1.Ensure un-interruptible service of critical electric power When overvoltage, under-voltage or phase failure occur to a power supply, it willautomatically switch over to another power supply or start the electric generator.It is mainly used in hospital, shopping mall, bank, hotel, high buildings and firecontrol where long time power disconnection is not allowed and ceaseless powersupply is needed.

2.Full automatic power supply changeover system It is equipped with three changeover methods including self-throwing and self- reset (power network to power network), self-throwing and not self-reset (powernetwork to power network), self-throwing and self-reset (power network to powergeneration), in order to satisfy different power changeover requirement.

It has communication interface with built-in RS485, and has two kinds ofcommunication agreement including MODBUS-RUS and electric meter 1997,which can realize real time data upload, distance data configuration and conditionmonitor, and can achieve the function of telecommand, telemetering, remotecontrol, and remote regulating. Remote vision can be achieved through matchingintelligent power distribution system.

4.Safe and reliable, and have fire control linkage function When fire disaster occurs to no fire control load, fire protection control center cansend signal to intelligent controller, cut off double power supply, ensure firedisaster load to break.
