Turtle Report post Posted June 14, 2016 Hello, I have a strange thing on one dimmer rack 6. Channel 3 only flick at full power, but if another channel is also on, it stay stable. From 0 to 80/90% is seems working fine. All solder look fine on the bottom. I'm not sure replacing the traic and the 12V zener diode was enought to cure the problem. Connected on 3 phases main power suplly, for the test with 75 W lamp on each channel. Does anyone have an idea ? Thanks Share this post Link to post Share on other sites
