Brief Introduction
DCDB-3 microcomputer DC power supply panel is a standard DC power supply system designed for users with different capacities. Using 7 inch touch screen monitoring system as the core, Chinese/English menu display, touch operation, multiple password permissions, man-machine interface friendly and rich, with simple operation, intelligent management, high efficiency and energy saving and remote control features. The system can be composed of monitoring module, rectifier module, buck module, battery inspection module, branch monitoring module and switch outputmodule. The input voltage is AC220V, AC380V, and the maximum output capacity is DC110V/1500Ah, DC220V/1000Ah. If the system needs to provide external flash signal, accident signal, warning signal, inverter power supply, DC24V or DC48V power supply and other functions can be selected and added according to user needs, and the external size can be customized.
Suitable for power plants, hydropower stations, all kinds of substations, switching-closing offices and other users using DC equipment, for electromagnetic operating mechanism, permanent magnet operating mechanism and spring energy storage operating mechanism and other types of circuit breakers, as well as secondary circuit instrumentation, control circuit, relay protection and accident lighting and other types of high and low voltage equipment to provide DC power supply.
