Re: [TCML] Variable Inductive Ballast

Chris,
If you had the budget, I'd put one of these in each leg of your three phase power circuit. You would need three units, but I've had good luck running my TCs with saturable reactor ballasts. They are infinitely adjustable with the rectified output of a small Variac. 

Perhaps they would give you a price break on three of them.

Greetings gentlemen,

As part of the new High Voltage Lab at The Geek Group, I am looking for the
perfect current limiter for our test rig. My dream is a variable inductive
ballast system that can operate at anywhere from 0-560VAC 3Ph (we have
input voltage control sorted out already), limiting currents up to 400A
down to as low as possible. It doesn't have to be infinately variable, it
could be stepped. I would prefer steps of something like 5A, certainly not
larger than 10A.

I want to do this either with a custom built rig, or with something we can
get that is specifically designed for this application. The jank system of
old welders simply will not cut for this application.

Any ideas on where to get such a beast?
