100-220V, 50-60Hz, 48V DC, Maximum speed rate: 1000Mbps, Transmission distance: 100m. The POEINJ-15W is a single-port Gigabit PoE (Power over Ethernet) device with two RJ45 ports: one port for Ethernet data input and another port for integrated data and power supply output. Since the power supply itself does not have data switch functionality, it needs to work together with a network switch. It combines the data from the network switch with the power supply and transmits both to the remote powered terminal through the network cable. This solution addresses layout restrictions due to engineering power lines. The device can provide PoE power supply to Ethernet devices conforming to the IEEE802.3af international standard, such as routers, switches, wireless access points, VoIP phones, industrial network terminals, and network cameras. It offers efficient engineering solutions for locations where power is not available at the remote end or where the use of Ethernet cable power increases system reliability and simplifies equipment installation.
