At this point I am planning on the circuits requirements to be AC. While on the phone with the manufacturer, I believe he stated 36VAC or 36VDC. This morning I received the actual circuitry, the circuit board has printed on "AC36V". That's what I'm planning on until I can talk to the manufacturer tomorrow.
I have found 2 - 18VAC / 24VAC power adapters at Radio Shack. I plan on combining them, ( the 2 - 18VAC outputs to get my 36VAC, or maybe later combine 1 - 24VAC with 1 - 12VAC ) is this going to cause some problems that would affect my output?
Also, Hero999, stated that the circuit likely has a voltage doubler if it is using AC. Why is that?
Again thanks for the comments.
