Starworth AVS 30 Automatic Voltage Switcher 30A Surge protector for Fridge, Freezers & Appliances

The AVS30 overvoltage protector is a protective device used in power systems. Its main function is to monitor voltage and take protective measures when the voltage exceeds the set value to prevent electrical equipment from being damaged by excessive voltage. The following are the working principles and product advantages of AVS30 overvoltage protector:

1. Voltage monitoring: The built-in sensor of the AVS30 overvoltage protector can monitor the voltage in the power system in real-time. Generally speaking, the set rated voltage is within its normal operating range, and exceeding the rated voltage is considered an overvoltage state.

2.Overvoltage protection: When the voltage exceeds the set value, the AVS30 overvoltage protector will quickly take protective measures, such as disconnecting the circuit, triggering fuses or relays, to prevent damage to electrical equipment caused by excessive voltage.

3.Overvoltage recovery: After the overvoltage protection is triggered, the AVS30 overvoltage protector is usually in an open state until the voltage returns to the normal range. Once the voltage returns to normal, the protector will automatically reset, allowing the power system to continue normal operation. 250
