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.
