OMRON Electronic Components Europe has introduced the G9EJH-1-E ultra-compact DC power relay, delivering a space-saving solution for inrush protection in battery-charging systems up to 800V. With class-leading dimensions of 31mm x 27mm, and 30mm high, the relay also meets the IEC 60664 insulation distance specification to satisfy stringent reliability and safety standards.
With its high maximum voltage and industry-standard insulation distance, the G9EJH-1-E is well suited to use in battery energy-storage systems (ESS). The compact dimensions, as well as 12V coil-operating voltage, simplify integration in pre-charging, auxiliary power, and main charging systems in hybrid and electric vehicles (EV/PHEV). Also, its 800V capability meets the needs of the automotive market as typical vehicle battery voltages continue to rise, targeting greater efficiency and faster charging.
With SPST (single-pole single-throw) normally open contacts, the relay operates in series with a current-limiting resistor for inrush protection. Capable of carrying a sustained current of 15A, and handling inrush current up to 30A, the G9EJH-1-E operates and releases within 30ms to provide fast-acting protection.
The contact resistance is less than 100mΩ, ensuring minimal power loss when turned on. On the other hand, the insulation resistance of 1000MΩ and dielectric strength of 2500V between the coil and contacts ensures robust performance in harsh conditions. Housed in a 6-pin PCB-mount package, the G9EJH-1-E is suitable for automated or hand soldering and ensures flexibility for assemblers while simplifying field repairs.
With a mechanical lifetime rated for over 200,000 operations and specified for operating temperature from -40°C to 85°C, the G9EJH-1-E ensures outstanding reliability in automotive and industrial environments. The relays are ready now for use in on-board chargers (OBC), service equipment (EVSE), and grid-connected energy-storage (BESS) applications.
