Abstract

A power distribution unit (“PDU”) comprises a housing, a power module mechanically connected to the housing, at least one outlet module separately and mechanically connected to the housing, and a communications module mechanically connected to the housing. The PDU includes busbars that are electrically connected to the modules.

Claims

1. A power distribution unit (“

PDU,”

) comprising;

an input power component;

a first outlet component including a first plurality of outlets permanently fixed to a first chassis and a plurality of first busbars extending the length of the first outlet component,

wherein the first plurality of outlets includes multiple first groups of outlets,

wherein each first group of outlets includes a first printed circuit board assembly (“

PCBA”

) having at least one microprocessor, and

wherein the first busbars are electrically connected to the input power component;

a communications component in signal communication with the first outlet component for transferring data; and

a housing connected to the input power component, the first outlet component, and the communications component.

2. The PDU of claim 1, further comprising a second outlet component,

wherein the second outlet component includes a second plurality of outlets permanently fixed to a second chassis, and a plurality of second busbars extending the length of the second outlet component.

3. The PDU of claim 1, wherein each first group of outlets includes a relay board containing a plurality of relays, each relay capable of electrically connecting or disconnecting an outlet to a busbar.

4. The PDU of claim 1, wherein each of the first groups of outlets are electrically connected to the first busbars via a plurality of jumpers.

5. The PDU of claim 4, wherein each outlet includes an electrically conductive outlet pin that is electrically connected to one of the plurality of jumpers, and wherein the jumper is also electrically connected to a busbar.

6. The PDU of claim 4, wherein the plurality of jumpers includes first jumpers having a first length and second jumpers having a second length greater than the first length.

7. A power distribution unit (“

PDU”

) assembly comprising;

a plurality of outlets;

at least one pin extending from each outlet;

a plurality of busbars;

a plurality of jumpers extending between the busbars and the outlet pins,

wherein each jumper electrically connects a single outlet pin to a single busbar; and

a flat insulator sheet located between the outlets and the electrical connections,

wherein the flat insulator sheet includes a plurality of slots sized and shaped to receive the outlet pins.

8. The PDU assembly of claim 7, further including a chassis having a plurality of openings, each opening sized and shaped to receive a group of outlets.

9. The PDU assembly of claim 7, wherein each outlet is electrically connected to two busbars.

10. The PDU assembly of claim 7, wherein each of the plurality of jumpers includes a non-conductive housing and a conductive element.

11. The PDU assembly of claim 7, wherein the PDU assembly shares a chassis with an input power component.

12. The PDU of claim 7, wherein the plurality of jumpers includes first jumpers having a first length and second jumpers having a second length greater than the first length.

13. A power distribution unit assembly comprising:

a housing;

a power source mechanically connected to the housing;

a plurality of outlets mechanically connected to the housing,

wherein the plurality of outlets includes multiple groups of outlets, and

wherein each group of outlets includes a printed circuit board assembly having at least one microprocessor;

a set of busbars; and

a plurality of jumpers that electrically connect at least some of the plurality of outlets to the set of busbars, wherein the plurality of jumpers includes first jumpers having a first length and second jumpers having a second length greater than the first length.

14. The power distribution unit assembly of claim 13, wherein the set of busbars includes a first set of busbars and a second set of busbars, and wherein the first set of busbars are electrically connected to the second set of busbars via one or more wires.

15. The power distribution unit assembly of claim 13, wherein the set of busbars includes a first set of busbars and a second set of busbars, and wherein the first set of busbars and second set of busbars are not electrically connected to each other.

16. The power distribution unit assembly of claim 13, further including a communications module mechanically connected to the housing.

17. The power distribution unit assembly of claim 16, wherein there are no direct mechanical connections between the power source, the plurality of outlets, or the communications module.

18. The power distribution unit assembly of claim 13, wherein at least one of the set of busbars carries an input current, wherein at least one of the set of busbars is a neutral line, and wherein each of the plurality of outlets is connected to the input current by a first jumper and to the neutral line by a second jumper.

19. The power distribution unit assembly of claim 13, wherein at least one of the set of busbars carries current from a first electrical phase, wherein at least one of the set of busbars carries current from a second electrical phase, and wherein each of the plurality of outlets is connected to a first phase by a first jumper and to a second phase by a second jumper.
