When it comes to automatic voltage protectors, most electrical personnel are probably familiar with them. However, when it comes to the functions of automatic voltage protectors, the items they can protect, and the tips for purchasing them, many electrical personnel may only have a vague understanding of them, and some even know nothing about them. We all know that automatic voltage protectors are suitable for AC 50/60HZ power supply systems, and protect against indirect lightning and direct lightning effects or other transient overvoltage surges, and are suitable for surge protection requirements in the residential area.
Automatic Voltage Protector Introduction
Automatic voltage protector is a device used to automatically detect line voltage.
When the voltage in the line exceeds or falls below the specified value, it will automatically disconnect the circuit to protect electrical equipment from overvoltage or undervoltage.
When the voltage returns to normal, the protector will automatically close the circuit to ensure that the electrical equipment can work normally.
Automatic voltage protector AVP Working principle
When the power supply line has overvoltage or undervoltage, the protector will quickly cut off the circuit to prevent abnormal voltage from damaging electrical equipment. When the voltage returns to normal, the protector will automatically connect the circuit within a specified time to ensure that the electrical equipment can operate normally.
Main functions of automatic voltage protector
√ Overvoltage protection
When the line voltage exceeds the set value, the circuit is automatically disconnected to prevent electrical equipment from being damaged by overvoltage.
√ Undervoltage protection
When the line voltage is lower than the set value, the circuit is automatically disconnected to prevent electrical equipment from not working properly due to undervoltage.
√ Overcurrent protection
When the current exceeds the set value and lasts for too long, the protector will disconnect the circuit to prevent the wire from overheating and causing a fire.
√ Short circuit protection
When a short circuit or leakage occurs in the line, the automatic voltage protector will cut off the power supply in a very short time to prevent the line from burning or electric shock accidents.
The automatic voltage protector is suitable for households, mainly used in single-phase AC voltage 110V, 120V and 220v lines, as overvoltage, undervoltage, overcurrent and short circuit protection.

Tips for choosing voltage protector
√ Look for a warranty.
√ Make sure it has an indicator light.
√ Think about what you want to protect.
√ Get the right number of ports or sockets.
√ Identify the type of damage you want to protect against, such as direct lightning strikes, secondary impacts, or electrostatic discharge. This will help you choose the right circuit protection device.
√ Choose the right voltage rating based on the environment.
√ Cost considerations need to be weighed based on actual conditions.
How to use the automatic voltage protector correctly
√ Correct wiring
When using the automatic voltage protector, the wiring needs to be correct. Generally speaking, the AVP has an input and an output. You need to connect the power cord to the input and the electrical equipment to the output to ensure that the wiring is correct.
√ Correct setting
When using the AVP voltage protector, you need to set the voltage range correctly. Generally speaking, the voltage protector has two setting methods: manual and automatic. You need to choose according to the actual situation to avoid the voltage protector not working properly due to improper settings.
√ Regular inspection
After using the voltage protector for a long time, you need to regularly check the working status of the AVR. Generally speaking, the life of the voltage protector is about 3-5 years. If it exceeds the life, the voltage protector needs to be replaced to ensure the normal use of the electrical equipment.
