Used for switching power supply (inverter output) from solar panel and household power supply
From Japan
On 2017-12-21 13:44:37
Since the control panel of the company that I worked in before was using OMRON products and it was a very reliable part, this time I installed a solar panel on power saving at home and is using it for switching AC power. Switching instantly without cutting, I am very satisfied.
