Still a place for the efficient high power DC relay

September 04, 2014 // By Graham Prophet
To address the growing market for high voltage DC battery powered systems and renewable energy applications, Omron has added an efficient DC power relay suitable for bicycle and scooter charging stations, UPSs, battery management systems, elevators, industrial robots, and solar/wind generation systems.

The Omron G9EJ-1-E is capable of interrupting 15A at 400 VDC with a power draw of 1.2W while switching. In order to allow the relay to interrupt high currents without the contacts deteriorating, the device features a proprietary high efficiency magnetic circuit that suppresses arcing. The G9EJ-1-E also has Omron's proprietary contact driving system, which improves inrush current withstand performance and enhances component life.

Measuring 31 x 27 x 44 mm, the relay weighs 50g and offers a compact, efficient solution for switching in high voltage DC powered systems. Features include insulation of 1000 MΩ between contacts and a sealed housing. A wide contact gap gives a high dielectric strength of 2500 VAC. Mounting brackets allow the application designer to secure the relay in any position. The relay is supplied with spade terminals allowing quick connection with industry standard connectors. The relay carries UL/CSA and VDE approval to support international applications.
