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 overvolatage,under voltage or voltage loss in the line,and can automatic detection of wire voltage.It is a protector that canautomatically 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 over voltage occurs,and automatically connect the line after delay when the line is restored to normal without manual operation.
