I can't think of any real reason it can't be done. But at 4 amps your going to be pushed on max power dissipation vs power supply voltage. (after looking at the kit I suspect they are doing just that. 3 term adjustable regulators with a resistor to set current, major fan to dissipate heat). I've been toying with a design of a chopper adapter. But the drawing board is all the farther it has gotten.
Phil, Still too many interests, too many projects, and not enough time!!!!!!!!
