OMRON Electronic Components Europe has announced a highly compact 500VDC power relay aimed at the pre-charge circuits in electric vehicle chargers, battery back-up systems for solar panels and other high current DC applications.

With a high switching capacity and high isolation, the new OMRON G2RG-X is ideal for inrush current control, for example to protect the peripheral circuits when storage battery charging is initiated, as well as in energy storage systems, inverters, servos, power supplies and UPS.

The OMRON G2RG-X achieves 500VDC, 10A switching capacity within a compact body with a footprint of just 13.5X29.0mm and a height of 26.5mm. The exceptional performance in a small component is a result of OMRON’s arc control structure and a 3.0mm contact gap.

Further features include a high level of isolation, with an insulation distance of over 8mm and an impulse withstand voltage of 10kV between coil and contacts.

The G2RG-X features a low coil power consumption of just 0.8W and has just one coil as opposed to two in alternative solutions, further reducing energy loss within the device. It is designed for two-pole series wiring, and has an electrical durability of 10,000 operations in this configuration. The relay is UL and TÜV certified.
