8 Port Active Gigabit Mode A PoE Injector (Power Supply Not Included)

Sold out

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+)
  • Input Voltage range 44-57V DC (Power supply sold separately)
  • 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
  • Is the WT-AT-8 gigabit PoE injector also compatible with 10/100 MB devices

    Yes, the WT-AT-8 is able to support 10/100/1000 Data speeds. If your router or switch is only 10/100 capable, you will only have 10/100 on the data output. 

  • What are the physical dimensions of the WT-AT-8?

    You can always find the product dimensions on the "Tech Info" tab just below the images.  However, if you need more precise product dimension information, like a drawing, you can contact

  • What power supply is recommended for use with this?

    We recommend our 56 volt 120watt power supply, search for WT-AT-8-56V120W

  • Will this device function normally in POE af mode if only supplied with 48 volts? Can it handle both at and af devices at the same time if powered by 56 volts?

    This is an active 802.3at injector, so it will do an auto-negotiation with the end device to see if it accepts POE. It does not have an 802.3af 'mode' but it will work with 802.3af devices if used with a 48 volt power supply.
