PV Voltage Protector

MT53PV

MT53PV photovoltaic grid-connected remote control module is mainly used in distributed PV grid-connected power consumption systems. When the voltage on the photovoltaic side is overvoltage or undervoltage, it will automatically delay opening, and when the voltage is average, it will automatically close. When the voltage is too low, the automatic delay circuit breaker will trip and is lost.
