The Gigabit compatible TP-DCDC-1256G-VHP and TP-DCDC1256GD-VHP are special very high power DC to DC converters / POE inserters designed especially for higher power PoE applications. The TP-DCDC-1256GD-VHP has dual channel 802.3at output for PTZ Cameras like the Axis 6000 series. The TP-DCDC-1256G-VHP is designed for those High Power Passive PoE devices like Ubiquiti airFiber. The unique POE inserter supplies 56VDC POE power on all 8 Ethernet wires (4 Pair) with a total output of up to 70W.The wide input voltage range (10VDC to 60VDC) makes these units universal in battery powered applications. The units input and output is isolated so they work in a negative ground of positive ground system. They have two DC inputs for connecting 2 power sources, like a primary and backup power source. They have various protections for surge, short circuit and overload. The units come complete with a DIN Rail mounting kit for mounting to a standard DIN rail.
