How to feed a B24 with 24Vdc power source

Hi need advise on how to power up a B24 Mimosa radio in 24Vdc sites.

What DC to DC converter?

We have used Tycon 24 to 48 PoE injectors before with good results. Personally I ditched them because I prefer having a PoE switch powering things. Netonix has several switches that could work.
