Yep. Not really reverse, it's still input -> output. Both the input and
output are floating. Just wire - to - and + to +. Yes, your "-48" from
the rectifier goes on the negative terminal of the input on the RSD.
And you can get either the RSD-200C-48 or 300C-48. 200 or 300W as the
names suggest. 38 to 62VDC input (IIRC), regulated 48v output.

Is this doable in reverse? We have a -48v UPS/battery bank, want to
convert to traditional 48v on the load side? Looking at putting a
Netonix at this site.

Mean Well RSD200C-48 will work just fine. Put it between your 48v UPS
load side and -48 gear. The output of the RSD is floating and you
should have no problem tying the + side to ground.

I have a site that I am converting to DC from AC. All of the gear
powers at traditional 48v with a negative ground. I have a PTP800
though that I am told is -48v (ground tied to positive). How do I
get -48v for the PTP800?
The site has a NewMar DIN-UPS 48-10. It states that the outputs are
isolated (it has 2) but I do not think they are isolated from each
other, just from ground. To tell you the truth I am lost. I was
thinking maybe a DC to DC converter of some sort.
Thank you,
