Hello, First time I post here, so bear with me. :smiley: I am bulding a circuit to dim an AC light. Already built the zero cross detector with H11AA1, this one works. But the SSR will switch just from 12v. Tried with a BT137, can't get it working. My question is, How can I trigger 12v from the A…

ZeroCrossing AC Dimming

Some SSRs can be used for dimming, but not all.
Some only turn on at (near) zero-crossing and others are suitable for random fire.
