The POEINJ-60W is a Gigabit PoE device with a single port and two RJ45 connectors: one for Ethernet data transmission and one for integrated data and power output. Since the power supply does not include a switch function for data, it must be operated in conjunction with a network switch. This device combines data from the network switch with power and transmits both over the network cable to the remote powered terminal. It resolves layout constraints caused by electrical wiring. The device can provide PoE power for Ethernet devices that comply with the international standard IEEE 802.3af/at PoE++, including routers, switches, wireless access points, VoIP phones, industrial network participants, and network cameras. It offers efficient technical solutions for locations where no power supply is available at the remote end or where the use of Ethernet cable power increases system reliability and simplifies device installation.
