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 where long time power disconnection is not allowed and ceaseless power supply is needed.
Full automatic power supply changeover system: It is equipped with three 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 order 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 remote regulating. Remote vision can be achieved through matching intelligent power distribution system.
Safe and reliable, and have fire control linkage function: When fire disater 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.
