The DDR series (Meanwell DIN mount DC-DC) are also good, like the RSD, but in a DIN mount form factor.  Jesse DuPont Owner / Network Arch

even every "-48" rectifier I've encountered before wasn't chassis referenced, so we use those for +48 as well Just wanted to put that out there that many things don't care. Mikrotik 1072 routers w/ '-48' power supplies their support swore they aren't for +48, but work fine. On Fri, Jul 2, 2021

I was gonna say the same thing.  RSD also doesn't have a cooling fanone less thing to fail. In either case get a few #6 bolts (or similar size metric) and you can mount them to a 1U blank. On 7/2/2021 1:54 PM, Josh Baird wrote: Do not use the "SD" series.  Look for the RSD series instead

Do not use the "SD" series. Look for the RSD series instead. The SD series has issues with current inrush. On Fri, Jul 2, 2021 at 1:52 PM castarritt wrote: > Thanks for the info. I did check the chassis ground vs dc return on my > dragonwave radios, and they weren't bonded. I'll check with d

Thanks for the info. I did check the chassis ground vs dc return on my dragonwave radios, and they weren't bonded. I'll check with dwave to see if they are cool with 0v input and +48v return. If so, we will buy +48v DC systems in the future. For the -48v ICT we already have, I was looking at th

Yes you can put an isolated 48v dc to DC supply to isolate -48 from +48 (a meanwell brand would work) needs to be an isolated converter Also fyi that most of the '-48' equipment I've tested hasn't had a chassis reference to either of the DC input terminals, so thus far I've ran as +48 on everythin
