DC-DC Passive Power over Ethernet Injector

Formely MIT-14-48

Key Features

 

  • Suits solar power systems

  • 9-36VDC systems

  • 48VDC 0.5A Passive PoE output (802.3af Mode B)

  • Dual block inputs for connecting 2 power sources

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

  • High Temperature Operation

  • Ideal for Ubiquiti 48VDC devices.

 

Usage

 

  • MSTronic's series of DC to DC converters are a low cost and high reliability solution for those requiring 48VDC Power over Ethernet voltage from a 12, 18, or 24V battery system

  • They have an integrated POE injector to apply 48VDC 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-).
