DC Power Relays G9EA/G9EB/G9EC DC Control in a Relay A Leader in Clean Energy with Compact, Quiet, Energy-efficient Designs G9EB G9EA G9EC Compact models added to further expand SeriesDC P O W E R R E L A Y DC Power Relays that Interrupt High-capacity DC Loads and High-voltage DC Circuits in a Compact, Low-noise Design In the endeavors to prevent global warming, air pollution, and the depletion of oil resources, much attention is being given to increasing the efficiency of AC-to-DC power conversion and distributed power generation. DC contactors and circuit- breakers, however, are disadvantaged by their noise and bulk. OMRON has improved on the standard DC circuit that switches using a contactor or circuit-breaker by developing the G9EA/G9EB/G9EC DC Power Relay Series. These Relays enable switching high-voltage and high-capacity loads. The switch s gas-filled construction allows a considerable reduction in the relay switch size, while also lowering the operating noise during load switching. Furthermore, the new design has decreased the power consumption of the coil and achieved long-term contact stability. Features OMRON DC Power Switching Technologies Space-saving Quiet No arc space needed Sealed switching 50% lower operating noise Compact Gas-cooled arc Power-saving 70% less volume 30% less power consumption Magnetic arc control Safe, * Compared with the same class (load switching) reliable design of G9EA contactor.
