Abstract

A power supply assembly which can drive a number of different devices at different voltages. A rack holds a number of breaker modules, and each breaker module can connect to one or many breakout boxes. The breakout boxes are keyed to the breaker modules, so that the breaker boxes will not be energized with power unless they are the proper voltage and/or configuration to receive that power. The coil of a contactor in the breaker module is powered by a key wire that is connected through specified pins in the breakout box. Therefore, no power is ever provided to the breakout box unless it is of the proper voltage configuration. In addition, feeder power to the power supply assembly is provided over bolted connections, without any wire connections between the power feed and the circuit breaker.

Claims

1. A system, comprising:

a power supply, capable of outputting a plurality of different types of power, and producing an output with power of a first type and a first control signal; and

a controller for said output, which supplies power to said output based on a second control signal being received, where said controller supplies power only upon detecting said second control signal as being derived from said first control signal,

wherein said power supply includes a rack, first, second and third busbars, carrying first, second and third power types within said rack, and a connection for each of a plurality of breaker modules, allowing said breaker modules to receive different types of power from said busbars in said rack.

2. A system as in claim 1, further comprising a breakout box, having a cable connection thereto, said breakout box including at least one electrical outlet thereon, and including a portion which produces said second control signal, said portion being keyed with a voltage for said at least one electrical outlet, and said cable connection on said breakout box being connectable to said output and said first control signal in said power supply.

3. A system as in claim 2, wherein said cable connection includes a single cable carrying said electrical power and said second control signal.

4. A system as in claim 3, wherein said single cable also carries network control signals, and said breakout box includes at least one connector which provides said network control signals.

5. A system as in claim 4, wherein said network control signals include ethernet signals.

6. A system as in claim 2, wherein said keyed connection is a loop back between said first control signal being received on the first line, and said loopback connects said first control signal to the specified second line, where the second line is keyed to the voltage of said breakout box.

7. A system as in claim 1, further comprising a cage, coupled between a location where said breaker modules are to be installed, and said bus bars, said cage having holes therein.

8. A system as in claim 7, wherein each of said breaker modules includes at least two connectors, said connectors being sized to extend through said holes in said cage.

9. A system as in claim 8, wherein said holes include at least first and second grounded holes, adapted for supporting said breaker modules.

10. A system as in claim 9, wherein said breaker modules include an extending ground lug, extending further from the breaker module then a tip of said connectors, such that the extending ground lug makes contact with said holes in said cage prior to said connectors on said breaker module extending through said Cage.

11. A system as in claim 10, further comprising roller portions associated with said rack, supporting said breaker modules to be rolled in and out of the rack.

12. A system as in claim 1, further comprising an ethernet switch in the rack, providing ethernet control to said breaker modules.

13. A system, comprising:

a power supply, capable of outputting a plurality of different types of power, and producing an output with power of a first type and a first control signal; and

a controller of said output, which supplies power to said output based on a second control signal being received, wherein said power supply includes a rack, first, second and third busbars, carrying first, second and third power types within said rack, and a connection of each of a plurality of breaker modules, allowing rack, one of said breaker modules, having at least one circuit breaker which controls the output power, said breaker modules each connected to at least two of said busbars, wherein said breaker module includes all metal-to-metal bolted connections between said connection to the busbar, and a connection to said circuit breakers.

14. A system, comprising:

a power supply, capable of outputting a plurality of different types of power, and producing an output with power of a first type and a first control signal;

a controller for said output, which supplies power to said output based on a second control signal being received, where said controller supplies power only upon detecting said second control signal as being derived from said first control signal;

a connector on said power supply, and wherein said power and said control signal are present on a single connector;

a source of network-based signals, and said network-based signals are also present on said single connector; and

a matching connector for said single connector, wherein said matching connector includes at least one ground connector pin a first distance from a bottom surface of the connector, at least one signal pin, for said first and second signals, which extends a second distance from said bottom surface of said connector, and at least one power pin, which extends a third distance from said bottom surface of said connector, wherein said third distance is less than said second distance which is less than said first distance.
