Most electrical engineers believe they have a good understanding of power supplies because they are relatively simple, single-function DC devices designed to output controlled voltages. However, there ...

The power supply on a computer transforms the alternating current from the wall outlet into a direct current flow that the computer's components can use. Testing the DC voltage output of the power ...

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 ...

No electricity provider in the world can guarantee an electrical supply that is free from voltage and frequency variations. The possibility of faults occurring in user installations or in the public ...

The most important thing to keep in mind when operating the server yourself is the power supply. Even if applications and networks are running normally, it does not make sense to power down essential ...

Here at eTeknix, we take our PSU reviews very seriously! I have always considered the power supply to be the most important part of a PC, although it does not have a very glamorous job like a graphics ...

We can often find useful or interesting things in old items. Some items can become invaluable under the right circumstances! In this post, I am talking about an older adjustable step-up dc power ...

We recently noticed a very cool-looking series of power supply modules on a few of the Chinese deal web sites. Depending on the model, they provide a digitally-controlled voltage with metering. You ...

ActionPower has released a modular programmable ac and dc power supply and load, aimed at testing photovoltaic micro-inverters. Helion, as it will be called, fits a 3U rack slot and designed to work ...
