The TP-POE-48GD Gigabit 802.3af 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 provide the 802.3af function to prevent powering the POE port if a valid 802.3af client is not detected. 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. They are autoranging so that they accept AC inputs from 90VAC to 264VAC (50/60 Hz) and they supply regulated 24VDC at the output. And also have various protections for surge, short circuit and overload. Output is 48VDC with load regulation within 5%.
