This POE injector is a passive POE system. It uses the RJ45 pins 1,2,3,6 for data and pins 4,5,7,8 for power. The 48V on pins 4,5,7,8 is always there, no way to turn it off. There is no "negotiation" like in a true active 802.3af.
The splitter is also passive, what I mean by that is the data that comes in on pins 1,2,3,6 is simply passed thru to the output, like what a $3 RJ45 F-F coupler does. It does not receive the data and then recreate (re-transmit) the data again like what a switch does. Therefore this can't be used to extend an ethernet cable run beyond the 100 meter limit.
The 48V power received on pins 4,5,7,8 is indeed then converted down to 5,9 or 12V for use by the end device,
So if you need to get power and data to a single device, and that device is less than 100 meters away, and the device needs 5,9 or 12V then this should work for you.
