Active PoE means the right power at the right time. An active PoE injector negotiates with the powered device to deliver the voltage needed, so there are no concerns about accidentally burning out lower powered or non-PoE devices. Power is only added to the data cable when an 802.3af or 802.3at device is connected.

Product Features:

  • Instantly upgrade your network switch to PoE+ for 802.3at devices like VOIP phones, WiFi Access Points, Cameras and More
  • Active negotiation protects non-PoE devices
  • Mode A power delivery (pins 1,2- / 3,6+)
  • Includes a 56 volt, 120 watt power supply
  • Shielded RJ45 ports
  • 650mA self-resetting fuse / 30 watts per port
  • Supports 8 x 802.3af devices (up to 15 watts each) or 4 x 802.3at devices (up to 30 watts each)

Ask a Question
  • Will the power draw by this unit scale with the number of ports in use? So .. if I buy the 8-port variant instead of 4-port, but don't use the extra 4 ports yet, will the power actually used be roughly the same?

    The amount of wattage consumed is determined by the device. For example, if your device consumes 30 watts each x 4 devices (120watts), you could select 4 ports or 8 ports. The WT-AT-8 offers a pheonix connector, the WT-AT-4 does not. If you would like extra ports to expand you can always purchase a larger wattage power supply to use with this PoE injector. Just keep in mind that our ports are limited to a .650 Amp power draw. If you have more questions feel free to call us 512-479-0317 or email

  • I know your multiport POE injectors support standard POE, however do you have any that support POE+? We have a new camera system in which some cameras are POE and a couple are POE+. Do you have something that will support both?

    Since you're looking at the WT-AT-8, you're looking at the right product.  It can support both PoE and PoE+ (IEEE 802.3at).  So this one will work for your application. 

  • What is the PF on your Power supply? Can you also supply hardwire 48vdc to this unit?

    The line regulation is .5% and the load regulation is 1% (both + or -).  Yes, you can hardwire a power supply to the AT-8 injector via the 4 pin female Phoenix Connector.  If you are looking to double the power supply, we do recommend that you use the same voltage and wattage for proper load balancing.

  • Can this Model(WT-AT-8-56V120W) power AT and AF devices simultaneously? I need help identifying a model that will power and data a Blackmagic HyperDeck Studio Mini and a PTZOptics PT12X-NDI-ZCAM. Thank you!

    Yes, our 802.3at injectors will provide data to devices that are either 802.3af or and can do so simultaneously.

  • Will these work for Ubiquity AirFiber AF-5

    Thank you for your inquiry, we are sending a response to you from in an additional thread providing more information about making Ubiquiti AF PoE. 

  • Can this be used to power a Ubiquity unifi AC LR ( as well as a mix of 802.3at and 802.3af devices?

    I would recommend WT-AT-8-48V120W to be compatible with both 802.3af and 802.3at devices, since 802.3af is not compatible with 56 volts and WT-AT-8-56V120W.
