Description
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 and IEEE802.3at Power Over Ethernet from a 12VDC or 24VDC or
48VDC voltage source like a battery system or vehicle. They have an integrated POE injector to apply the 802.3af or
802.3at output to the CAT5 Ethernet cable. The output voltage is regulated 48VDC-56VDC. 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 up to 35W.

If the remote device does not support 802.3af or 802.3at power over Ethernet, a TP-POE-1224 802.3xx converter is
available to change the POE output to passive POE with 12V or 24VDC POE output.
