Every automated test system that tests electronic circuit boards, modules or equipment needs one or more DC power supplies. Specifying the right supply involves more than just finding one that can ...

Many power supply alarm signals, such as AC Fail, DC Good, etc., utilize optocouplers or optical isolators as a means of transferring alarm signals from the power supply to the end-users equipment ...

Most medium to high power AC-DC power supplies and some DC-DC converters include “Remote Sense” connection points (+ and – Sense) that are used to tightly regulate the supply’s output voltage at the ...

How accuracy is defined in DC programmable power supplies How and why the power supply experiences voltage output errors How to wire test leads and sense leads for accurate measurements When testing ...

In a previous article, I wrote about generating negative voltages via a standard unipolar dc power supply outfitted with polarity-reversal relays (see “Turn Positive Voltages Negative With Relays”).

You may have seen the Ruideng range of programmable power supply modules from China: small and relatively inexpensive switch-mode buck converters, with microprocessor control and a front panel ...

Listen to advice from some corners of the internet, and it can sound like not buying the most efficient power supply possible will cause your PC to blow up. That’s simply not true, and you can spend ...
