The TP-DCDC-1248GD Gigabit DC to DC converters offered by Tycon Power® is a low-cost and high-efficiency solution for those requiring IEEE802.3af or Passive Power over Ethernet from a 12VDC or 24VDC or 48VDC voltage source like a battery system or vehicle. It has an integrated POE injector to apply the power and data output to the CAT5 Ethernet cable. The output voltage is regulated and protected. It has two isolated inputs for connecting 2 power sources, like a primary and backup power source. A metal enclosure model is available for industrial applications.
It accepts gigabit data-in to a shielded RJ45 Jack and provides gigabit data-out and PoE power on the shielded RJ45 output jack. They work by supplying power on Ethernet pins 4,5(V+) and 7,8(V-). They have various protections for surge, short circuit and overload. The units have power outputs up to 24W.
