100-220V, 50-60Hz, 52V DC, maximum speed: 1000Mbps, transmission distance: 100m. The POEINJ-30W is a Gigabit PoE (Power over Ethernet) device with a single port and two RJ45 ports. One port is used for Ethernet data input, while the other port is used for integrated data and power output. Since the power supply itself does not have data switching functionality, it must work in conjunction with a network switch. It combines the data from the network switch with the power supply and transmits both data and power over the network cable to the remote powered device. This can resolve layout constraints due to electrical supply lines. The device can provide PoE power for Ethernet devices that comply with the international standard IEEE802.3af/at, such as routers, switches, wireless APs, VoIP phones, industrial network terminals, and network cameras. It offers efficient engineering 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.
