Fans Single Phase Voltage Monitoring Relay , Phase Loss Monitor Relay with knob

1 When the single-phase line is over-voltage, the line is cut off and the voltage of the single-phase line is restored to normal. After the delay, the line is automatically reset and no manual operation is required.
2 When a transient or transient overvoltage occurs on the line, the protector will not malfunction.
3 If the line is unstable due to faults such as inaccurate contacts, or sudden power failure and sudden incoming call, the protector does not connect the line.
4 When the line fault voltage is highest, the protector itself will not be damaged.
5 The protector is in reverse time action characteristics, action time ≤ 1s.

The overvoltage protector can effectively limit the atmospheric overvoltage and the operation overvoltage caused by various vacuum circuit breakers, and can reliably restrict the phase-to-phase and relative overvoltage, and it has a compact structure and high voltage insulation. Characteristics, greatly utilize and reduce the use of space, it is widely used in electrical power, metallurgy, petrochemical, mining, construction and environmental protection and other fields of electrical equipment protection.

SVR series single-phase voltage protector (also known as voltage monitor, over-voltage protection, etc.) is mainly used for AC 50/60Hz, rated voltage below 250V, industrial single-phase 110V, 220V, 240V, 250V and other voltage levels of various Fault detection provides relay protection for high voltage and low voltage of single-phase input power supply. It is an indispensable protection product for maintaining the normal operating voltage of industrial equipment during operation.

Single-phase 220V power supply error shall not be more than plus or minus 10% of 220V, that is, when 220V is over 242V, it is called overvoltage; below 198V, it is called undervoltage. In the single-phase 220V power supply, 220V suddenly rises to 380V or 440V ultra high voltage, which is called overvoltage; when the grid voltage suddenly changes overvoltage, overvoltage and undervoltage, the device that can automatically cut off the power quickly and intelligently is called overvoltage. Overvoltage and undervoltage protectors.
