240VAC to 48VDC PoE – Gigabit Passive PoE Injector & Surge Protector – AC-DC

50,00 35,00

AC-DC Passive Power over Ethernet Injector & Surge Protector

Key Features

  • Drop in replacement for Ubiquiti PoE
  • 10/100/GigE
  • 100-240VAC systems
  • 48VDC 0.5A 802.3af Mode B PoE output (passive)
  • Dual block inputs for connecting 2 power sources
  • Short Circuit, Over Current and Reverse/Over Voltage protection
  • High temperature operation
  • Supplied with 3-pin “clover” 240VAC Australian power plug
  • Ideal for Ubiquiti devices.




  • This series of AC to DC converters is a highly reliable for those requiring 48VDC power over Ethernet voltage from a mains AC system
  • They have an integrated POE injector to apply 48VDC to Ethernet cable in 802.3af Mode B (Passive) PoE pin arrangement (no handshake)
  • The SFTP or FTP shielded Ethernet cables provide inbuilt ESD and surge protection by detecting and arresting charge on the cables GND terminal
  • 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
  • We recommend these hardened, industrial grade PoE injectors for all harsh environments, and remote/regional links.
