RE: Using 240VAC on 140VAC Varic

Hi Dan,

Yes.  I bought a variac from Oatley Electronics here in Australia that came
from the U.S.  It was rated for 0-140AC.  It was part of a 3 phase stack.
It workes fine up to 2kVA on 240VAC, as long as you do not try and use the
step-up winding.  If you wire it without the step-up, the variac draws about
30mA without load, which is fine - but if you try and use the step-up
winding, the variac draws about 320mA, so I suspect the core is saturating.

PS: The variac only cost me Aus$40 ;)

Ian.
