Summary

GZDW microcomputer DC power supply panel is a standard DC power supply system specially designed for users with different capacities. It adopts 5-inch touch screen monitoring system as the core, Chinese menu display, touch operation, multiple password permissions, friendly and rich man-machine interface, 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 and switching value monitoring module. The input voltage is AC220V and AC380V, and the output capacity is dc110v / 1500ah and dc220v / 1000ah. If the system needs to provide flash signal, accident signal, warning signal, inverter power supply, DC24 V or dc48 V power supply and other functions for the outside, it can be added according to the user's needs, and the external dimensions 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 on-off and on-off power supply for circuit breakers of electromagnetic operating mechanism, permanent magnet operating mechanism and spring energy storage operating mechanism, as well as DC power supply for instruments, control circuits, relay protection and emergency lighting in secondary circuit.
