    DFY-6 in order to protect the counter is a kind of multi-functional three-phase power system or three-phase electrical equipment monitoring and protection equipment. Set time, three phase voltage display, 20-the over-voltage protection, owe voltage protection, phase lack protection (broken phase protection), sequence protection (wrong phase protection) in one body. The Chinese LCD display, with complete functions, performance stability, simple operation, etc.

    DFY-6 sequence protection counter can real-time display three-phase power supply voltage, and can occur in power over/under voltage, phase lack, fault fault by relay output is equal in the form of movement of the protection circuit output contacts control signal, protect. Is replacing the traditional sequence relay and voltage relays of high-tech products.

The main function
1 display voltage: display the current working voltage values.
2 over voltage protection: voltage is too high or too low, cut off the power equipment.
Three phase lack protection: the three phase power phase lack power equipment when cut off.
4 the wrong phase protection: the three phase power sequence mistake cut off the power equipment.
5 20-the timing: record number of times and the accumulative total equipment start work time.
6 fault record: record fault happen times and total time.
