Abstract

Power supply system for mounting to a rail has an AC/DC converter for converting high voltage AC power to low voltage DC power a controller for controlling the power supply system, an AC/DC converter and controller module for mounting to the rail and for connection to the AC/DC converter and controller respectively, and a battery connection and LVBD contactor module for mounting to the rail and for connection to a first battery, wherein the battery connection and LVBD contactor module on a first side is connected to the AC/DC converter and controller module by a first connection interface and where the battery connection and LVBD contactor module on a second side, opposite of the first side, has a first connector of a second connection interface.

Claims

1. Power supply system for mounting to a rail comprising an AC/DC converter for converting high voltage AC power to low voltage DC power;

a controller for controlling the power supply system;

wherein the system comprises;

an AC/DC converter and controller module for mounting to the rail and for connection to the AC/DC converter and controller respectively;

a battery connection and LVBD contactor module for mounting to the rail and for connection to a first battery, wherein the battery connection and LVBD contactor module on a first side is connected to the AC/DC converter and controller module by a first connection interface and wherein the battery connection and LVBD contactor module on a second side, opposite of the first side, comprises a first connector of a second connection interface; and

a first load connection module for mounting to the rail and for connection to a first load, wherein the first load connection module on a first side comprises a second connector of the second connection interface and on a second side, opposite of the first side, comprises a third connector of the second connection interface, wherein the second connector of the first load connection module is connected to first connector on the second side of the battery connection and LVBD contactor module;

wherein the LVBD contactor of the battery connection and LVBD contactor module is provided for controlled connection or disconnection of the first battery, and

wherein the first and second connection interfaces comprise DC power terminals for transferring DC power and signal terminals for transferring control signals.

2. The power supply system according to claim 1, wherein the first load connection module is a load connection and LD contactor module comprising an LD contactor provided for controlled connection or disconnection of the load being connected to the load connection and LD contactor module and, if present, subsequent load connection modules connected to the third connector on the second side of the load connection and LD contactor module.

3. The power supply system according to claim 1, wherein one or more load connection modules or load connection and LD contactor modules are connected subsequent to the first load connection module for connection of more load to the power supply system.

4. The power supply system according to claim 1, wherein a battery connection module is mounted to the rail and is connected between the battery connection and LVBD contactor module and the first load connection module for connection of more batteries to the power supply system.

5. The power supply system according to claim 4, wherein the battery connection module on a first side comprises a fourth connector for connection to the first connector of the battery connection and LVBD contactor module and on a second side, opposite of the first side, comprises a fifth connector equal to the first connector for connection to the second connector of the first load connection module.

6. The power supply system according to claim 1, wherein the second connector of one module may be connected to the first connector, the fifth connector or the third connector of another module.

7. The power supply system according to claim 1, wherein the fourth connector of a module may be connected to the first connector or a fifth connector of another module, but may not be connected to the third connector of another module.

8. The power supply system according to claim 1, wherein the DC power terminals of the first, third and fifth connectors are female connectors and the DC power terminals of the second and fourth connectors are male connectors or vice versa.

9. The power supply system according to claim 1, wherein the first, fourth and fifth connectors comprise three DC power terminals, a positive terminal, a negative load terminal and a negative battery terminal.

10. The power supply system according to claim 9, wherein the second and third connectors comprise two DC power terminals:

the positive terminal, and the negative load terminal.

11. The power supply system according to claim 1, wherein the load is connected to the load connection module by one or several MCBs.

12. The power supply system according to claim 1, wherein the battery is connected to the battery connection and LVBD contactor module or, if present, the battery connection module, by one or several MCBs.
