The TP-POE-2456D is a unique Power Over Ethernet adapter which converts a 24VDC passive POE input to an802.3af/at 56VDC POE output.
The only connections required are CAT5/6 cables. The IEEE 802.3af/at compliant POEoutput is capable of up to 35W power output.
The POE input is 22V to 36VDC passive POE so the TP-POE-2456D is perfect for running IP POE Cameras or other POE devices from passive POE switches like the Tycon TP-SW5G-NC TP-SW8-NC or Ubiquiti TOUGHSwitch™.
The units supply power to the remote device on the unused Ethernet pins 4,5(V+) and 7,8(V-). The Ethernet spec supports distances up to 100m (328 feet).
They have various protections for surge, short circuit, overload and overvoltage.
