AC-DC Passive Power over Ethernet Injector for Ubiquiti AirFiber


Key Features


  • Drop-in industrial replacement for Ubiquiti PoE

  • 10/100/GigE

  • 100-240VAC systems

  • 56VDC 1.79A PoE output (all 8 pairs)

  • Short Circuit, Over Current and Reverse/Over Voltage Protection

  • High Temperature Operation

  • DIN Rail mountable

  • Supplied with 240VAC Australian power plug.




  • This series of AC to DC converters are a low cost and high reliability solution for those requiring 56VDC Power over Ethernet voltage from a mains AC system

  • They have an integrated POE injector to apply 56VDC to Ethernet cable on all 8 pairs

  • AirFiber radios require 50VDC 1.2A however a 56VDC injector operates perfectly fine within the radios tolerances (42-58VDC)

  • When using SFTP or FTP shielded Ethernet cables this unit provides inbuilt ESD and surge protection by detecting and arresting charge on the cables GND terminal

  • These units are recommended as a drop-in replacement for standard Ubiquiti PoE injectors in environments where Ubiquiti PoE failure (extremely common) will result in impact to business or critical systems

  • These hardened, industrial grade PoE injectors are strongly recommended for all harsh environment, and remote/regional links.
