Description

The TP-DCDC Gigabit Series of DC to DC converters offered by Tycon Power® are 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. They have an integrated 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 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.
