Abstract

An uninterruptible power supply (“UPS”) includes an input module having a plurality of inputs, and at least one jumper element configured to selectively couple at least one input of the plurality of inputs to at least one other input of the plurality of inputs. The plurality of inputs and the at least one jumper element may be constructed and arranged to selectively achieve the following configurations: single power feed, single phase input and single phase output; dual power feed, single phase input and single phase output; single power feed, three phase input and single phase output; dual power feed, three phase input and single phase output; single power feed, three phase input and three phase output; and dual power feed, three phase input and three phase output. Other embodiments and methods of selectively achieving multiple power configurations are also disclosed.

Claims

1. A configurable power module for an Uninterruptible Power Supply (UPS), the power module comprising:

a housing having an exterior region and an interior region;

a plurality of input terminals located in the interior region of the housing, each input terminal being configured to be coupled to a wire;

a plurality of output terminals located on the exterior region of the housing, each output terminal being electrically coupled to at least one of the plurality of input terminals and configured to be coupled to a receptacle of the UPS; and

at least one jumper element adapted to connect at least two of the plurality of input terminals in parallel,

wherein the plurality of input and output terminals are configured to provide a wiring scheme; and

wherein the wiring scheme is selectively configured based on the configuration of the at least one jumper element.

2. The power module of claim 1, wherein the wiring scheme is configured as one of a single feed wiring scheme or multi-feed wiring scheme depending on the configuration of the at least one jumper element.

3. The power module of claim 1, wherein the wiring scheme is configured as one of a single phase wiring scheme or multi-phase wiring scheme depending on the configuration of the at least one jumper element.

4. The power module of claim 1, wherein the wiring scheme is configured as one of a single phase input, single phase output, multi-phase input, or multi-phase output wiring scheme.

5. The power module of claim 1, wherein the power module is an input power module, and wherein the plurality of input terminals are coupled to at least one external AC source and are configured to receive at least one input AC signal from the external AC source and transfer at least one output AC signal to the UPS via the plurality of output terminals.

6. The power module of claim 5, wherein a first segment of the plurality of input terminals are configured to be coupled to a main AC source and a second segment of the plurality of input terminals are configured to be coupled to an auxiliary AC source.

7. The power module of claim 1, wherein the power module is an output power module, wherein the plurality of input terminals are coupled to at least one external device, and wherein the plurality of output terminals are configured to receive an input AC signal from the UPS and transfer an output AC signal to the at least one external device via the plurality of input terminals.

8. The power module of claim 1, wherein at least one jumper element comprises at least one blocking segment configured to prevent physical access to at least one of the plurality of input terminals.

9. The power module of claim 1, wherein the plurality of output terminals includes a neutral output terminal and the plurality of input terminals includes a neutral input terminal, and wherein the neutral input terminal is coupled to a neutral wire.

10. The power module of claim 1, wherein the plurality of output terminals includes a ground output terminal and the plurality of input terminals includes a ground input terminal, and wherein the ground input terminal is coupled to a ground wire.

11. The power module of claim 1, wherein each of the plurality of input terminals comprises a screw lug, and wherein the screw lug is configured to be coupled to the wire.

12. The power module of claim 1, further comprising at least one cutout configured to provide access from the external region to the internal region and to receive the wire.

13. A method for providing a configurable power module for an Uninterruptible Power Supply (UPS), the method comprising:

providing a housing having an exterior region and an interior region;

providing a plurality of input terminals located in the interior region of the housing, each input terminal being configured to be coupled to a wire;

providing a plurality of output terminals located on the exterior region of the housing, each output terminal being electrically coupled to at least one of the plurality of input terminals and configured to be coupled to a receptacle of the UPS;

connecting at least two of the plurality of input terminals in parallel with at least one jumper element; and

selectively configuring the plurality of input and output terminals to provide a wiring scheme based on the configuration of the at least one jumper element.

14. The method of claim 13, wherein selectively configuring the plurality of input and output terminals includes configuring the plurality of input and output terminals to provide one of a single feed wiring scheme or multi-feed wiring scheme depending on the configuration of the at least one jumper element.

15. The method of claim 13, wherein selectively configuring the plurality of input and output terminals includes configuring the plurality of input and output terminals to provide one of a single phase wiring scheme or a multi-phase wiring scheme depending on the configuration of the at least one jumper element.

16. The method of claim 13, wherein selectively configuring the plurality of input and output terminals includes configuring the plurality of input and output terminals to provide one of a single phase input, single phase output, multi-phase input, or multi-phase output wiring scheme.

17. The method of claim 13, further comprising:

receiving, with at least one of the plurality of input terminals, at least one input AC signal from an external AC source; and

transferring at least one output AC signal to the UPS via the plurality of output terminals.

18. The method of claim 17, wherein receiving at least one input AC signal includes receiving a main AC signal and an auxiliary AC signal, and wherein transferring at least one output AC signal includes transferring a main output AC signal and an auxiliary output AC signal.

19. The method of claim 13, further comprising:

receiving, with at least one of the plurality of output terminals, at least one input AC signal from the UPS; and

transferring at least one output AC signal to at least one external device via the plurality of input terminals.

20. The method of claim 13, further comprising preventing physical access to at least one of the plurality of input terminals.
