Overvoltage Protection Devices

China Suppliers ICHYTI Low Price overvoltage protection devices In Stock is an overvoltage and undervoltage protection device with automatic reclosing function. It can automatically disconnect the power supply when overvoltage and undervoltage in the circuit exceed the specified value, and can automatically detect the circuit voltage. When the voltage returns to normal, it will automatically close. This overvoltage protection devices is mainly used in household and shopping distribution lines (single-phase AC230V) for protection against overvoltage, undervoltage, phase loss, and zero line faults.

ICHYTI overvoltage protection devices Design principle

The overvoltage protection devices adopts a high-speed micro low-power processor as the control circuit core, and the main circuit adopts a magnetic holding relay with a modular standard design. When overvoltage and undervoltage occur in the power supply line, the overvoltage protection devices can quickly and safely cut off the circuit under continuous high-voltage impact, effectively avoiding damage and accidents caused by abnormal voltage to terminal appliances. When the voltage returns to normal, the overvoltage protection devices will automatically connect the circuit within the specified time, ensuring that the terminal electrical equipment operates normally without anyone on duty.

ICHYTI overvoltage protection devices FAQ

Q: What is the difference between an overvoltage/undervoltage protector and a self resetting overvoltage/undervoltage protector?

A: Most of the time, this type of overvoltage/undervoltage protector, as an accessory, needs to be combined with the circuit breaker for use. When the voltage in the circuit is unstable, the release of the overvoltage/undervoltage accessory will pull the handle of the nearby circuit breaker to achieve tripping. After the circuit breaker trips, even if the voltage of the circuit returns to normal, the circuit breaker and overvoltage/undervoltage accessories cannot be automatically reset. It is necessary to manually push and close the handle of the circuit breaker to restore power supply. This is more troublesome for areas with unstable power supply. When people go out to work, they always feel uneasy, worried that their refrigerator is broken, and worried that their fish may lack oxygen. 

When decorating some households, they may not pay enough attention and choose such overvoltage and undervoltage accessories.In addition to having the basic function of overvoltage and undervoltage protection, the dual overvoltage and undervoltage protector also has a requirement that when the voltage in the system returns to normal, the power supply will be automatically restored, without the need for manual operation such as pressing buttons. If there is still a problem with the voltage, it will trip again. The advantage of this release is that it is more convenient and more suitable for ordinary household users.
