First time I have seen it.
ES> As I mentioned before, I have a 12kv 60ma and a 12kv 120ma
ES> transformer. Because they are unequal, I will need to run
ES> each off of 120v - probably using two separate circuits. If
ES> I ever want to run these off of 240v I need to get another
ES> 12kv 60ma transformer and parellel the other 60ma and then
ES> connect those in series with the 120ma transformer - yes?
Yes. That is correct.
ES> A new question: I found a good deal on 120volt 10amp
ES> variacs and had to buy three ($10.00 each!). Any way to use
ES> these in parallel?
Yes. You can gang variacs provided the cores are set up so that a
single continous shaft can be run through the centers of all the
units in the gang; and all the variacs to be ganged have matched
windings. In my large power cabinet I have two 28 amp powerstats
ganged on a common shaft for a paralleled thruput of 56 amps.
ES> I could run both of my transformers with pfc correction and
ES> be just over 20 amps.
That would work just fine.
ES> I have also found a 120 volt 41amp variac that I could get
ES> for $75.00 and a 240 volt variac at 40 amps for probably
ES> $125.00. I haven't decided on these yet. Wish I had lots of
ES> money. :-)
I don't know what you wanbt to hear, but that is an excellent
price on the 240 volt variac. I would snatch that one up at the
... If all else fails... Throw another megavolt across it!
