Providing compact, high-capacity relays with ultra-low contact resistance for the "distributed system" of clean energy power generation equipment
There is a trend to shift from centralized systems to distributed systems in clean energy generation facilities such as solar power generation systems.
In addition, with the shift to main power sources, facilities are becoming larger, and the capacity of PV inverters is increasing. Due to these situations, heat generation in inverters has become a problem. Compact, high-capacity relays with ultra-low contact resistance help solve heat generation problems.
Solar power generation equipment
OMRON's proprietary technology*1 has achieved an ultra-low contact resistance of 0.2 mΩ *2, reducing temperature rise by approximately 30% compared to general relays.
＜Simulation conditions＞
480 VAC/200A, ambient temperature 85 deg C, fans, ducts, and heat sinks
used, one on board.
*1 According to OMRON research, July 2021
*2 Default value
Capable of energizing and interrupting 200A despite its compact size.
Simplified heat dissipation structure reduces PCB area
