DC relay addresses renewable applications

03 September 2014

The G9EJ-1-E is capable of interrupting 15A at 400V DC yet draws only 1.2W while switching, claims Omron.

To address the growing market for high voltage DC battery powered systems and renewable energy applications, Omron Electronic Components Europe (OCB-EU) has added the DC power relay for bicycle and scooter charging stations, UPS, battery management systems, elevators, industrial robots, solar / wind generation systems and other applications.

In order to allow the relay to interrupt high currents without the contacts deteriorating, proprietary high efficiency magnetic circuit suppress arcing. The replay also has the company’s proprietary contact driving system, which improves inrush current withstand performance and enhances component life.

Measuring 31 x 27 x 44mm and weighing 50g, it has a high insulation of 1,000M? between contacts and a sealed housing. A wide contact gap gives a high dielectric strength of 2500V AC. The 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.
