Specifications

Power Protection Device uses microcontroller and digital processing technology; it integrates voltage display,

Main Function

1.  Voltage display: display the current power supply voltage valu

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.
