Surge Protection Device DC 500V~1500V Manufacturers GRL

Surge Protection Device Overview

A Surge Protection Device (SPD) is an electrical device used to protect sensitive equipment and electrical systems from voltage spikes or surges. These surges can be caused by lightning strikes, power grid switching, or sudden interruptions in power flow. Without proper protection, these sudden voltage increases can damage or destroy electrical equipment.

How surge protection device Function？

The SPD operates by continuously monitoring the voltage in the electrical system. If it detects a voltage surge exceeding a certain threshold, the SPD’s internal components activate to divert the excess energy to the ground. This prevents the excessive voltage from reaching and damaging connected devices, ensuring the system remains operational and protected.
