Benchtop power supply

Archiver

Can anyone suggest a good bench top power supply and where to get it? I'm
starting to play with stepper motors, and my wall warts just aren't cutting
it. I'm tired of trying to find just the right one with enough capacity for
what I'm driving.
I'm not allergic to spending a couple of hundred dollars, just as long as
it is a good one.

Dual outputs? Adjustable? Anything I left out?

This is kind of off topic, but I'm betting you guys are a pretty good resource.


Thanks,

You should be able to pick up a 2-3 amp 0-30 volt DC supply with adjustable
voltage and current for $100-200 depending on the quality. This should work
for the smaller steppers and most any motor you would use on a normal size
robot. They are advertised all over in Nuts & Volts.

Dual output is cool for op-amp work, just be sure you can turn the voltage
all the way down and that the power supplies can be tied together. One with
a +5 and +/- 12 would be even better.
