DC-DC Gigabit Passive Power over Ethernet Injector

Key Features

• Suits solar power systems

• 40-60VDC systems

• 10/100/GigE

• 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

• This series of DC to DC converters are a low cost and high reliability solution for those requiring 48VDC Gigabit Power over Ethernet voltage from a 48-60V 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-).
