Abstract

Methods, systems, and apparatuses provide power from multiple input power sources to adjacent outputs efficiently and reliably. Aspects of the disclosure provide a power distribution unit (PDU) that includes a number of power outputs including first and second adjacent power outputs. The PDU includes a printed circuit board having a first conducting layer electrically interconnected to a first power input connection and the first power output, a second conducting layer that is at least partially above the first conducting layer and in facing relationship thereto. The second conducting layer is electrically insulated from the first conducting layer and electrically interconnected with a second power input connection and the second power output, the first and second power outputs thereby connected to different power inputs.

First claim

We claim:

1. A power distribution apparatus comprising:
a power distribution unit housing;
at least one power input disposed at least partially within the housing comprising at least a first input line and a second input line; and
at least one outlet comprising at least a primary connector and a secondary connector;
at least one printed circuit board disposed in the housing comprising at least two conducting layers, at least one of the two conducting layers comprising at least a first conducting region and a second conducting region, wherein
the first conducting region is electrically interconnected to the first input line and the primary connector, and
the second conducting region is electrically insulated from the first conducting region and electrically interconnected to the second input line and the secondary connector.

2. The apparatus of claim 1 , further comprising:
a plurality of power control relays disposed in the housing, each power control relay being connected in independent power controlling communication between the at least one power input and the at least one outlet.

3. The apparatus of claim 1 , further comprising:
a current-related information reporting system disposed at least partially in the housing in current-related information determining communication with the at least one outlet, the at least one power input, or a combination thereof, and connectable in current-related information transfer communication with a separate communications network distal from the power distribution apparatus.

4. The apparatus of claim 1 , wherein the at least one power input comprises multiple power phase inputs connectable to different respective power sources.

5. The apparatus of claim 1 , wherein the at least one power input comprises a three phase power input.

6. A power distribution apparatus comprising:
a power distribution unit housing;
at least one power input disposed at least partially within the housing comprising a plurality of input lines, wherein the at least one power input is electrically connectable to at least two different power sources;
a plurality of outlets comprising at least a first outlet and a second outlet located adjacent to the first outlet;
at least one printed circuit board disposed in the housing comprising:
(i) a first conducting layer electrically interconnected with at least a first input line of the plurality of input lines and electrically interconnected with the first outlet,
(ii) a second conducting layer located at least partially above the first conducting layer and in facing relationship thereto, electrically insulated from the first conducting layer, electrically interconnected with at least a second input line of the plurality of input lines, and electrically interconnected with the second outlet,
wherein at least one of the first conducting layer and the second conducting layer includes at least a first conducting region and a second conducting region, the first conducting region being electrically insulated from the second conducting region, and the first and second conducting regions being electrically interconnected with different input lines of the plurality of input lines.

7. The apparatus of claim 6 , further comprising:
a plurality of power control relays disposed in the housing, each power control relay being connected in independent power controlling communication between the at least one power input and at least one of the plurality of outlets.

8. The apparatus of claim 6 , further comprising:
a current-related information reporting system disposed in the housing in current-related information determining communication with one or more of the plurality of outlets, the power input, or a combination thereof, and connectable in current-related information transfer communication with a separate communications network distal from the power distribution apparatus.

9. The apparatus of claim 6 , wherein the at least one power input comprises a three phase power input.

10. The apparatus of claim 6 , wherein the printed circuit board further comprises a first conductively plated through hole extending through the first and second conducting layers, electrically connected to the first conducting layer, electrically insulated from the second conducting layer, and electrically interconnected to the first outlet.

11. The apparatus of claim 10 , wherein the printed circuit board further comprises a second conductively plated through hole extending through the first and second conducting layers, electrically connected to the second conducting layer, electrically insulated from the first conducting layer, and electrically interconnected to the second outlet.

12. The apparatus of claim 6 ,
wherein the plurality of outlets further comprises a third outlet located adjacent to the second outlet, and
wherein the printed circuit board further comprises:
(iii) a third conducting layer located at least partially above the first and second conducting layers, electrically insulated from the first and second conducting layers, electrically interconnected with at least a third input line of the plurality of input lines, and electrically interconnected with the third outlet.

13. The apparatus of claim 12 , wherein the printed circuit board further comprises:
a first conductively plated through hole extending through the first, second, and third conducting layers, electrically connected to the first conducting layer, electrically insulated from the second and third conducting layers, and electrically interconnected to the first outlet;
a second conductively plated through hole extending through the first, second, and third conducting layers, electrically connected to the second conducting layer, electrically insulated from the first and third conducting layers, and electrically interconnected to the second outlet;
