AC-DC Passive Power over Ethernet Injector & Surge Protector

  • 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 are a high reliability solution 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). 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.
