The POEINJ-60W is a single-port Gigabit PoE (Power over Ethernet) device featuring two RJ45 ports: one for Ethernet data input and another for integrated data and power supply output. Since the power supply does not include a data switch function, it must work in conjunction with a network switch. This device combines the data from the network switch with the power supply and transmits both to the remote powered terminal through the network cable. It addresses layout restrictions caused by engineering power lines. The device can provide PoE power supply to Ethernet devices that conform to the IEEE 802.3af/at PoE++ international standard, including routers, switches, wireless access points, VoIP phones, industrial network terminals, and network cameras. It offers efficient engineering solutions for locations where power is unavailable at the remote end or where using Ethernet cable power increases system reliability and simplifies equipment installation.
