Re: Fw: Neat Power over Ethernet Injector Cables

[Kevin Hawkins <lists@xxxxxxxxxxxxxxxxx>]

The issue aside from max current will be the voltage drop along the
cables caused by that current. Ironically particularly so for better
regulated power supplies - where the powered device itself includes
little or no onbard regulation.  PSU's providing 5V regulated are likely
to be the ones that might suffer most.
