30 Watts PoE + Injector.Converts a non-PoE 100Mbps port to a PoE or PoE + 100Mbps port and network a PoE device located up to 100 meters (328 ft.) Away. If you have a PoE + (802.3at) or PoE (802.3at ) standard device, and need to use PoE technology to provide it with both network and power, this PoE adapter is your best choice. Auto-sensing technology delivers up to 30 Watts to an 802.3at PoE + device with backwards compatibility for 802.3af PoE (15.4 Watts) devices. It can detect POE equipment and non-POE equipment. For POE equipment that meets 802.3at or 802.3af standards , it will communicate with the equipment and provide appropriate power. For non-standard POE equipment, it will automatically detect and actively power off to protect the equipment. This is very smart and safe. 100Mbps Ethernet Speed.
