Test engineers turn to programmable power supplies when they need to apply power to their device under test (DUT). Sometimes, the DUT has a small amount of stored energy that needs to be removed ...

There are so many applications for power resistors that they cannot be easily tabulated. Discussed here are a few practical, useful applications that you will find interesting. First an image with ...

A perennial challenge in power-supply design is the safe and speedy discharge, or “dump,” at turn-off of the large amount of energy stored in the postrectification filter capacitors. This energy, CV 2 ...

TT electronics Welwyn Components has launched the WPYP range of flameproof wire-wound resistor with terminations designed for direct connection across the stud terminals of a large can electrolytic ...

Electrical engineering students are taught about magnetics and that energy is stored in an inductor when it is energized. This can be presented in a theoretical sense and may be applied to topics like ...

(click thumbnail)Fig. 1: A gang of high-voltage bleeder resistors.Last issue I encouraged you to inspect and clean transmitter capacitors. Through an inspection with a bright trouble lamp, you can ...
