NETWORK POWER SPLITTER FOR SUPPLYING POWER FROM A NETWORK TO A PORTABLE ELECTRONIC DEVICE

摘要

A network power splitter includes a circuit coupled to a local area network (LAN) for receiving power from the LAN. The circuit includes a limited current circuit for limiting the amount of current transmitted from the LAN to a portable electronic device and a detect and switch circuit for detecting compliance with the IEEE 802.3af power standard and activating or deactivating the network power splitter accordingly. The network power splitter also contains a power converter coupled to said circuit for transforming the power received from the circuit such that the transformed power conforms to electrical characteristics of the portable electronic device, the power converter comprising a voltage transformer for transforming a voltage of the power received from the circuit into a voltage usable by the portable electronic device, and one or more power output interfaces for outputting said converted power to one or more portable electronic devices.
