The main function of DC surge protector

2023-10-18

The main function of a DC surge protector is to protect electronic devices from voltage spikes or surges in a direct current (DC) electrical system. These voltage spikes can occur due to lightning strikes, power outages, or other electrical disturbances, and they can damage or destroy sensitive electronic equipment such as computers, telecommunication systems, and industrial control systems.

A DC surge protector works by diverting the excess voltage away from the protected equipment and into a grounding system. This is typically accomplished using a series of metal oxide varistors (MOVs), which are voltage-sensitive devices that can conduct large amounts of current when a voltage surge occurs. The MOVs are connected between the protected equipment and the ground, and when a surge occurs, they activate and shunt the excess voltage away from the equipment and into the ground.

In addition to MOVs, DC surge protectors may also incorporate other protective features, such as fuses or circuit breakers, to provide additional protection against overcurrent conditions. Overall, the main function of a DC surge protector is to provide a safe path for excess voltage to dissipate, protecting sensitive electronic equipment from damage or destruction.
