Product Overview
SC series ac AC/DC module,has the advantages of small size, high efficiency, effectively save cost and space.
Product’s Introduction
The SC250 series is an independently regulated single output converter that uses the industry standard quarter brick package size. The very high efficiency is a result of ENARGY CORP patented topology that uses synchronous rectification and an innovative construction design to minimize heat dissipation and allow extremely high power densities. The power dissipated by the converter is so low that a heat sink is not required, which saves cost, weight, height, and application effort. All of the power and control components are mounted to the multi-layer PCB substrate with highyield surface mount technology, resulting in a more reliable product.
