+1 Meanwell RSD will work.  You can verify with your multimeter that it has no connection between DC and ground, but I guarantee it doesn't. On 6/25/2020 9:35 AM, Josh Baird wrote: The RSD is isolated.  Not sure if all DCDC converters are, but I know the RSD is. You are right - the WTM4100

The RSD is isolated. Not sure if all DCDC converters are, but I know the RSD is. You are right - the WTM4100 is different after looking at the spec sheet: Input voltage: -20 to -57V (WTM4100/ 4200 13-42 GHz) Input voltage: -40 to -57V (WTM4200 5-11 GHz) I only have experience with the WTM4200 (

Thanks Josh I do have an RSD handy but it doesn't say isolated and some others do. Is a Dcdc converter isolated by nature? The specs say they will take 24v also in the dc port, would I still need the dcdc? The sales guy told me they are positive ground. Thanks again Rhys Sent from my iPhon

Yeah - you will need -/+48VDC for the Aviat radio. They are floating, so they don't care about -/+. I would stick a Meanwell RSD in line to convert your -24VDC to 48VDC and be done with it. On Thu, Jun 25, 2020 at 9:15 AM Rhys Cuff (Speedweb Internet) via AF < af@af.afmug.com> wrote: > Hi Guys
