When there is an overvoltage, undervoltage, or overcurrent fault in the circuit, CNKA's adjustable voltage protector can immediately cut off the power supply to protect electrical equipment from damage. The overvoltage, undervoltage, and overcurrent values can be set independently and adjusted according to local conditions. If the line voltage returns to normal, the adjustable voltage protector can automatically restore the connection to the line and continue to provide protection for a period of time.

1 Within the voltage range between Uoe and Uvo, the protector will automatically activate.
2 When the line experiences instantaneous or transient overvoltage, the protector will not malfunction.
3 The protector is equipped with two colored LED lights to indicate its working status: green ON indicates normal voltage, and red OFF indicates undervoltage or over delay.
4 All automation functions do not require manual intervention, and users can utilize the dual indicator lights as needed.
Q: Why do we need undervoltage protection?
A: Undervoltage protection is essential for safeguarding motors from damage caused by abnormal voltage conditions and preventing breaker-fed motors from re-accelerating once bus voltage is restored. However, this protection method can also pose the risk of nuisance tripping when voltage transformers (VTs) fail.
Q: What are the dangers of overvoltage?
A: Transient overvoltages can cause degradation in electronic components and circuits without being noticed by users, which shortens the lifespan of equipment and increases the probability of failures. Severe transient overvoltages can damage components and circuit boards, burn or destroy equipment, and even start a fire.
Q: What is overvoltage protection?
A: TheCNKAovervoltage protector is a circuit designed to prevent downstream circuitry from sustaining damage due to excessive voltage.
