DC-DC Gigabit Passive Power over Ethernet Injector

Formerly MIT-45G-24

Key Features

• Suits solar power systems

• 10/100/GigE

• 9-36VDC systems

• 24VDC 0.8A 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.

Usage

• This series of DC to DC converters are low cost and highly reliable for those requiring 24VDC Gigabit Power over Ethernet voltage from a 12V 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-).
