1. General Introduction

ZZG13 series high frequency switching rectifier module is manufactured by our company on the basis of many years experience in the field of developing and manufacturing power supplies, which is specially used for the dc operating power supply in electric power system. The module can be used in a single module way or in way of many paralleled modules to supply dc load and meanwhile to charge the batteries. The module can be widely used in power plants and substations and also it can be used as the dc voltage constant or current constant power sources.
