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 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-).
