Over And Under Voltage Protection Device

CNKA Over And Under Voltage Protection Device Introduction

China Factory CNKA's customized overvoltage and undervoltage protection device, detailed in our price list, is designed with imported and reputable domestic components using advanced manufacturing technology. It quickly and reliably disconnects the power supply to safeguard household appliances from high voltage surges and undervoltages. Once the voltage returns to normal, the device will automatically reconnect the circuit and restore the power supply after a certain delay, protecting electrical equipment and minimizing the impact of power fluctuations without requiring manual intervention. Additionally, the device features dual indicator lights for easy selection and use.

CNKA  Over And Under Voltage Protection Device FAQ

Q: The voltage is very stable, and many electrical devices come with overvoltage/undervoltage protection functions, so there is no need to install additional over and under voltage protection device?

A: There are still fluctuations in the power grid, such as during the peak summer electricity consumption period, when people concentrate on using air conditioning and other equipment, the voltage may be low. At this time, although some household appliances are designed with overvoltage/undervoltage protection circuits, or some appliances allow a wide operating voltage range. However, long-term operation of household appliances at low voltage is bound to cause damage to the motor itself and affect the service life of the product. For example, if a power outage occurs accidentally due to a transformer or distribution room malfunction in a residential area, the voltage is relatively high at the moment of the power outage, and at this time, the household appliances are most likely to be damaged. In general, in this situation, the power supply company will ask residents to calculate losses and provide free repairs, but the repaired ones are not as good as the original ones.

Moreover, not all household appliances have a wide working voltage, and the self resetting overvoltage/undervoltage protector is mainly installed at the main switch of the incoming line of the residential distribution box to protect the entire line, that is, to avoid damage to various electrical equipment in the home when overvoltage/undervoltage situations occur in the power grid.
