Intelligent Maintenance-free DC Power Supply Panel

Product Introduction:

This DC operating power supply panel adopts modular IGBT inverter soft switch AC-DC, DC-AC or AC-DC rectifier charging. This maintenance-free DC power supply's charging module has N+1 redundancy hot backups. Under the control of microcomputer intelligent monitor module, the charging module can achieve maintenance-free storage battery's charging. This module has constant-current limit voltage and constant-voltage limit current charging control functions. DC operating power supply panel owns quick output response speed and high control accuracy. This maintenance-free DC power supply system consists of charging module, intelligent monitoring module, AC power distribution module, bus voltage regulating module, bus insulation monitoring module, signal power supply control circuit module, operation power supply control circuit module and maintenance-free batteries. Intelligent maintenance-free DC power supply panel can provide uninterrupted switching DC power supply of 6KV, 10KV, 35KV, 110KV, 220KV grade high voltage switch. This DC operating power supply panel can also supply uninterrupted control bus power supply for control system. It can be widely used as uninterrupted DC operation power supply in transformer substation and power plant of power transmission and distribution, and in self-provided power plant and transformer station of mine enterprises.
