS the connected equipment is constantly drawing power from the battery through the converter, so no switching is necessary. Utility power is then used to keep the battery charged at all time. This allows from seamless power during an outage and can better protect electrical equipment it is protecting. Keep in mind, that these are just two of the more common types of UPS’s that are typically used. However, there are several other types of UPS’s that can be found that provide various other functions. UPS Selection When selecting a UPS for your specific application make sure to properly size the UPS to enable proper protection for all connected equipment. This can be done by look at the total watts being used by all connected equipment and ensuring that the UPS is rated for at least that amount, preferably 20% more than what is needed. UPS’s can be used in both AC and DC applications, just pay attention to what is needed in your specific application and make sure to select they correct power type.

Electronics: Introduction to LC Oscillators circa 1974 US Air Force Training Film
Support this channel: https://www.patreon.com/jeffquitney more at: http://scitech.quickfound.net "In an LC oscillator circuit, the filter is a tuned circuit consisting of an inductor (L) and capacitor (C) connected together." US Air Force Training Film TVK 30-536 Electronics playlist: https://www.youtube.com/playlist?list=PLAA9B0175C3E15B47 Originally a public domain film from the US National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). https://en.wikipedia.org/wiki/Electronic_oscillator Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/ An electronic oscillator is an electronic circuit that produces a periodic, oscillating electronic signal, often a sine wave or a square wave. Oscillators convert direct current (DC) from a power supply to an alternating current signal. They are widely used in many electronic devices. Common examples of signals generated by oscillators include signals broadcast by radio and television transmitters, clock signals that regulate computers and quartz clocks, and the sounds produced by electronic beepers and video games. Oscillators are often characterized by the frequency of their output signal: A low-frequency oscillator (LFO) is an electronic oscillator that generates a frequency below ≈20 Hz. This term is typically used in the field of audio synthesizers, to distinguish it from an audio frequency oscillator. An audio oscillator produces frequencies in the audio range, about 16 Hz to 20 kHz. An RF oscillator produces signals in the radio frequency (RF) range of about 100 kHz to 100 GHz. Oscillators designed to produce a high-power AC output from a DC supply are usually called inverters. There are two main types of electronic oscillator: the linear or harmonic oscillator and the nonlinear or relaxation oscillator... Harmonic oscillator The harmonic, or linear, oscillator produces a sinusoidal output. There are two types: Feedback oscillator The most common form of linear oscillator is an electronic amplifier such as a transistor or op amp connected in a feedback loop with its output fed back into its input through a frequency selective electronic filter to provide positive feedback. When the power supply to the amplifier is first switched on, electronic noise in the circuit provides a signal to get oscillations started. The noise travels around the loop and is amplified and filtered until very quickly it becomes a sine wave at a single frequency. Feedback oscillator circuits can be classified according to the type of frequency selective filter they use in the feedback loop: In an RC oscillator circuit, the filter is a network of resistors and capacitors. RC oscillators are mostly used to generate lower frequencies, for example in the audio range. Common types of RC oscillator circuits are the phase shift oscillator and the Wien bridge oscillator. In an LC oscillator circuit, the filter is a tuned circuit (often called a tank circuit; the tuned circuit is a resonator) consisting of an inductor (L) and capacitor (C) connected together. Charge flows back and forth between the capacitor's plates through the inductor, so the tuned circuit can store electrical energy oscillating at its resonant frequency. There are small losses in the tank circuit, but the amplifier compensates for those losses and supplies the power for the output signal. LC oscillators are often used at radio frequencies, when a tunable frequency source is necessary, such as in signal generators, tunable radio transmitters and the local oscillators in radio receivers. Typical LC oscillator circuits are the Hartley, Colpitts and Clapp circuits. In a crystal oscillator circuit the filter is a piezoelectric crystal (commonly a quartz crystal). The crystal mechanically vibrates as a resonator, and its frequency of vibration determines the oscillation frequency. Crystals have very high Q-factor and also better temperature stability than tuned circuits, so crystal oscillators have much better frequency stability than LC or RC oscillators. Crystal oscillators are the most common type of linear oscillator, used to stabilize the frequency of most radio transmitters, and to generate the clock signal in computers and quartz clocks. Crystal oscillators often use the same circuits as LC oscillators, with the crystal replacing the tuned circuit; the Pierce oscillator circuit is also commonly used. Quartz crystals are generally limited to frequencies of 30 MHz or below. Other types of resonator, dielectric resonators and surface acoustic wave (SAW) devices, are used to control higher frequency oscillators, up into the microwave range...

water level controller | irrigation control system
The main components in this project are MAX II CPLD chip, sensors; motor, seven segment display and power supply. The sensors sense the presence of level or water and give indication to the CPLD. The CPLD produces the control signals to drive the motor according to the indication provided by the sensor. If there is no water (zero level) then CPLD gives control signal to start the motor and if there is sufficient water in then the CPLD gives a control signal to stop the motor. And also the CPLD enables the display and displayed the water level on the seven segments. Hence the level of water in a field can be automatically controlled.

Transistor Switch
Transistor SwitchTransistor switch is used for switching load circuits under the influence of external control signals. A transistor switch can stay in one of its static modes. The transistor is closed in a cutoff mode. In a saturation mode the transistor is open and saturated. Electronic switches are based on the operating principle of bipolar transistors. When there is no voltage in relation to the emitter at the transistor base then the transistor is closed. The current does not pass through it. A maximal signal, i.e. all supply voltage, is in the collector. When an electric signal is supplied to the transistor base then it opens, and a "collector-emitter" current appears. Voltage across the collector resistance drops. Then collector voltage drops. The output voltage drops correspondingly to a low level.Let's take a simple circuit of a transistor switch based on a bipolar transistor. We use КТ817 transistor - a collector power resistor is 1 kOhm, and 270 ohm resistor on the input. There is full voltage in the on-state... When the signal is supplied to the input, i.e. voltage, then voltage across the transistor collector is limited to the minimum...Transistor switches can also be based on field-effect transistors. Their operational principle is similar to that of electronic switches on bipolar transistors. Digital switches on field-effect transistors consume lesser control current. They provide a galvanic isolation of input and output circuits. However, their performance is slower as compared to bipolar transistors.Here is an example of using a field-effect transistor as an electronic switch. We use KP103 transistor. We may use a resistor from 10 to 100 kOhm...Transistor switches are used in various radio-electronic appliances, analog and digital signal switches, automation and monitoring systems, automatic equipment control systems, home radio and TV appliances, as well as in many other devices.

Why Do We Use AC or DC Power?
In today’s video we are going to discuss the two differents types of power we use every day in all sorts of electrical applications: AC power and DC power. More specifically, we want to talk about why we use AC or DC power in various applications. In many cases, you may know you need DC power for your specific scenario, or maybe a transformer to change to the voltage needed for your situation, but why are these changes necessary? Our hope is that by the end of this video, you have a better understanding of why we use components such as: Transformers, power supplies and power converters in so many of our electrical systems today. Let’s first discuss the basic differences between AC power and DC power. Electrical current is the flow of charged particles, or specifically in the case of AC and DC, the flow of electrons. The main difference between AC and DC power is the actual direction of the electron flow. DC power sees current moving in one direction and is constant. To better illustrate the constant nature of DC power,you can look at a graph, DC power will look like a straight line moving from left to right. AC power on the other hand, changes constantly over time. In this case, current can can flow in both a positive and negative direction. On a graph, this current flow looks like a sine wave, going up and down, alternating between a positive and negative flow. Hence the name Alternating Current. (Example) So let’s talk more about AC power and why it is used where it is. When power is generated, in almost all cases, it is generated in the form of AC power. Which is one of the reasons why it has become the more predominant form of power used today. We have the ability to transmit AC power at very high voltages and lower current levels over long distances This make it easy to take power that is being generated and send it to locations all over the world. The voltage levels generated with AC power can be easily changed up or down with the help of a transformer (which is a relatively inexpensive and mechanically simple device). https://www.rspsupply.com/c-3732-transformers.aspx With the ability to change the voltage levels, we can easily scale the amount of power that is needed in different applications. For example… The power that is provided to our homes comes in the form of AC power. Typically between 120 and 240 volts. Devices that can be used with AC power are not affected by the alternating characteristics of this form of power. Some common examples are: lightbulbs, many types of heating elements, AC motors, etc. However, some electrical devices are affected by this alternating current, in which case, a different type of power is needed. DC power. Because DC power is more difficult to generate, and because it is more difficult and expensive to convert AC power to DC power, it is not commonly used as the main power source for most applications. However, it is widely used in many different scenarios and converted when necessary. It is common to see DC power being used in more complex electrical circuits. More specifically, DC power will be used when electrical components require some type of microchip.. or processor. The nature of these microchips do not allow them to function with current that alternates back and forth from positive to negative. They need a constant, steady voltage source that DC power can provide. This is why the more “intelligent” electrical equipment that you have is typically being supplied with DC power. Even in devices such as computers and Televisions, that are being supplied AC power... they are actually using DC power. These devices convert AC power to DC for the components in that device that cannot operate with AC power. DC power is also used in many other applications such as charging batteries (which supply DC power), many lower voltage applications and DC motors. So while more difficult to generate or convert, DC power is widely used, especially in more complex electrical circuitry... where it is an absolute necessity. As you will commonly see, both forms of power will be used simultaneously in many different applications. For example, in an industrial control cabinet, you will typically see AC power being supplied, which will power some of the components within the panel… specifically components that are not affected by the alternating characteristics of AC power. You will then see that AC power being converted to DC power for the devices that are more complex and have some type of microchip or processor that requires DC power function properly.

What is HDBaseT 5Play?
HDBaseT provides multiple AV signal transmission over single Cat5e/6/7 cable and is the ideal solution for multiple zone, longer distance audio visual connectivity in both professional and residential AV systems. The HowtoAV team looks at the full capabilities of HDBaseT technology and HDBaseT 5Play, which refers to the 5 key signal elements which full HDBaseT is capable of transmitting over a single Cat-X cable. • Full HD and Ultra HD video HDBaseT 5Play is capable of transmitting full uncompressed HD and UHD 4k video signals, including 3D signal support and all without latency. • Digital Audio HDBaseT supports transmission of all digital audio formats including Dolby Digital, Dolby True HD and DTS Master Audio • 100BaseT Ethernet The third element of 5Play is standard 100BaseT Ethernet – ideal in smart TV applications requiring internet access directly to the screen. • Control Signals 5Play also transmits a number of key control protocols including infrared and RS-232 to allow for AV system-wide control of multiple sources and display devices. • Power over Cable And finally, in at number 5, full HDBaseT will also transmit Power over Cable, allowing power from the HDBaseT transmitter to be sent via the CAT cable to power receivers at the display end of the system, without the need for a local power supply.

FRA PSU Output impedance
Here we use the CS1070 power amplifier to measure the output impedance of a working power supply. The CS1070 internal 1 ohm source resistor is used as Rref, and acts as a current source. We assume the impedances measured are small compared to the 1 Ohm. The FRA control page sets the sink current to bias the power supply, and also the signal current. These can total up to 1 A.
