Description

The TP-POE-1824 is a unique Power Over Ethernet adapter which converts an 802.3af/at 48VDC POE input into a 18V or 24VDC regulated passive POE output. The POE output voltage is external jumper selectable and capable of up to 25W power output. The POE input is IEEE 802.3af/at compatible so the TP-POE-1824 will work with standard 802.3af/at compliant POE switches or routers. The TP-POE-1824 enables the powering of passive POE devices from standard 802.3af/at POE switches, which eliminates the extra expenses usually required to power non compliant equipment.

There are two models available:
TP-POE-1824 which is 10/100MB compatible and has a 12W output.
TP-POE-1824G which is 10/100/1000MB compatible and has a 24W output.

They accept data-in and 802.3af/at POE to a shielded RJ45 Jack and provide data-out and 18V or 24V POE on the shielded RJ45 output jack. They workby 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).
They have various protections for surge, short circuit, overload and overvoltage.
