RE: [TCML] Variac question

["Henry Hurrass" <dr.hankenstein@xxxxxxxxxxxxx>]

That's a very good idea. Saves a lot of space and still nets you 240VAC @ 22 amps. Only difference, as you noted, is the requirement of the neutral leg for reference, thus a "3-wire 240VAC" instead of "2-wire 240VAC". I presently have a Tesla coil controller and a 1KW AM transmitter controlled in this fashion and love it.

Kind regards,
Hank

Subject: [TCML] Variac question

So, I acquired a pretty nice variac the other day, Powerstat 136BU-2 in a sweet shell. 

It has two cores with the brushes on a common knob, each rated for 120V 22A. with a matching transformer in the back. 

I was thinking about ignoring the matching transformer and rewiring it to make each core one leg of 240V line and the neutral. Thus giving me 240V at 22 Amps. 

Any issues with doing this? Seems like a pretty decent way to go from where i'm sitting. 



Cheers,
