Anyone familiar with the Sorenson DCS 55-55 rack mount power supply? Are they RFI clean? I am thinking of replacing an Astron VS-50M with a used one as the Sorenson is 0-55VDC & 0-55A and has digital readouts with additional data. WDYT? -- Thanks! & 73, doc, KD4E Projects: ham-macguyver.bibleseven.com Personal: bibleseven.com/kd4e.html
