- OMRON launched G9KD and G9KJ relays for next-generation high-voltage energy applications.
- The new relays support compact 800V and 1,500V EV charging and ESS architectures.
OMRON Electronic Components has introduced its new G9KD and G9KJ high-voltage DC power relays to address the evolving requirements of advanced energy platforms. The newly launched relays are engineered for applications including EV charging infrastructure, energy storage systems (ESS), and V2X systems, where higher voltage handling, compact packaging, and operational safety are becoming increasingly important. The announcement reflects the industry's growing transition toward high-performance electrical architectures capable of supporting next-generation electrification technologies.
The G9KD relay has been developed as a high-capacity PCB power relay capable of switching up to 1,500 VDC while carrying currents of up to 150A. This capability makes it suitable for use in main circuit applications within demanding high-voltage energy environments. With growing adoption of high-voltage EV platforms and large-scale energy systems, components that can reliably handle elevated power loads while maintaining system stability are becoming critical across the automotive and energy sectors.
The G9KJ relay complements the G9KD by functioning as a compact pre-charge relay specifically optimized for current management in high-voltage DC systems. Designed primarily for pre-charge applications in EV charging and ESS platforms, the relay helps protect system components from excessive inrush current during startup operations. By supporting controlled power delivery, the G9KJ contributes to improved system reliability, enhanced operational safety, and better protection for sensitive electrical architectures.
Both relays have been designed to support the transition toward advanced 800V and 1,500V platform architectures that are increasingly being adopted in electric mobility and energy storage applications. Alongside higher voltage compatibility, the products also address industry concerns related to thermal performance, space optimization, and overall system efficiency. These factors are becoming more significant as manufacturers seek compact, lightweight, and high-efficiency solutions for next-generation electrified systems.
