OK, I took a look through the louvers on the top of my "Epsco NFB 32V/15A" this morning. I was wrong on the rating. It's the same as yours. It's a Variac style variable auto transformer.
You can buy any number of 30VDC/20A CV CC bench supplies from $250 to $400... if that's what you need. If I was going to have only one bench supply in that rating range, I would go for one of those. Which I did. But when the Epsco showed up, I found many uses for it off the bench...electrolysis derusting, foam cutter, sheet acrylic bender, and wind tunnel fan. None require any special regulation, just adjustable voltage with a lot of current.
