220V 110V Adjustable Over Under Voltage Protector 50/60Hz 63A Solar photovoltaic Inverter Lower Voltage Current Meter Relay (220V-240V)

The NanQue NQVPD2J-63 Adjustable Over/Under Voltage Protector is a reliable solution for safeguarding solar photovoltaic inverters and other electrical equipment from damaging voltage fluctuations. Compatible with both 110V and 220V systems and supporting 50/60Hz frequencies, this versatile device is well-suited for a wide range of residential and small commercial applications. Rated at up to 63A, it features a built-in current meter relay that provides real-time monitoring of both voltage and current via dual LED digital displays, enabling automatic power cutoff when unsafe conditions are detected. Indicator lights for overvoltage (OV), undervoltage (UV), and overcurrent (OA) make it easy to identify the cause of any trip event at a glance. The intuitive front-panel controls — including SET/INQ, up arrow, RES, and power buttons — allow straightforward threshold adjustments. Measuring approximately 36 x 85 x 67 mm and weighing just 50 grams, this compact unit is designed for convenient DIN rail mounting. Its simple two-terminal IN/OUT wiring configuration makes installation quick and hassle-free.
