## CPC

- H02M 7/003: {Constructional details, e.g. physical layout, assembly, wiring or busbar connections}
- H02M: APPARATUS FOR CONVERSION BETWEEN AC AND AC, BETWEEN AC AND DC, OR BETWEEN DC AND DC, AND FOR USE WITH MAINS OR SIMILAR POWER SUPPLY SYSTEMS; CONVERSION OF DC OR AC INPUT POWER INTO SURGE OUTPUT POWER; CONTROL OR REGULATION THEREOF (transformers H01F; dynamo-electric converters H02K47/00; controlling transformers, reactors or choke coils, control or regulation of electric motors, generators or dynamo-electric converters H02P)

## Abstract

A modular power supply (1) includes a primary input portion (2) operating with predetermined input parameters, and an output portion (3) comprising at least two modules (4) to be selected for modifying the power supply's output parameters. It is further provided a container (5) in which the primary input portion and the output portion are housed. The container comprises an inaccessible portion (6) adapted to house the primary input portion separated from the output portion, and a cover (7) hinged on a base structure (8) of the container for access to the output portion. The inaccessible portion of the container comprises a partition (9) disposed between the primary input portion and the output portion and provided with openings (10) for cooling the primary input and secondary portions. The openings are such disposed that access to the primary input portion is not allowed.

## Claims

### Claim 1

A modular power supply (1) comprising:
a primary input portion (2) operating with predetermined input parameters, and
an output portion (3) comprising at least two modules (4) to be selected for modifying the power supply's output parameters,
a container (5) in which the primary input portion (2) and the output portion (3) are housed, wherein said container (5) comprises:
an inaccessible portion (6) adapted to house the primary input portion (2) separated from the output portion (3), and
a cover (7) hinged on a base structure (8) of the container (5) for access to the output portion (3).

### Claim 2 (depends on 1)

A modular power supply (1) as claimed in claim 1, wherein the inaccessible portion (6) of the container (5) comprises a partition (9) disposed between the primary input portion (2) and the output portion (3) for separating the two portions.

### Claim 3 (depends on 2)

A modular power supply (1) as claimed in claim 2, wherein the partition (9) comprises openings (10) for cooling the primary input portion and the output portion (2, 3), said cooling openings (10) being disposed in such a manner as to enable access to the primary input portion (2).

### Claim 4 (depends on 2)

A modular power supply (1) as claimed in claim 2, wherein the cover (7) comprises an extension (11) suitable to bear on the inaccessible portion (6) of the container (5).

### Claim 5 (depends on 2)

A modular power supply (1) as claimed in claim 2, wherein said inaccessible portion (6) of the container (5) comprises a wrapping structure (12) and an inner structure (13) inside said wrapping structure (12), wherein said inner structure (13) comprises the partition (9) and houses the primary input portion (2).

### Claim 6 (depends on 5)

A modular power supply (1) as claimed in claim 5, wherein the inner structure (13) is made of a plastic material and the wrapping structure (12), the base structure (8) and cover (7) of the container (5) are made of a metallic material.

### Claim 7 (depends on 1)

A modular power supply (1) as claimed in claim 1, wherein the cover (7) is hinged on the base structure (8) of the container (5) at a portion external or internal to the container's overall dimensions.

### Claim 8 (depends on 1)

A modular power supply (1) as claimed in claim 1, wherein the cover is hinged to the base structure at two opposite portions disposed to one end of the base structure.

### Claim 9 (depends on 1)

A modular power supply (1) as claimed in claim 1, wherein the cover (7) and the base structure (8) have extensions (14, 15) in which a pin (16) defining the hinged connection is housed.

### Claim 10 (depends on 1)

A modular power supply (1) as claimed in claim 1, wherein said inaccessible portion (6) of the container (5) comprises an upper wall (12c) fixed to side walls (12b) to prevent user's access to the primary input portion (2).

### Claim 11 (depends on 5)

A modular power supply (1) as claimed in claim 5 wherein the wrapping structure (12) surrounds the inner structure (13) only partly.
