Re: Using 240VAC on 140VAC Varic
Original poster: DRIEBEN-at-midsouth.rr-dot-com
That would be me ;^) It starts saturating at around 180 to 200 volts
and at which point the current draw starts to go throught the roof. I
got a couple of ganged 140 volt 30 amp variacs through ebay once and was
lead to think by the add that they were each 280 volt at 30 amp variacs.
Once I got them, I realized that the nomenclature tag stated 140 volts,
not 280 volts. I went ahead and tried hooking them up to another 240/280
volt variac and tried to gradually ramp up the input voltage to the 140
volt variac monitoring the voltage with a DVM. Like I said, at between
180 and 200 volts, the 140 volt variac started saturating, so running
a 140 volt variac on 240 volts would NOT work!
