The electric load controller with load over-voltage protection, over-current protection function, the controller can according to the need to set the load load protection voltage controller and voltage recovery, effectively protect the load from damage. When the current controller outputs short circuit or over current, the controller and the battery can be effectively protected, and the load and the alarm can be cut off.

Under load, the output of the controller is divided into two ways: one power down and two power down. When the voltage is lower than a voltage setting value, cut off a load two times under electric load important guarantee the normal operation, when the voltage is lower than the two voltage setting value off load two times when the battery power, protect the battery from damage.

The utility model is suitable for the occasions such as the communication base station, the data center, and the like.
