Well of course! Galvanic Isolation! Why didn't I think of that? I must have used that term NEVER in my programming career!
Anyway, Stan, I think I understand the concept at a basic level. The AC from the internal transformers (through inductance) create an independent source that can be run through a bridge rectifier without causing any problems when mixing AC and DC through the same conductor. That's a good thing to know. Thanks!
