Nope. The dc side of the SSR controls the flow on the other side.

Only 1 leg of 240v or the hot side of 120v flows through the SSR on the switched side. This is where the AC is.

The control circuit is DC and controls the off/on of the Solid State Relay.

AC is being converted to DC by the wall transformer to power the PWM.

Yes, as the previous poster noted. DC is fed to the control side of the SSR. The AC voltage passes through the switched side.

IF your using 120V you may want to look at this thing:

So i bought all the components from mouser to build walker's pwm. I have it all assembled and hooked up to my ssr. The ssr I have has an led indicator light. My question is should this light be blinking at a rate that matches how far up I turn the pot. Right now once I turn the pot on the light goes on steady.

One thing that happened to me is the wall wort I was using for power turned out to be lower voltage than the 12V it was rated for. It would only power my test light solid. Once I hooked up another wall wort that truly did put out 12V, it worked as it was supposed to.
