16 Port Gigabit 802.3at On-Demand PoE Injector with 56V240W Power Supply

SKU AT-16-56v240w
Sold out

16 Port Active PoE Injector for High Powered Devices like Cisco WiFi APs

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
  • Two UL/FCC/DoE Certified 56 Volt 120 Watt power supplies included for a total of 240 watts total budget
  • 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
  • Are you planning to make a 60W per port model? For 802.3bt/ut? Use case is intelligent LED lighting.

    Our WT-GPOE-16-AB will do 60 watts. It is a passive device which would work well with LED Lighting. Please contact our tech support team to offer the best solution for your setup. Once the bt standard is issued sometime later this year, we do have plans to manufacture an 802.3bt device. 

  • This unit supports 30W per port, correct?

    Correct. The maximum a powered device can pull from this injector is actually closer to 36 watts per port, taking into consideration the limit of 240watts total.

  • I saw at on the injector, with two power supplies ... But If we have at AND af components to power ... is it OK to use it ? Thank you Pascal

    Yes, our AT injectors are backwards compatible to power AF devices.

  • Is it possible to use two different voltages for the PSUs? A 24v for one "half" and a 48v for the other "half"?

    No, our injectors are not designed to accept dual voltages. The AT-16 is compatible with an input voltage of 44-56V but if two power supplies are used, they should be the same output power.

  • Does each power supply manage 8 ports? (PSU1 ports 1-8, PSU2 ports 9-16). If so we will configure in a balanced architecture.

    One power supply can power all 16 ports, but using two can either increase your power budget, or act as a redundant power supply. Using both power supplies offers a power budget of 240W.
