Omron G9KA PCB Power Relays
Omron G9KA PCB Power Relays support high-voltage and high-current switching in compact board-mounted designs. These relays use a single-pole normally open contact structure with an Ag alloy contact material and a wide contact gap. The G9KA PCB power relays feature an operating temperature range from -40°C to +85°C and 200A carry current. These devices come with a maximum contact resistance of 0.2mΩ and a maximum operating time of 30ms. Applications include power conditioner inverters, industrial inverters, and UPS equipment.

High voltages are like pet scorpions: they’re great if you know they’re contained and behaving well. If not, you might get stung. Thankfully, it’s easy to keep your high voltages under control with Omron’s G9KA PCB Power Relays. These relays are capable of switching up to 800VAC at 200A, and capable of withstanding 10KV impulses. The ultra low contact resistance of less than 0.2mΩ means that when operating at max power, the relay still keeps its cool, and the wide operating temperature range of -40°C to +85°C means you can take your high voltage switching applications almost anywhere. With all of these features considered, the G9KA PCB Power Relay series is perfect for high-power AC applications, including uninterruptible power supplies, industrial systems, and power conditioners.
