40A 220V Adjustable Over Voltage And Under Voltage Protective Device

• Over Voltage And Voltage Protective Device With Auto-Reclosing Function (OUPA) is an intelligent protector integrated with an overvoltage protector, under voltage protector, and over-current protector. In case of an over-voltage fault, under-voltage fault, or over-current fault in line, this product can instantly power off to prevent electrical equipment from being burnt. The over-voltage, under-voltage, and over-current values of this product can all be set up by yourself and can be adjusted based on local practical conditions.

Product features：

• The voltage can be set according to the power consumption state. The intelligent chip shows that the current power consumption voltage exceeds the voltage and automatically breaks off.
• Intelligent anti-interference, The anti-interference performance of intelligent chips is improved to solve the problems of FM instability and fluctuation.
• In case of an over-voltage fault, under-voltage fault, or over-current fault in a single phase line, the product can power off the line and can automatically restore connecting the line over a time delay after the voltage of the lien is recovered to normal condition.
• In case of transient overvoltage in line, the product can protect the equipment from false operation.
• In case the line is subject to unstable voltage or sudden power-off due to a loosened connection and other faults, the product will disconnect the line.
• When the fault voltage of the line reaches the peak, the product itself will not be damaged.
