Yup. Just use a RSD200C-48 and not worry about it.

You need an isolated DC-DC converter between your +48V and -48V. Look
into the Meanwell RSD series (not the SD).
Specifically, take a look at the RSD-200C.

I have a terrible time wrapping my head around -48vdc. I'm hoping
you guys can help. I've got a Cambium PTP820S that I'm going to
be putting on the same tower with several Mimosa B5s. The 820S is
apparently -48vdc, while it appears the Mimosa is +48vdc. I'd
like to power both with a Meanwell AD-155C with a 48v battery
string. So... what are my implications here? Will having both
-48 and +48 radios on the same tower, coming from the same power
supply end up shorting through the tower? What's the best way to
do this short of using two separate power supplies and battery
strings?
Thanks!
