Re: Power supply options

Yeah, I know about the drivers and everything. I was just thinking
of using this variable DC source as the power supply for my drivers.
I have some IMS bi-polar drivers that I hook up to my PC running
Mach 2 and other programs. My current power supply is only 12V and I
would like to raise it a little to see if it would help out on motor
performance a little.
