Re: [TCML] Giant Variac For Sale

Okay! I was little bit confused because of the additional "large transformer" you mentioned. What I was talking about, are units similar to yours, used for automatic "voltage stabilisation". They automatically adjust line voltage within a range of +/- some percent. These units consist of small variacs + big transformer, which takes the load. But anyway, you should check the namplate carefully. It says INPUT is 166-229 Volts and OUTPUT is fixed at 208 / 120 Volts. So this means, this unit can NOT regulate Voltage between 0 - 208 Volts! Is stabilizes the Output Voltage @ 208 Volts, whereas Input voltage can be anything between 166-229 Volts. 
So this is not a 75kVA Variac Mr. Boden...

If you check the pics, this is not a small variac. ;) It's a 6-stack
(triple-double) of the standard big toroids with balancing chokes. It's one 
size smaller than our 100kVA variac and will certainly handle the load.
Check the pics, the stack fills up half of that cabinet.

Nice! I also had such an big automatic voltage regulator some time ago.
"Problem" is: I don't remember how it works but the variac itself (which
would be interesting for TC use) is only a relatively small one, maybe
10kVA or less. The main power (75kVA in your case) comes from the big
standard 3-phase transformer, which is controlled via the small variac +
controll transformer.
Maybe you should add an info to your auction, that this is NOT a 75kVA
variac, this could lead to some confusion and you could get some trouble
otherwise :-)

If anyone is interested in a massive 6-stack variac, we have one for sale.

This happens to also include a solid cabinet with a large transformer and 
some control circuitry. The unit actually works, but who cares, it's a
giant 6-stack variac :)

And a matching massive switch as well
