be careful POE can be anything up to 48 volts. Unless you control the input voltage. I suggest using a DC-DC converter with a larger input voltage.

  It is passive POE, you need to supply your own input as it won't work with a POE switch or anything like that.

    There are some switches that supply passive PoE, such as many of Ubiquiti's products.

      Sure, but you have to explicitly enable it. When would you not have control over the input?

  Regular PoE can in some cases get as high as 56 volts... Some PD equipment is overspec'd to deal with regulation issues on PSEs.
