Re: [TCML] Isolating Transformer
Excellent. Nice to have found a use for it finally, assuming it works...
haven't tried it yet!
What's the primary reason for using them, generally? Safety? Or
RFI/surge suppression? Or both...
On that note, how effective are they at suppressing surges, transients
etc.? I don't quite understand how voltage surges would be dampened inside
the isolation transformer. What's actually limiting the output voltage?
