Simple Variac Question
What if you used a secondary transformer with a Center Tap and used the
VARIAC to control the AC input? I guess that's a pretty simple question,
but just want to make sure I'm not missing something.
No, because there is no centre tap on a variac. Electrically, it is just a
variable auto transformer. One output leg is common with one of the line
in legs.
