DC-DC Passive Power over Ethernet Injector

  • Suits 48V solar power systems
  • 36-72VDC systems
  • 24VDC 1.25A 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
  • Ideal for Ubiquiti devices.

This series of DC to DC converters are a low cost and high reliability solution for those requiring 24VDC Power over Ethernet voltage from a 48V battery system. They have an integrated POE injector to apply 24VDC to Ethernet cable in 802.3af Mode B (Passive) PoE pin arrangement (no handshake). They have two isolated inputs for connecting 2 power sources, like a primary and backup power source. A metal enclosure model is available for industrial applications. They accept data-in to a shielded RJ45 Jack and provide data-out and POE power on the shielded RJ45 output jack. They work by supplying power on the unused Ethernet pins 4,5(V+) and 7,8(V-).
