Re: Overamping variac

Hi Jim,

So you would look at the amperage rating of variac and compare to amps
at the input rather than the output?

Agree on PII fan sturdiness, just burned out another one...

Thanks,
Paul

That's about 2/3 amp at 120; you can run it forever, and it'll be the
fan, not the variac, that burns out.

BTW, I think they run closer to 18 volts -- P2 fans aren't that
sturdy, I've gone through 3 of them driving them directly off the
variac -- they tend to self destruct around 25 volts
.
