PRODUCT INTRODUCTION

DHOV3 overvoltage and undervoltage protector is an intelligent adjustable voltage protector. integrating overvoltage protection, undervoltage protection and overcurrent protection. Applicable to single-phase AC voltage 220V / 120V, rated working frequency 50/60Hz, Maximum working current 63A. In case of over-voltage fault, under-voltage fault and over-current fault in the Live wire , this product can instantly cut off the power supply and protect the electrical equipment from burning. When the line returns to normal, the voltage protector can automatically reconnect the line. The overvoltage value, undervoltage value, overcurrent value and protection time of the product can be adjusted. It is mainly used for overvoltage/undervoltage protection of incoming lines of residential, photovoltaic and factory distribution boxes.

The width of DHOV3 adjustable voltage protector is 36mm. The control current is very convenient to install in the distribution box. The control circuit board is assembled with imported components. The product is produced according to modular standard, with excellent performance and reliability. It can work normally under abnormal voltage conditions. When the mains voltage exceeds the overvoltage action voltage value set by the protector or is lower than the undervoltage action voltage value of the protector, the protector can quickly and reliably cut off the circuit to protect the safety of the appliance. When the mains voltage returns to normal, the protector can automatically delay the power connection and restore the power supply. All functions are automatically realized without manual operation. The LED on the panel can indicate the working status of the protector. The green light of the indicator light indicates the working power supply. When the red light of the indicator is off, the power supply is normal. When the red light is on, the protection function starts to cut off the power supply. The self-reset overvoltage and undervoltage protector has compact structure and beautiful appearance, and is installed with 35MM DIN Rail
