For the uninitiated, a power source is a power source. You simply stick the plug into the wall and power the device that you need. But it isn’t as simple as that, and using the wrong output can damage whatever you are using.
This is why having access to a programmable power source can be necessary depending on the situation. Being able to adjust voltage, current, and frequency can be hugely valuable in a multitude of applications.
Also known as a PPS, a programmable power source is one that can be controlled through remote operation, digital interface (think GPIB or RS232), or through an analog input. Being able to control properties such as current, voltage, and frequency (in the case of output power supplies) can be crucial.
Each programmable power source includes voltage and current programming circuitry, a processor, a readback circuit for both current and voltage, and a current shunt. There are some that even have short circuit protection as well as overcurrent and overvoltage protection.
Finding the Right Unit
When looking for a PPS, it is important to have a variety of choices at your disposal. Being able to specify things such as output power and frequency, current output, and even the dimensions of the power source can all make an impact depending on what the application is. But at the end of the day, it comes down to having a reliable power source that will hold up against whatever usage you are throwing at it. For more information, please visit Amp-Line Corp.
