A new high-power printed circuit board (PCB) relay from Omron Corporation improves the power generation efficiency of photovoltaic generation systems. The device minimizes energy loss caused by heat generated by power conditioners, power supply equipment and related equipment used in solar power generation systems.
An ultra-low contact resistance of 0.2 milliohm suppresses heat generated by the relay and improves the power generation efficiency of solar power generation systems, thereby accelerating renewable energy

The relay helps to reduce the size and weight of equipment by simplifying the heatsink and cooling fan installed as a countermeasure against heat generation. In addition, suppressing the heat generated by the relay leads to a reduction in the temperature rise of the PCB, thereby contributing to the longevity of equipment.
Capable of energizing and de-energizing 200 A (800 V AC), the device 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.
