Tycon Power Systems


Tycon 36-72VDC IN. 56V 70W 4 pair Passive PoE OUT. DC to DC Converter and Gigabit Passive PoE Injector



The TP-DCDC-4856G-VHP is a very high power DC to DC converter / passive POE inserter designed for Ubiquiti airFiber antennas and also various outdoor PTZ security cameras. The DCDC converter supplies 70W passive POE power on all 8 Ethernet wires.

They have two common (-) and two (+) for connecting 2 power sources, such as a primary with a backup power source. They have various protections for surge, short circuit and overload. The input and output are isolated.
