New relay extends current capacity for EV charging and UPS

08-09-2023 | Omron | Power

Omron Electronic Components Europe has extended its G7EB high-power relay portfolio with a new 120A carry type for control and instrumentation applications, including PV inverters, EV charging and UPS. The new G7EB-1A-E supplies the key advantage of heat generation suppression, which lessens contact resistance compared with competitors.

The new device extends the existing G7EB relay capability by improving the rated carry current from 100A to 120A and allowing 30,000 operations with 40A make/break and 120A carry currents.

Increasing demand for data centre capacity entails higher capacity for the relays in associated UPS. For example, extending 400V three-phase UPS from 60kVA to 80kVA needs increasing relay capacity from 100A up to 120A.

AC input applications in EV charging systems are another target application for these latest high-power relays. The 120A model suits Mode3 EV chargers operating with single phase 19.2kW for inverter switching. Also, the new relays supply the 20kW DC charger necessities of DC-output EV chargers using Mode4 and V2H AC input inverter switching.
