Low heat 200A relay for renewable micro-power generation

Omron is aiming at power conditioning in micro power generators, inverters and UPS with a 800Vac 200A relay designed to create little heat. Called G9KA, its first heat reduction technique is to have a low contact resistance. Its cadmium-free silver-alloy contacts have an initial resistance of 200μΩ (200A for 30min) – contact gap is 4mm (applied ...
