I'm using a 40amp solid state relay that has pot rate to be 500k. Will this regulate the element on one leg to element?
Yes, it will work great. Note that the power won't be linear with the pot (but it's close enough you might not notice). It's the same thing that Still Dragon and Auber sell for their cheap boil controller. Anyone curious search SSVR.
I learn something new every day. Thanks passedpawn.
What gr3 has is an SSR with a PWM inside it. Or at least it has the nominally equivelent circuity inside the puck. You control the On to Off ratio with an external potentiometer. The trigger voltage comes from the puck.
Back to the OP. Assuming you are running 120 VAC with Hot, Neutral and Ground. Yes, put one SSVR on the Hot leg of your circuit. Do not put a second SSVR on the Neutral leg, leave that as a direct connection from the device's Neutral point to AC socket.
If you are running 240 VAC, balanced power, that is an especially trick question. I could guess and assume, but I do not do that with 240 VAC. I would defer to somebody with specific knowlege.
