Any electrical equipment from the simplest of toys, household white goods, machinery and the most sophisticated computer system requires an appropriate power supply to provide it clean power for functioning.

Most power supplies use a range of components to condition the input power received from the grid to deliver the right voltage, current and power level needed. For higher power equipment, power resistors are used for many functions like inrush suppression, bleeders, crowbar protection, dummy loads etc.

The range of resistors used to make power supplies is vast and the choice of the designer depends on many factors. Almost all the resistors from our extensive range can be used in some power supply application.

A cross section of our resistors are included in the list given below which can be considered for use in power supplies.
