DIN Rail Adjustable AC 380V 3 Phase Over and Under Voltage Protector Relay Voltmeter Monitor Phase Sequence Fault Protection

DIN Rail Adjustable AC 380V 3 Phase Over and Under Voltage Protector Relay Voltmeter Monitor Phase Sequence Fault Protection

STVP series automatic overvoltage and undervoltage protectors are suitable for three-phase AC 380V, 50/60Hz, rated working current of 40A or 50A or 63A or loads below 80A.

Its main feature is that when the circuit has overvoltage or undervoltage, the product can instantly cut off the power supply, protect the electrical equipment from damage, and automatically turn on the power supply to normal when the circuit voltage recovers.

Function:

1. Overvoltage protection
2. Undervoltage protection
3. Voltage display (independent ABC phase voltage measurement)
4. Three-phase voltage unbalance protection
5. Phase sequence protection (reverse phase protection)
6. Zero line disconnection protection
7. Phase failure protection
8. The overvoltage protection value is adjustable
9. Overvoltage recovery value is adjustable
10. The overvoltage protection action time is adjustable
11. Adjustable under-voltage protection value
12. The undervoltage recovery value is adjustable
13. The action time of undervoltage protection is adjustable
14. Three-phase voltage unbalance protection value is adjustable
15. Three-phase voltage unbalance protection action time is adjustable
16. Power-on delay time is adjustable
17. The fault recovery delay time is adjustable
18. Reset mode selection
19. Troubleshooting
20. Factory data reset
