Overvoltage and Undervoltage Protectors are a protective device used to prevent the voltage in a circuit from exceeding a set value and damaging equipment. An undervoltage protector is a protective device used to prevent the voltage in a circuit from being too low and damaging the equipment or causing it to fail to function properly.

Principle of operation:
By monitoring the voltage in the circuit, when the voltage is lower than the set value, the low voltage protector will cut off the power supply or take other protective measures to prevent the equipment from being damaged or unable to work normally due to undervoltage.
Application Scenario:
Suitable for various occasions that require stable voltage supply, such as electric power system, industrial automation control system, household appliances and so on.
Features:
Characterized by high sensitivity, accurate action and reliable protection.
It can protect the equipment from under-voltage damage and ensure that the equipment works normally under a stable voltage environment.
Noted: When you first connect the product, you have to wait about 10 second( Power-on delay time:1 s~50 0s(default:10 s)), after the red light turn off, then the product will work.
In addition to separate overvoltage and undervoltage protectors, there are integrated protectors that provide both overvoltage and undervoltage protection. These combined protectors typically have more comprehensive protection characteristics and are capable of responding to multiple voltage anomalies at the same time, providing more comprehensive protection for circuits and equipment.
