Product Overview

These DC-DC converter modules use advanced power processing, control and packaging technologies to provide the performance, flexibility, reliability and cost effectiveness of a mature power component. High frequency Active Clamp switching provides high power density with low noise and high efficiency.

 

Product’s Introduction

The ZG series is an independently regulated single output converter that uses the industry nonstandard 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.
