Omron’s resistance relays for EV chargers and PV-powered homes

Omron Electronic Components Europe has expanded its high-power switching capability with the addition of a low contact resistance model for the successful two pole contact type G7L-2A-X series relays. With a 6.0mm contact gap, the new G7L-2A-X-SI relay provides low contact resistance of maximum 10mΩ and a rated load of 30A at 600V DC, or 25A at 1,000V DC.

The G7L-X series conforms to UK and IEC solar inverter standards, as well as applicable UL and VDE electrical standards.

Features of their design include an assisting magnetism circuit, to help achieve a very quick switchover. The relay contacts have been specifically designed to handle very high DC loads that are a feature of this application. Contact forms is two pole DPST and its 6.0mm contact gap ensures improved safety.

Driven by the trends for higher capacity and increasing heat generation issues, the G7L-X series enables reduced charging time for vehicle charging and offers high capacity for residential energy storage systems and battery storage management.

In comparison with similar level competitive relays, the G7L- 2A- X-SI has a larger contact gap, low contact resistance, and bidirectional switching ability.

Capable of 6,000 operations at 600V DC, or 100 operations at 1,000V DC, the relays provide higher capacity and low heat generation. The device is compact for a relay with this capacity – it measures just 52.5 x 35.5 x 41.0mm.
