@3rail posted:I am no Sparky.....but would not a basic good old wall wart work? As long as it has a 12VDC output, I think it would be fine. I know that is what I use for lighting circuits that use DC instead of AC for power. Cut off the plug and wire it to the (2) inputs.
I must have a dozen or more I collected over the years in a box.

I have a wall wart and being honest if it wasn't for my Lionel Command Switches which need AC, I'd use DC for my accessories. I really don't feel like rewiring separating my accessories and switches. I suppose I could if I absolutely had to.
