Howdy all -

Revamping the shack desk here & looking for recommendations on 20A switching power supplies Re reliability, heat generation, digital/RF noise generation, size, costs and features.  Had an open-frame 50A switcher years ago out of some unknown surplus equipment that generated S9+30dB square wave noise from 60 Hz to about 900 MHz, put me pretty much all the way off of using SPS's at all, but need to reconsider due to size constraints on this project.

All info positive and/or negative welcomed, TIA.

Best 73,
