G9KA High Power PCB Relay with Ultra-Low Contact Resistance and High Impulse Withstand Voltage

OMRON Corporation has released G9KA High Power PCB Relay to improve the power generation efficiency of PV generation systems by minimizing energy loss caused by the heat generated by power conditioners, power supply equipment, and related equipment used in solar power generation systems. Its ultra-low contact resistance of 0.2mΩ＊2 suppresses the heat generated by the relay and improves the power generation efficiency of solar power generation systems, thereby accelerating renewable energy deployment and contributing to the realization of a decarbonized society.

The G9KA can reduce the temperature rise of the relay about 30%*3 - compared with conventional high-power relays - by lowering the contact resistance to the industry-leading*1 0.2mΩ*2. This product helps to reduce the size and weight of equipment by simplifying the heatsink and cooling fan that were installed as a countermeasure against heat generation. Moreover, suppressing the heat generated by the relay leads to a reduction in the temperature rise of the PC board, thereby contributing to the longevity of the equipment.

This product can be used in equipment and applications where large current loads need to be cut off, and can also replace contactors that are primarily used for high-capacity power control applications.
