[Elecraft] 48 volt PS

[Bob]

Hi Ed,

       As a reference point. Elecraft uses a MeanWell RSP-3000-48 in the KPA1500 
power supply as shown on the FCC site.

       Does not show any extra filtering added. Terminals to rear panel 
connector directly.   That is an endorsement of at least that model in my opinion.

The online reviews are good, noting only high fan noise, which can be fixed by replacing the fan with a Vantac Stealth.  But I haven’t seen anything about RFI.
