The TP-POE Power Over Ethernet Power Sources offered by Tycon Power Systems are quality midspan power sources 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 regulated DC Voltage at the output. They have various protections for surge, short circuit, overload and overvoltage. The medium power models (TP-POE) have power output up to 24W and the high power models (TP-POE-HP) up to 50W. They are available in 18V, 24V and 48-56V DC Output with load regulation within 5%. The CI model has a special current sense LED which changes color when a POE device is plugged onto the CAT5 cable.
