TP-POE-48GD, The 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 802.3af PoE 
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-48GD are autoranging so that they accept AC inputs from 90VAC to 
264VAC (50/60 Hz) and they supply regulated 48VDC at the output. They have 
various protections for surge, short circuit and overload. 
Output is 48VDC with load regulation within 5%.
