Product Details

Altronix Tango8A PoE Driven Power Supply with Access Power Controller converts an IEEE802.3bt (4PPoE) input into eight (8) regulated 24VDC and/or 12VDC outputs up to 65W. It eliminates the need for a high voltage inside of an enclosure. Tango8A is designed to support a single 12VDC LiFePO4 (Lithium Iron Phosphate) battery for 12VDC and 24VDC backup.


Ethernet Input

  • 802.3bt PoE up to 90W (or 802.3 at up to 30W or 802.3af up to 15W)

Power Output (when using 802.3bt 90W)

  • 12VDC up to 5.4A (65W) and/or 24VDC up to 2.7A (65W).
  • Combined output not to exceed 65W
  • When charging batteries: 12VDC up to 4.6A (55W) and/or 24VDC up to 2.3A (55W), Combined output not to exceed 55W.

Ethernet Output

  • Pass-through Ethernet Port (data only).

Battery Charging Circuit

  • 12VDC battery charger for Lithium Iron Phosphate Battery (LiFePO4 only).
  • Unique technology allows for single battery to backup
  • 12VDC and/or 24VDC systems


  • Loss of PoE Input
  • Battery Supervision

Indicators (LED)

  • Input - Indicates input voltage is present
  • Output - Indicates normal operating condition
  • PoE Type - PoE Class Indicator
  • Supervision - PoE Fail or BAT Fail
