Thanks for that Bob.
I actually have that type of PSU (12V 20A or so) in my 3D printer but
it came as part of a kit (so I didn't spec it as such).
There are lots of vendors on ebay and they possibly all come out of the
same factory.
Quite possibly. A mate had some specialised garage kit that had a
similar PSU in it that was knocked out during a lightening strike. I
found him an exact replacement online that was about 45 quid including
next day delivery ... the suppliers of the garage equipment wanted 200
for the same thing. ;-(
I've used a number for various electronic applications.
Good to know. Oh, I did help wire a couple more up used as CCTV power
supplies. ;-)
The regulation is good and the output voltage is trimmable by a few %
either way and there is no minimum load.
OOI, what sort of overhead (if any) would you set on the capacity of
such a solution?
Say I measure 3A peak on boot and 2A when running but idle, would a 5A
model be overkill?
