Summary

GZDW wall mounted DC power cabinet is a DC power supply system specially designed for various small capacity users. With LCD monitoring system as the core, Chinese menu display, key operation, multiple password permissions, friendly and rich man-machine interface, it has the characteristics of compact structure, wall mounted installation, simple operation, intelligent management, energy saving and remote control. The system can be composed of monitoring module, rectifier module, step-down module, battery inspection module, insulation monitoring module, etc. Input voltage AC220 V, output capacity dc110 V / 65 ah, DC220 V / 50 ah. If the system needs to use pt100v AC input or provide flash signal, accident signal, warning signal, DC24V or DC48V power supply and other functions for the outside, it can be added according to the user's needs, and the overall size can be customized.

It is suitable for power plants, hydropower stations, all kinds of substations, switching stations and other users using DC equipment. It provides opening and closing power supply for electromagnetic operating mechanism, permanent magnet operating mechanism, spring energy storage operating mechanism and other types of circuit breakers. It also provides DC power supply for instruments, control circuits, relay protection, emergency lighting and other high and low voltage equipment in the secondary circuit.
