Omron – Pre-charge relay for electric

Omron – Pre-charge relay for electric
Welcome to a Biomedical Battery specialist of the Omron Battery
A new pre-charge relay aimed specifically at electric and hybrid vehicles and other heavy duty battery powered systems has been launched by Omron Electronic Components Europe (OCB-EU).
The G9EJ-1 is specifically designed for use in pre-charge circuits used in electric vehicles and other battery systems to reduce the very high inrush currents on start-up. Before the vehicle or system is fully started, the pre-charge circuit is switched on briefly to charge capacitors in the controller and inverter through a current-limiting resistor. The G9EJ-1 is specifically designed to switch in this circuit with battery such as Omron 48H907N Battery, Omron 48H907N-AU Battery, Omron HEM-907 Battery, Omron HEM-907XL Battery, Fluke 199B Battery, Fluke 199C Battery, Fluke F199 Battery, Fluke F199B Battery, Fluke F199C Battery, Panasonic P-10S/F24G2 Battery, and is a cost-effective solution that can support up to 25A at 400VDC.
Omron has designed the G9EJ with a proprietary contact driving system that enhances the inrush current performance and ensures a long service life under these conditions. The G9EJ also features a high efficiency magnetic circuit which helps extinguish magnetic arcs which can damage the contact surface. The relay is amongst the smallest solutions of its type in the industry, sized at just 30mm x 27mm x 31mm and weighing around 50g.
The Omron G9EJ-1 complements the Omron range of power relays for the electric vehicle main power relays, which switch in the full motor circuit once the pre-charge phase is complete. These include the G9EC which can switch up to 200A at 400VDC.
