How about a dc-dc poe/SS that takes –48 and converts to +48, 24v etc ?

Me too...
So, what appetite is there for an inline POE regulator that would convert 48 to 
24?

ugh... I keep forgetting to use reply-to-all...

Not every single UBNT radio... all the airfibers will happily take 48v. 
Mikrotik is finally starting to make most of the new stuff handle 48v 
(including the PowerBox Pro), but yeah. UBNT is the reason I still have to use 
24v on most of our towers... they make a converter you can stick on in line 
with the radios, but that's kind of a pain if you have more than one or two, 
and it's an extra part to fail.

I promise life will be easier if you just use 48V.  :)

I'm trying to use a Powerbox Pro to power up two epmp APs.  The 5 GHz is just 
fine but the 2 GHz is saying current too low.  Both ports are getting 23 volts 
and the cables are <10 feet (from the Powerbox Pro).

Does anyone know if the 2ghz requires more voltage possibly?

Spec sheet does say 23 volts min but it's weird one powers (5 ghz) and the 
other doesn't.
