The TP-POE-24G-WP GigE Power Over Ethernet Power Sources are a low cost
Passive PoE inserter/injector compatible with a wide variety of passive PoE
powered devices. They are midspan devices, which means there is a data-in port
and an output port with data and power. The RJ45 connectors are shielded so that
the CAT5 cable shielding path is not interrupted between the data source
(computer, router or switch) and the device being supplied with PoE power. The
small size and convenient wall plug design helps keep the installation simple
and clean. The low cost makes them very affordable.
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 units are autoranging so that they accept AC inputs from 90VAC to 264VAC
(50/60 Hz) and they supply regulated DC Voltage at the PoE output. They have
various protections for short circuit, overload and overvoltage. They have power
output of up to 24W. They are 24VDC Output with load regulation within 5%. They
have an LED to indicate power on.
