Abstract

A universal load control module may include a power supply that operates over a wide voltage range, a microcontroller, and one or more functional control blocks. A functional control block may include a dimmer circuit for controlling a lighting load that provides reverse phase cut mode dimming, forward phase cut mode dimming, and hybrid phase cut mode dimming, as well as thermal protection. One or more universal control modules may be housed in a cabinet that include a cabinet control module. The cabinet may include additional thermal protection measures.

First claim

What is claimed is:

a plurality of load control modules, wherein each load control module is connected to an output of at least one of the branch circuit breakers and each load control module includes a power supply capable of operating over the wide voltage range, and wherein each of the load control modules controls at least one lighting load;
a cabinet control module, wherein the cabinet control module configures the load control modules and provides an external communication interface;
a first set of conductors for connecting the load control modules with the outputs of the branch circuit breakers; and
a second set of conductors for connecting the load control modules with the cabinet control module.

2. The cabinet of claim 1 , wherein at least one of the load control modules includes a first functional control block that provides lighting control and a second functional control block that provides a communication or control interface.

3. The cabinet of claim 1 , wherein at least one of the load control modules includes a first functional control block that includes a dimmer circuit and a first power supply block that provides isolation between a high voltage and a low voltage, a microcontroller, and a zero cross detection circuit.

4. The cabinet of claim 1 , further comprising a control module that provides a control or communication interface, wherein the control module includes a power supply that operates over the wide voltage range by detecting an input voltage and adjusting its operation based on the input voltage to provide at least one output voltage to components of the load control module.

5. The cabinet of claim 1 , wherein the cabinet includes an access panel to provide access to the branch circuit breakers and the cabinet control module.

6. The cabinet of claim 1 , further comprising a display device, wherein the cabinet control module interfaces with the display device.

7. The cabinet of claim 1 , further comprising an input device, wherein the cabinet control module interfaces with the input device.

8. A cabinet, comprising:
a plurality of branch circuit breakers, wherein each branch circuit breaker is capable of operating over a wide voltage range;
a plurality of load control modules, wherein each load control module is connected to an output of at least one of the branch circuit breakers and each load control module includes a power supply capable of operating over the wide voltage range and wherein each of the load control modules controls at least one lighting load;
a cabinet control module, wherein the cabinet control module configures the load control modules and provides an external communication interface;
a first set of conductors for connecting the control modules with the outputs of the branch circuit breakers; and
a second set of conductors for connecting the control modules with the cabinet control module.

9. The cabinet of claim 8 , further comprising a plurality of terminal blocks, wherein one of the terminal blocks connects one of the load control modules to one of the conductors of the first set of conductors.

10. The cabinet of claim 8 , wherein the cabinet includes an access panel that allows access to the branch circuit breakers and the cabinet control module.

11. The cabinet of claim 8 , further comprising a distribution block, wherein the distribution block is connected to a main circuit breaker that is external to the cabinet and to the branch circuit breakers.

12. The cabinet of claim 8 , wherein at least one of the load control modules includes a first functional control block that includes a dimmer circuit and a first power supply block that provides isolation between a high voltage and a low voltage, a microcontroller, and a zero cross detection circuit.

13. The cabinet of claim 8 , further comprising a display device, wherein the cabinet control module interfaces with the display device.

14. The cabinet of claim 8 , further comprising an input device, wherein the cabinet control module interfaces with the input device.

15. A cabinet, comprising:
a plurality of load control modules, wherein each load control module includes a power supply capable of automatically detecting an input voltage and adjusting operations to operate over a wide voltage range and wherein each of the load control modules controls at least one lighting load;
a cabinet control module, wherein the cabinet control module configures the load control modules and provides an external communication interface;
a first set of conductors for providing power to the control modules; and
a second set of conductors for connecting the control modules with the cabinet control module.

16. The cabinet of claim 15 , wherein the first set of conductors are connected to a plurality of branch circuit breakers located external to the cabinet.

17. The cabinet of claim 15 , further comprising a plurality of branch circuit breakers, wherein each branch circuit breaker is capable of operating over the wide voltage range and each load control module is connected to an output of at least one of the branch circuit breakers.
