Intelligent high frequency switch wall style power supply

Wall style power supply is specially designed for small-capacity systems such as small-sized switch stations and small substations. The system adopts integrated design philosophy, and consists of rectifying modular, monitoring modular, voltage reduction unit, power distribution unit and battery cabinet. The monitoring modular adopts LCD Chinese menu for display and has perfect functions for system monitoring and battery intelligent management and boasts interfaces for remote control of signals, monitoring, signal and adjustment. It has communication ports of RS232 and RS485, and provides three communication protocols such as RTU, CDT, MODBUS.
