DC-DC Gigabit 802.3at PoE+ Power over Ethernet Injector

Formerly MIT-55G-1256D


Key Features


  • Suits solar power systems

  • 10/100/GigE RJ45

  • 10-15VDC systems

  • 56VDC 625mA (35W) 802.3at Compliant

  • Dual block inputs for connecting 2 power sources

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

  • High Temperature Operation.




  • MSTronic's series of DC to DC converters are a low cost and high reliability solution for those requiring 802.3at Power over Ethernet voltage from a 12V battery system

  • They have an integrated POE injector to apply 56VDC to Ethernet cable in 802.3at PoE pin arrangement

  • 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-).
