Gigabit 4 port PoE Injector Steps up 12 Volt to 24 Volt


Gigabit, Mode B 4 Port Injector with an integrated 12 volt to 24 volt step up Adapter

Proof of Concept: This Beta 4 port injector targets PoE users requiring a 12 volt power supply from batteries either for solar or battery back-up application.  Currently the beta product has two components, the first to convert 12 to 24 volts at 24 watts, the second the 4 port Gigabit Mode B passive injector with compatibility for Ubiquiti, Mikrotik, or any 24 volt passive backhaul device.  The final product will be a single injector that fits into the housing of the GPOE-4B injector now.

Why 24 Volt Passive instead of 12 Volt?  Backhaul and infrastructure, for example those made by Ubiquiti and Mikrotik, use 24 volt PoE because of its low cost to implement with the ability to transmit well over distance.  While you can put 12 volts onto an ethernet cable, watch our video on why 12 volt PoE is a bad idea.  Then take a spin on our PoE calculator to see the difference between 12 volt and 24 volt PoE.

What if I need 12 volts to Power my Device?  The WS-POE-12v12w splitter will step down 24 volt Passive PoE regardless of the voltage drop to a regulated 12 volt power supply and separate data line.  See our full line of PoE-12v kits.
