16 Port Active PoE Injector for High Powered Devices


Active PoE Injector for High Powered Devices Like Cisco WiFi Access Points (Power Supply Sold Separately)

Power IP cameras, desktop phones, WiFi access points, and more. This 802.3af/at compliant Power over Ethernet (PoE) injector takes power from the included 56 volt DC power supplies and adds it to a Cat5, Cat5e or Cat6 Ethernet data cable to power your PoE devices.

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 any network switch or router to Gigabit Power over Ethernet
  • Use to power IEEE 802.3at (PoE+) devices like, WiFi Access Points and Cameras
  • Compatible with Active Cisco and Meraki WiFi Access Points and other devices - Please check manufacturer specifications for compatibility
  • Active auto-negotiation feature offers power on demand and protects non-PoE devices - power remains OFF until a compatible device is connected
  • Input voltage range 44-56 Volts DC
  • Two 5.5 x 2.1 mm DC or two Phoenix connector input options
  • 30 watt per port output for PoE+ devices
  • Designed to fit in a 1U Rackmout Space - Select the "With Power Supply Trays Option" to fit the injector and power supplies in 1U space*

    Ask a Question
    • I have 8-12 30 watt devises, which injector is needed? which power supply also?

      You could use our WS-GPOE-16A-56V240W injector kit. This will power up to 8 POE devices with the included power supply. 

    • what power supply do I need to buy for this unit?

      It depends on what you need to power with it.  You will definitely need either a 48 volt or 56 volt power supply, as these fit into the IEEE 802.3at standard.  Now, the next question is how many devices are your powering and at what level.  For example, if you have 10 x normal POE devices that you want to power at 15 watts each and one 30 watt device, then you should go with 2 x WS-PS-56v120w power supplies, which we sell as a kit.  This will always be a safe bet.

      If you'd like assistance in looking up your devices and determining the best power supply, you can talk to one of our Austin based POE experts at 512-479-0317.

    • Does this device autonegotiate or is it passive?

      This autonegotiates on all 16 ports.

    • From the documentation, it appears that the device only has a total power budget of 240W. Does this mean that when using devices on the AT standard that only half of the ports (8) can be used (assuming full 30W draw) Does adding the second Power Supply increase the budget to 480 to ensure all 16 ports can be used at 30W?

      Great inquiry! The kit options we offer are only budgeted with 240 watts (2 x PS-56v120w). However, each port has a fuse limit of 650 mA that it can support. If you need a budget higher than 240 watts, you can use the phoenix connectors on the back of the injector to direct wire a higher-budget power supply.

    • For the WT-AT-16 is specifies "Gigabit" as the data rate. The switch we use supports 10/100/1000 Mbps auto-neg. Is auto-neg @ 100Mbps supported?

      Yes, the AT-16 injector supports both gigabit data speed and auto-negotiation of power.

    • The WT-AT-16 has two power inputs. How do those work? Redundant or does on power ports 1-8 and the other 9-16?

      The AT-16 allows for 2 power supplies to double the overall wattage as well as be a redundant power supply should the need arise.
