I use a triple, 2 adjustable, one fixed 5V. But there is a problem
with it, it generates large V transients when turning off, which
can fry a circuit if you are not aware. So I unplug loads, then turn
off. Pain in the hiney, otherwise its a good supply. Problem with
this is you dont know when you purchase. I recommend you google
this as a problem for a specific model you are interested in to see
if anyone else reporting the problem.
You could always buy and return on eval, but shipping costs to do so
a burden. If you do this set your scope on one shot, say 1 mS sweep,
and a trig V just above the current V you have it set for. See if you
get any significant transient. Mine produces 50V+ transients..... I need
to add this to my fixit list ....
This happens to be model
