GZDW-2
Intelligent Wall Mounted DC Power Supply Device
The GZDW-2 Intelligent Wall-Mounted DC Power Supply Device is designed specifically for substations, switch stations, and end-user terminals. It is an intelligent, integrated wall-mounted power supply that utilizes parallel current-sharing technology to enable maintenance without power interruption. Suitable for industries such as mining, petrochemical, construction, and end-user terminals, it serves as the operational and control power source for high-voltage switches, relay protection, and automation devices, and can also function as a low-voltage backup power source. The system includes 4 lead-acid batteries and features battery activation, battery testing, overvoltage, and overcurrent protection.
