I think I used an isolation transformer that limited the energy to 45 VA or 
something like that.

Oh, that could be fun...  I imagine that had a pretty small fuse on it...????

  I was hoping not to.  Had to add a repeater to an existing install for the 
customer to pickup another building.  Cat5 goes through an underground conduit 
and then 150' through a shop building.

    Powering the Powerbox via a dc cable isn't an option?

      I'm trying to run a Mikrotik Powerbox via POE to power a Force300 and an 
      EPMP1000 GPS Radio.  Given the length of the cable run, the 24V supply 
      that comes with the Mikrotik is only 20V at the device, and won't power 
      up the 1000 AP.  It's all running with the Cambium 30V POE injector from 
      the F300, but I'm afraid if it reboots in the cold, and has to run the 
      heaters it won't be enough juice to power up.  I can find 24V POE's all 
      day long, but 30V are hard.

      I could use a Meanwell PS (MDR seires Spec sheet says it can be adjusted 
      to 30V max)  with a MCT POE Injector, but I'm hoping to find something 
      cleaner, since the POE is just sitting on the floor in an office now.
