Extralink 1 Port PoE Inverter

Extralink poe injector

The Poe injector allows power to be supplied to a 10/100/1000mbps network over a CAT5e, CAT6 or CAT6A Ethernet 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 - or from the RJ45 plug pins - 4.5 + (plus) and 7.8 - (minus). With the poe injector, a battery (12V or 24V) or passive PoE (10V-30V) can be used to power a 48V device.

When power is connected to the 2.1mm DC jack input - the power will be isolated from the male RJ-45 connector - so it can be connected to a switch or router. A 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 supplied and the pins on which the power over ethernet operates.
