sylvesterb posted:Thanks for the quick reply and info gunrunnerjohn. I may have not given enough information to start but I have an 14vac buss for accessories and building lights. It looks like this unit used dcv for power and switches acv.Is there something out there that I can power off my existing buss?
For your specific application (relatively low power) you could use a regulator module that converts 14V AC to regulated 12V DC. Less than $2 on eBay with free shipping from Asia. 2 wires in, 2 wires out with convenient screw-terminals.
Search eBay for "LM7812 regulator module". It appears some are a kit version (i.e., assembly-required) even though the listing doesn't mention this.
