100-220V, 50-60Hz, 52V DC, Maximum speed rate: 1000Mbps, Transmission distance: 100m. The POEINJ-30W is a single-port Gigabit PoE (Power over Ethernet) device with two RJ45 ports, one port for the Ethernet data input and another port for the integrated data and power supply output. Since the power supply itself does not have the data switch function, it needs to work together with a network switch. It mixes the data of the network switch with the power supply and transmits the data and the power supply to the remote powered terminal through the network cable. This can solve the layout restrictions due to the engineering power line. The device can provide PoE power supply to those Ethernet devices conforming to the IEEE802.3af/at international standard, such as routers, switches, wireless APs, VoIP phones, industrial network terminals, and network cameras. It provides 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.
