The universal switch power supply adopts power semiconductor as the switching element. The output voltage is adjusted by making and breaking the switch periodically and control the time ratio of off to on of the switch elements. Meanwhile, it has over-current and over-voltage protection.

It has the advantages of small output wave, high efficiency, small volume, light weight, and elegant appearance.
