Product Introduction

GZDW series microcomputer-controlled DC panel is applicable to substations, power plants, industrial and mining enterprises, electrified railways, high-rise buildings and other fields with different voltage levels, and can be used as the operation power supply and control power supply for high-voltage switches, relay protection and automatic devices. The system adopts the integrated design idea, and is composed of monitoring module, rectification module, insulation monitoring module, battery patrol module, switching value monitoring module, step-down module, etc. It is characterized by technology, reasonable configuration, intelligent measurement and control, and easy operation. It can communicate with the host computer and conveniently realize the four remote functions of "telemetry, remote control, remote signaling and remote adjustment". It is an unattended DC power supply device.
