White Paper Overview

Today’s energy industry is rapidly evolving to renewable energy sources, including solar and wind, as the primary sources of electricity generation. While maximizing power availability, designers and manufacturers need to improve the reliability and safety of their systems in balance of the costs. To meet evolving needs in this sector, companies must constantly expand their range of components to support the next generation of energy systems. For Omron, this includes an expanding range of high-power PCB relays with a focus on low contact resistance to increase the safety, reliability, durability, and cost-effectiveness of your products.

The G9KB high-power PCB relay couples that focus with bidirectional switching capability and arc cut-off technology to support switching up to 50 A at 600 VDC. These qualities make the G9KB ideal for charging/discharging applications such as EV charging and energy storage systems.

Due to the quality and targeted design efforts of products such as the G9KB, our relays are trusted worldwide and are making an important contribution for more energy-efficient future.
