DC Power Supply System

GZDW Series

GZDW series DC power supply systems are primarily composed of high-frequency switching power modules, monitoring units, maintenance-free batteries, and feeder circuits. The system offers numerous advantages, including lightweight design, compact footprint, high efficiency, advanced intelligence, easy operation and maintenance, and high reliability. It is mainly applied in small-to-medium-sized power plants, hydropower stations, various substations, switching stations, and industries such as petrochemicals and metallurgy. As a critical piece of equipment for ensuring the safe operation of power grids and power plants, it provides DC power for circuit breaker opening and closing, as well as for various high-and-low-voltage equipment within secondary circuits, including instrumentation, control loops, relay protection, and emergency lighting.
