SL Power Electronics' Power over Ethernet (PoE) is an evolving technology that supplies reliable DC power over the same cables that currently carry Ethernet data. The PoE is modeled after the technology used by the telecommunications industry to supply reliable power to telephones. This enables lifeline quality power for voice over internet protocol telephones as well as many other low power Ethernet devices.
The PoE power supply can be located anywhere within 100 meters of the application versus a separate power source that would need to be located within six feet. With PoE, the power supply can be located in a wiring closet or anywhere that is away from the applications. Power and data are united with only one wire versus two wiring solutions. Because PoE eliminates the need for running both data and power wires to each network device, installation costs are lower.
