GZBW1 Series High Frequency Switching DC Power Cubicle With Computer Supervising And Controlling

Product Overview

The GZBW1 series High Frequency Switching DC Power Cubicle with computer supervising and controlling (call the DCPC as follows)is of an ideal product for using instead of a traditional phase-controlling SCR (silicon controlled rectifier) system. Which conquers many bugs from old SCR, such as heavy harmonic pollution, lower power factor, noise, less control accuracy for voltage and current steadying and need of back up charger etc..

That the DCPC adopts a high frequency switching charger, to be of a module structure and with N+1 hot backup, having the charact-eristics of on-line replacing and hot plug-in / pull-out, increases the reliability of system consumedly and reduces its investment.

The DCPC applies the intelligence supervisory equipment with LCD display and clearly operation menu and various communication methods. Using the intelligence supervisory equipment, the param-eters of the charging module, such as turn-on, turnoff, and constant current charging or floating charging can be setting or changing even the modifying right of setting. It also can be connected to upstream computer through a modem to perform the telecommuni-cating, remote measuring, remote controlling and adjusting, etc..

The DCPC can be mainly used in power substations, small or midsize power plants, the power transfer and distribution equipment of industrial or mineral enterprises and highrise buildings as a DCUPS power supply for relays, mechanism of circuit breaks, auto-device and telecommunication, even for illuminate and accident load under trouble of power supply.

The DCPC matches completely following standards:DL/T 459-2000 "Specification of DC supply cabinets in power system", (Chinese State Power Company)JB/T5777.4-2000 " The general specification and safety requirements for DC power supply equipment of the power system",etc.

The input voltage of the DCPC is 380V(3 phases) or 220V(singlephase) usually. The input can be single line or cluble lines. The back-up input can be connected into DCPC in double lines input system, the back-up input will therefore turn-on automatically if the main input loss.
