Ensure un interruptible service of critical electric power When overvoltage， under-voltage or phase break occur to a power supply it will automatically switch over to another power supply or start the electric generator. It is mainly used in hospital, shopping mall, bank, hotel, high buildings and fire control whe「e long time power disconnection is not allowed and ceaseless power supply is needed.
Full automatic power supply changeover system It is equipped with th「ee changeover methods including automatic connection and automatic changeover, automatic connection and non-automatic changeover, reserve for each other., and two service modes including power grid power grid, power grid-electricity generator, in O「der to satisfy different power changeoverrequirement.
Intelligent It has communication interface with built in RS485, and has two kinds of communication agreement including MODBUS RUS and electric meter 1997, which can realize real time data upload, distance data configuration and condition monitor, and can achieve the function of telecommand, telemetering， remote control, and 「emote regulating. Remote vision can be achieved through matching intelligent power distribution system.
Safe and reliable, and have fire control linkage function When fire di日ster occurs to no fire control load, fire protection control center can send signal to intelligent controller, cut off double powersupply, ensure firedisaster load to break.
