Power Protection System
Main Function
1.Voltage display: display the current power supply voltage value.
2.High /low voltage protection: cut off the power supply when the value of the voltage beyond the setting value.
3.Loss phase protection: cut off the power supply when three-phase source phase loss occurs.
4.Phase sequence protection: cut off the power supply when three-phase source phase sequence errors occur.
5.Calculagraph and count: record the counts of equipment start and accumulative the running time.
6.Faulty record: record the fault time and accumulative time.
