A surge protector is a device used to safeguard electronic equipment from damage caused by voltage surges. Its core working principle is as follows: When the voltage rises above or drops below a specified value, the protector will immediately cut off the power supply, thus preventing electrical appliances from being damaged due to abnormal voltage. After the voltage returns to the normal range, with a certain time delay, the protector will reconnect the power supply, ensuring that electronic devices operate stably in a safe voltage environment.
This protection mechanism is widely applied to various electronic devices in household, office, and industrial scenarios, such as computers, refrigerators, air conditioners, servers, etc. It effectively reduces the risk of damage to equipment caused by voltage fluctuations and extends the service life of the equipment.
