Περιγραφή
POE-BOX4-G is a passive Gigabit PoE injector suitable for powering up to 4 devices. Connectors marked “LAN” connect Ethernet ports without power supply eg switch, to the opposite side of “POE” connect devices using passive PoE. For powering PoE injector uses two pairs of Ethernet cable: 4,5 (positive pole) and 7,8 (negative pole). The power supply is connected via a standard 2.1/5.5mm power connector. The passive PoE injector can be used in the range of 12 to 57V DC with a max. current of 1000mA / port.
