PoE Injector. 802.3af/at PoE 30 Watt. Power over Ethernet per port: 30 W. RJ-45 speed: 1 Gbit/s, 10/100/1000 Mbit/s. Reduces infrastructure costs by simultaneously transmitting data and power over an Ethernet cable. Automatically detects and delivers the exact power needed to meet the device's requirements. The wall-mounted and desktop design is suitable for most installation scenarios. Plug & Play installation, requires no configuration, integrated power supply. Power over Ethernet (PoE). With Power over Ethernet, you can power compatible devices through the network cable. This significantly reduces cabling effort for end devices such as wireless access points, IP phones, and IP cameras, while also providing high flexibility in device placement. 802.3at PoE. The IEEE 802.3at standard provides a maximum of 25.4 watts of power per PoE port with a voltage of up to 50 volts. The standard assumes that after line losses, 21.90 watts of usable power remain or may be drawn to avoid exceeding the maximum power output. A Cat5e/6 cable with a maximum length of 100 m is recommended for PoE.
