Breakthrough from 'Interference Source' to 'Pure Reference' The non-partial discharge variable frequency power supply creates ...

This variable power supply is using 7805, 7809, 7812 or 7815 voltage regulators, where the last 2 digits represents the maximum output voltage of the IC. This circuit offers excellent ripple rejection ...

A benchtop power supply is a key thing to have for any aspiring electronics hacker. While you can always buy one, plenty of us have old computer PSUs lying around that could do a fine job themselves. ...

Once upon a time, building yourself a power supply required sourcing all manner of components, from transformers to transistors, knobs, and indicators. These days, everything’s a bit more integrated ...

Delta has expanded its PMR Series panel mount power supply with the new PMR-1K0W model, delivering up to 1,008W of reliable output power and an efficiency of up to 94%. With active current sharing, it ...

TDK has announced the addition of a 48V, 83.3A 4kW output power supply to TDK-Lambda’s TPS series. The TPS4000-48 operates from an industrial three-phase input. It can automatically run from 400, 440, ...

Utility power plant generators are usually designed for a power factor (PF) of .8 to .9. If demand-side PF is lower than the designed PF, the generator current will rise above the equipment's rated ...

Low-dropout (LDO) linear regulators have been widely used in noise-sensitive applications for decades. Nevertheless, noise requirements have become tougher to meet as the latest precision sensors, ...
