>Product Overview

GZDW series microcomputer-controlled DC panel is suitable for substations, power plants, industrial and mining enterprises, electrified railways and high-rise buildings of different voltage levels, and can be used as high-voltage switchgear, relay protection, automatic device operation power supply and control power supply. The system adopts the integrated design idea, which is composed of monitoring module, rectifier module, insulation monitoring module, battery inspection module, switching quantity monitoring module, step-down module, etc., and has the characteristics of technology, reasonable configuration, intelligent measurement and control, and easy operation. It can communicate with the host computer and easily realize the four remote functions of "telemetry, remote control, remote signaling and remote adjustment", and is an unattended DC power supply equipment.
