Umm, sorry to say based on personal experience I would not recommend
those supplies AT ALL.
They have a hidden 5th memory, which by default is set to max volts
and max amps. You get to it by accidently touching the dial in a
certain way. Great way to fry several prototype boards. Not.
All the ones at work now have the memories set to 0V and 0A. Just in case.
