The Poe injector allows power to be supplied to a 10/100/1000mbps network over CAT5e , CAT6 or CAT6A Ethernet network cable. The power source can be any power supply from 10V to 30V , and the injector's output voltage is 48V . The poe adapter can be powered from the DC jack 5.5/2.1 mm connector - or from the pins of the RJ45 plug - 4.5 (plus) and 7.8 - (minus). With a poe injector, a battery (12V or 24V) or passive PoE (10V-30V) can be used to power a 48V device.
When connecting the power supply to the DC jack 2.1mm input - the power will be isolated from the male RJ-45 connector - so it can be connected to a switch or router. The 48V output voltage is delivered to the 3.6 (plus) and 1.2 - (minus) pins of the female RJ-45 jack to power any 802.3af device. There is an exchange of both the voltage with which the receiving device is powered and the pins on which power over ethernet operates
