The TP-POE-24G Gigabit Power Over Ethernet Power Source/Inserter offered by Tycon Power Systems are quality power sources for years of reliable operation even in the toughest conditions. They accept data-in to a shielded RJ45 Jack and provide 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-). The Ethernet spec supports distances up to 100m (328 feet). The POE inserters have built in Ethernet surge protection which eliminates the need for a standalone Ethernet surge protector. The TP-POE-24G are autoranging so that they accept AC inputs from 90VAC to 264VAC (50/60 Hz) and they supply regulated 24VDC at the output. They have various protections for surge, short circuit and overload. Output is 24VDC with load regulation within 5%.
