I'd need to see more of what's inside and the specs. Any commercial
supply should have both ripple and noise specs and in 0.1 or 0.10%
although those particular figures would be *very good*
Unfortunately even the click here for a larger photo just brings up
another page with the same size photo.
The previous one you listed turned out to be a real gem.
This one? As you say it appears to be a server supply, or rather similar
to one.

I asked specifically what are the specifications for ripple and noise as
well as peak and continuous current. Also if they come with manuals
and/or schematics. I also asked if they are new or used.
73 and good luck,
