Ground Guard Power Conditioner

Engineered to satisfy demanding Point-of-Sale applications. Powervar Ground Guard Power Conditioners incorporate a low-impedance isolation transformer that provides networked systems with benefits beyond traditional power conditioning. Filter elements in the safety-ground circuit prevent the formation of “ground loops” common in networked applications. This “ground conditioning” feature, combined with a high-energy surge diverter and a power-line filter, completely eliminates the need for both dedicated electrical circuits and isolated ground wiring.
