Surge Protection & Filters

Power surges occur when there is a sudden increase of voltage sent through a power system from an internal or external force. Such forces can be caused by lightning strikes, electrical overload, faulty wiring or utility switching. Surge protective devices provide a line of defense against power surges preventing irreparable damage to equipment and costly downtime.

AC surge protectors, also known as surge protection devices (SPDs) or transient voltage surge suppressors (TVSSs), are electrical devices that are inserted into the alternating current (AC) line to protect electrical, data communication and telecommunication equipment from damage caused by lightning and electrical transient surges. The AC surge protector short-circuits to electrical ground any transient voltage that goes above a certain threshold while allowing the flow of normal current to remain unaffected.

DC surge protectors are devices that are designed specifically for direct current lines. Unlike AC, that oscillates back and forth, DC remains at a constant voltage. This makes arcing a bigger hazard and the surge protection device must be designed with additional arc extinguishing measures.
