RE: [TCML] Slide choke question
DC,
Was the core made of silicon steel flat laminations? That's a rocking
ballast as the younger folks say. Has it powered Big Bruiser? Please forward
me a picture as of course the list doesn't allow attachments or if you don't
mind, someone could post it? That's a hard core to "outgrow"!
Thanks,
Jim Mora

photo attached.
This was 300 turns of 2 AWG for 100 Amps at 220 VAC. Core size is 3 x 3"
square x 20 inches long. gave us very smooth control 2-100 Amp range.
for 30-40 Amps you could use a 2 x 2" core size.
if you have questions, call me at tel 608-356-3647 daytime CST 9:30 - 11 AM
or 2-4 PM most everyday.
