The TP-POE-48D offered by Tycon Power (PoE Injector) is are quality midspan power source for years of reliable operation even in the toughest conditions. They accept data-in to a shielded RJ45 Jack and provide surge-protected data-out and power on the shielded RJ45 output jack. They work by supplying power to the remote device on the unused Ethernet pins 4,5(V+) and 7,8(V-). For the “R” model, the voltage is reversed. 4,5(V-) and 7,8(V+). The Ethernet spec supports distances up to 100m (328 feet).

There are models available that support 802.3af and 802.3at, as well as models that support Gigabit Ethernet. The units are autoranging so that they accept AC inputs from 90VAC to 264VAC (50/60 Hz) and they supply a regulated DC Voltage at the output. They have various protections for surge, short circuit, overload, and overvoltage. The medium power model has a power output of up to 24W. They provide 48-56V DC Output with load regulation within 5%. The CI model has a special current sense LED that changes color when a PoE device is plugged into the CAT5 cable.

If the remote device does not support power over Ethernet, splitters (POE-SPLT-S) are available to split the data and DC voltage at the remote device. If the remote device requires reverse voltage, the POE-XOVER cable can be used.
