GZDW microcomputer-based DC screen

The GZDW series microcomputer-based DC screen is suitable for substations, power plants, industrial and mining enterprises, electrified railways, high-rise buildings, and other fields with different voltage levels. It can serve as the operational and control power supply for high-voltage switches, relay protection, and automation devices. The system adopts an integrated design concept, consisting of a monitoring module, rectifier module, insulation monitoring module, battery inspection module, switch quantity monitoring module, and voltage reduction module. It features specialized technology, reasonable configuration, intelligent measurement and control, and easy operation. The system can communicate with upper-level machines, enabling the convenient implementation of “remote measurement, remote control, remote signaling, and remote adjustment” (four remote functions), making it an ideal DC power supply device for unattended operations.
