I have Modicon ASP 484-600 and AS-P800-003 power supplies that are used and surplus. I also have a residential central heat and air unit that has a burned up transformer (primary 120vac and secondary 24vdc 40va). Can I cannibalize anything from the Modicon power supplies that can be adapted to the CHA unit? I am not an electrician but I learn quickly. I have already learned what happens when you get the wires mixed up on a transformer. I know the correct answer it to call someone that knows what they are doing, but I can’t afford it right now and winter is approaching.
