Abstract
Abstract An electrical system for controlling the supply of power to several items of electrical equipment via a power bus, an interface bus and respective connector assemblies. Each connector assembly has a connector containing a power switch connected to a monitor and an interface unit, which controls operation of the switch. The interface unit also receives configuration data about the power requirements of the respective item of equipment from a configurations code device in a mating connector on the equipment. The interface unit supplies signals to a control unit via the interface bus and receives signals from the control unit to control switching of the power switch.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
125 words
An electrical system comprising: a power supply system, a plurality of items of electrical equipment and a plurality of connector assemblies, wherein each item of electrical equipment has configuration data encoded therein, wherein the power supply system includes a control unit and a power bus, wherein the connector assemblies connect each respective item of equipment to the power bus, and wherein each connector assembly includes a power switch for controlling supply of power to the respective equipment, means for reading the said configuration data of the respective equipment and signalling means interconnecting the control unit with both the power switch and the configuration data reading means so that control unit can identify the configuration of each item of equipment and control its power switch accordingly.
Claim 2
Dependent Claim
125 words
An electrical system comprising: a power supply system, a plurality of items of electrical equipment and a plurality of connector assemblies, wherein each item of electrical equipment has configuration data encoded therein, wherein the power supply system includes a control unit and a power bus, wherein the connector assemblies connect each respective item of equipment to the power bus, and wherein each connector assembly includes a power switch for controlling supply of power to the respective equipment, means for reading the said configuration data of the respective equipment and signalling means interconnecting the control unit with both the power switch and the configuration data reading means so that control unit can identify the configuration of each item of equipment and control its power switch accordingly.
Claim 3
Dependent Claim
22 words
An electrical system according to claim 1, wherein the signalling means includes an electrically-conductive interface bus, which connects to the control unit.
Claim 4
Dependent Claim
21 words
An electrical system according to claim 1, wherein the configuration data is indicative of the power requirement of the respective equipment.
Claim 5
Dependent Claim
23 words
An electrical system according to claim 1, wherein the configuration data is provided by a configurations code device formed by a hard-wired connection.
Claim 6
Dependent Claim
49 words
An electrical system according to claim 1, wherein each connector assembly includes a monitor arranged to monitor operation of the respective equipment, and wherein said signalling means is interconnected with said monitor so that the power switch can be controlled by the control unit in response to the monitor.
Claim 7
Dependent Claim
18 words
An electrical system according to claim 5, wherein the monitor monitors the power drawn by the respective equipment.
Claim 8
Dependent Claim
20 words
An electrical system according to claim 5, wherein the monitor monitors the temperature in the region of the power switch.
