The function and setting of voltage correction value of voltage surge protector

A customer bought a voltage surge protector. He knew the high, low, and time values, but he had a question. He didn’t know what the voltage correction value was used for, nor did he know what it should be set to. This article by the voltage surge protector supplier tells you the role of the voltage correction value and how to set it.

‌The voltage correction value of a voltage surge protector mainly refers to its voltage protection level (Up), which represents the voltage-limiting capability of the protector under specific conditions. This value determines how much the protector can limit the voltage during a surge event, thereby effectively protecting the electrical equipment connected to the back end from being damaged by excessive voltage. ‌

The setting of the voltage correction value should be determined based on the withstand voltage of the protected equipment and the system’s demand for overvoltage protection. Generally speaking, the voltage protection level (Up) should be lower than the maximum voltage that the protected equipment can withstand to ensure that the protector can act in time to limit the voltage within a safe range when a surge event occurs. ‌

Specifically, if you know the maximum voltage that your device can withstand, you can set the voltage correction value (i.e., voltage protection level) slightly lower than this value to ensure that the protector can respond quickly and protect the device from damage when the voltage is abnormal. At the same time, you also need to consider the stability and reliability requirements of the system, as well as factors such as the response time and action sensitivity of the protector, to comprehensively determine the optimal setting of the voltage correction value. ‌

In general, setting the voltage correction value is a process that requires comprehensive consideration of many factors, including the characteristics of the protected equipment, system requirements, and the performance of the protector. It is recommended that you carefully read the user manual of the protector before setting it, or consult a professional electrician or technician to ensure that the setting is correct and reasonable.
