Omron Electronics G9KA PCB Power Relays support up to 800VAC/200A opening and closing and achieve ultra-low contact resistance of 0.2mΩ. The low contact resistance suppresses heat generation of the application and contributes to the improvement of heat issues. G9KA relays have a low heat feature that helps reduce material costs by eliminating heat sinks and extending the life of the application. Omron Electronics G9KA PCB Power Relays are ideal for industrial inverters, power conditioner systems (PCS), and uninterruptible power supply (UPS) applications.
