Integrated Power Supply System

Hebei Yinhua Electric Co., Ltd. has designed and produced an intelligent high-frequency DC power screen for electric power systems, available in multiple models and specifications ranging from 800AH, 1000AH, 1200AH to 2500AH, meeting the DC power supply requirements of large, medium, and small power plants, substations, and distribution rooms. Its main performance features include stable operation, strong anti-interference capability, low ripple coefficient, and high technical precision. Additionally, it is equipped with comprehensive protection functions; adjustment and setting are intuitive and convenient, with dual AC inputs for enhanced reliability. It provides RS485 and RS232 communication interface options and supports CDT and MODBUS communication protocols. It fulfills the "four remote" functions of the DC power supply system, enabling unattended operation of substations.
