Wiremold® Sentrex® High Performance Surge Protector Series and the Perma Power® Computer Grade Surge Protector Series include a wide range of solutions for point-of-use surge protection applications. By dissipating and diverting excess voltage, Sentrex and Perma Power surge protection devices keep your critical systems functioning properly. Electrical surges are present in every AC power system. They can penetrate a facility via AC, telephone, and communication lines, or on any other wires that enter a building. Surges and noise are also generated inside a building by fluorescent lighting, office machines, electric motors and HVAC equipment. Surges can strike once a month or hundreds of times a day, destroying data and damaging valuable hardware. Sentrex High Performance Cord-Ended Surge Protectors provide maximum protection for advanced electronic equipment. Perma Power Computer Grade units provide excellent point-of-use surge protection for personal computers, all-in-one machines, home electronics and appliances.
