AC-DC Passive Power over Ethernet Injector for Ubiquiti AirFiber

  • 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.
