Adjustable Voltage Relay Control Over Under Voltage Protector 220V 110V 40A 63A 80A Overvoltage and Over Current Protection Devices Din Rail SVP series SINOTIMER brand automatic over-voltage and under-voltage protector is suitable for single-phase AC 230V or 120V, 50Hz, rated working current 40A or 63A or 80A or le loads. It is mainly used for residential household box entry or over-voltage, under-voltage or over-current protection of distribution lines for single-phase electrical equipment. Its main feature is when the circuit has over-voltage or under-voltage, over-current problems, the product can cut off the power supply instantaneously to protect the electrical equipment from being damaged, besides,the protector can automatically turn on the power supply when the circuit voltage returns to the normal.The green indicator display, when the power is normal supply.The red indicator display, when the power over voltage or under voltage. Functions: 1.Over-voltage protection2.Under-voltage protection3.Over-current protection4.Automatic recovery5.Voltage display(voltage measurement)6.Current display (current measurement) Product Parameters: 1.Model number:SVP-916 40A or 63A or 80A2.Power supply: AC 230V or 120V 50HZ3.Max.Loading power:1~40A or 1~63A or 1~80A Adjustabledefault:40A or 63A or 80A4.
