The TP-DCDC-1248GAD Gigabit DC to DC converters / PoE Injectors offered by Tycon Power® are a low cost and high efficiency solution for those requiring IEEE802.3af Power over Ethernet from a 12VDC or 24VDC voltage source like a battery system or vehicle. They have an integrated Mode A PoE injector to apply the power and data output to the CAT5 Ethernet cable. The output voltage is regulated and protected. 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 gigabit data-in to a shielded RJ45 Jack and provide gigabit data-out and PoE power on the shielded RJ45 output jack. They work by supplying power on Ethernet pins 1,2(V+) and 3,6(V-). They have various protections for surge, short circuit and overload. The units have power outputs up to 17W.
