Digital display self-recovery over-voltage protector is mainly used for photovoltaic grid-connected, household, and similar low-voltage distribution lines. It can automatically disconnect when there is over voltage, under voltage or voltage loss in the line, and automatic detection of wire voltage. It is a protector that can automatically be closed when the line of electricity back to normal.
Features:
- The over-voltage and under-voltage protection threshold is adjustable, which is convenient for the user to set the voltage protection range in real-time according to the power consumption environment.
- It can cut off the line in time when the overvoltage occurs, and automatically connect the line after a delay when the line is restored to normal without manual operation.
- Display range of effective voltage 70-400V
- Withstand lightning surge voltage:5KV
