Yamaha Integrated Amplifier Relay Exchange
From Japan
On 2018-05-15 18:36:54
In 1987 I used it for the replacement of the Yamaha Integrated Amplifier relay (existing from DEC). It works without problems.

Replacing the control box relay
From Japan
On 2018-04-27 10:23:09
At the time of switching on / off, I tried to replace the drive because of error of reading drive. I'd like to exchange another if it is okay to try it for a while.

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.
