DC-DC power supply operating system screen is short. GM called intelligent maintenance-free DC power panel, called DC-screen, universal model for GZDW, while the DC panel is used to supply such a DC power supply. Simply put, DC panel is to provide a stable DC power supply equipment. (When the input is 380V power directly into 220V, when the input (mains and standby power) are not entered directly into a battery-powered - DC 220V: in fact it can be said is an industry dedicated emergency power supply) . Power plants and substations in the power supply operation today are used in DC power, it controls the load and power load and DC load to provide emergency lighting power, is the contemporary power system control, basic protection. DC panel consists of cross-distribution unit, charging module unit, diode chain unit, DC feed unit, power distribution monitoring unit, the monitoring module unit and insulation monitoring unit. Mainly used in power systems for small and medium power plants, hydropower stations, various substations, and other user-DC devices (such as petrochemical, mining, railways, etc.), applicable to switches open and close, and the secondary circuit of instruments, meters, following electrical protection and fault lighting and other occasions. DC panel Features: ◇ front glass doors of the cabinet as a whole, followed by a double door, elegant appearance; ◇ cabinet design for easy equipment installation, maintenance, repair and operation of the operation; ◇ cabinet number and the number of modules, feeder circuits number, type and capacity of the battery, the DC voltage level and other factors
