4 port 48v60w 802.3af poe injector


4 Port Gigabit 802.3af auto negotiating PoE+ Injector. Includes 48 volt 60 watt power supply.


The WT-AT-4 802.3at injector for 4 gigabit devices provides up to 25 watts per port from one supply. These devices provide power on the Ether data pin 1 and 2, and 3 and 6. The voltage is supplied to each port only after negotiation, and no power is supplied to non-PoE devices.

While our passive PoE injectors can provide 60 watts of “always on” Power over Ethernet, the WT-AT-4 negotiates with 802.3af and 802.3at devices to signal that ample power is available. Many Cisco, Meraki, Aruba and high end IP Cameras disable some features unless an 802.3at injector is used. For IP phone applications, the WT-AT-4 provides power only to PoE devices, it is perfect for offices where users could unknowingly connect non-PoE devices like laptops or copy machines to passive PoE. Total power options of 30 to 120 watts are available in the wall mount style, more in our rack mount versions.
