The GZDW-100AH DC Power Cabinet is a floor-standing, intelligent DC power system designed for reliable backup and main power supply in substations, power plants, telecom base stations, and industrial facilities. It features a high-frequency switching rectifier with full digital control, delivering stable 220VDC output from 380VAC input. The cabinet integrates battery management with automatic charging modes (boost, float, equalize), comprehensive protection (overvoltage, undervoltage, overload, short circuit), and remote monitoring via RS485/Modbus. With a rated capacity of 100Ah, modular expandability up to 300A, and IP30 protection, it ensures continuous operation in harsh environments. Applications include control power, switchgear operation, emergency lighting, and communication equipment.
