The TP-DCDC Gigabit Series of DC to DC converters offered by Tycon Power Systems 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 POE injector to apply the 802.3af output to the CAT5 Ethernet cable. The output voltage is regulated 48VDC. 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 the unused Ethernet pins 4,5(V+) and 7,8(V-). They have various protections for surge, short circuit and overload. The units have power outputs of 17W.
