90 or 180VDC motor controllers will NOT work for powering pelts!

The motor controllers do not care about ripple, and most of them are pulse width modulation (PWM) anyway. Which will burn up a pelt fairly quickly, as has been said.

The PS inside one of the Thermotek 25x series chillers is a smps that puts out 65vdc @ 7+A. The pelt assy is made of 10 pelts in series running at about half voltage.
