Abstract
An electrical power distribution system has fixed stations with AC power to DC power conversion circuitry at these stations. The converter(s) are switchable ON/OFF at outlet ports or sockets where the socket configuration permits. Standardized DC sockets accommodate a variety of voltage requirements typical of portable digital devices. In some embodiments feedback circuitry is provided to regulate the power to these devices in accordance with parameters programmed in the portable devices or in the sensing circuitry provided at each station.
Claims7
An electrical power distribution system for a building wherein AC power cables are provided to a plurality of stations in the building, the system comprising:
- an AC to DC converter for providing low voltage DC power at selected stations in the building;
- DC outlet sockets electrically coupled to said AC to DC converter by a voltage regulator, wherein some of said DC outlets sockets include at least one of the group comprising USB ports and FIREWIRE ports;
- and
- a switch coupled between said AC to DC converter and said some DC outlet sockets for selectively energizing some of said DC outlet sockets;
- wherein said switch comprises a moveable support for said DC outlet socket, whereby inserting a charging device plug into said DC outlet socket energizes said AC to DC converter and provides DC voltage to a device to be powered;
- whereby various DC voltages are available at said plurality of DC outlet sockets for powering devices having various voltage requirements.
