InstantOn PoE Injector. 802.3af PoE 15.3 Watt. Maximum PoE power per port: 15.4 W. RJ-45 speed: 10/100/1000 Mbit/s. Compatible with the InstantOn AP22 Access Point. The IEEE 802.3af standard provides a maximum of 15.4 Watts of power on each PoE port with a voltage of up to 48 volts. The standard assumes that after line losses, 12.95 Watts of usable power remain to avoid exceeding the maximum power output. Power over Ethernet (PoE) allows compatible devices to be powered through the network cable. This particularly reduces cabling efforts for end devices such as wireless access points, IP phones, and IP cameras, enabling high flexibility in the placement of these devices.
