Extralink 1 Port PoE Inverter

What is a PoE injector?

Poe injector enables power supply to a 10/100/1000mbps network on the network cable Ethernet CAT5e, CAT6 or CAT6A. The power source can be any power supply from 10 V To 30 V, a the injector output voltage is 48V. The Poe adapter can be powered from the connector of the DC jack 5.5/2.1 mm - or from the pins of the plug RJ45 - 4.5 + (plus) and 7.8 - (minus). Thanks to the poe injector, a battery (12V or 24V) or passive PoE (10V-30V) can be used to power the device. 48V.

If the power supply is connected to the input DC jack 2.1mm - the power supply will be isolated from the male connector RJ-45 - so they can be connected to a switch or router. Output voltage 48V is supplied on pins 3.6 + (plus) and 1.2 - (minus) of the RJ-45 female socket to supply power to any device 802.3af. 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.
