Collection:AC Power Supplies

AC power supplies are used for supplying alternating current (AC) power to loads. The input can either be alternating current or direct current. In many cases, the power provided by wall outlets (mains supply) and various power storage devices is incompatible with the power requirements of the load. An AC power supply solves this problem by translating and fine-tuning the AC power from the electrical source to the voltage, current, and frequency that the device needs. This is done by stepping up or stepping down the voltages, followed by filtering. Thus, the device is supplied with electrical power in a controlled manner.
