Abstract

Claims (53)

1. A load control system, comprising:

a power supply;

a load controller coupled to a load, the load controller receives a first power having a first current level from the power supply, and uses the first power to cause a plurality of resistors to output a plurality of pre-defined codes; and

a supply controller that receives the plurality of pre-defined codes, evaluates an output condition based on the plurality of pre-defined codes, and causes the power supply to output a second power having a second current level greater than the first level responsive to the plurality of pre-defined codes satisfying the output condition.

2. The load control system of claim 1 , comprising:

the supply controller activates a first switch to couple the power supply to a circuit path coupled to the load controller and the load.

3. The load control system of claim 1 , comprising:

a second switch that the load controller activates to couple the load to the power supply.

4. The load control system of claim 1 , comprising:

the supply controller includes a memory maintaining a plurality of supply codes and evaluates the output condition based on matching the plurality of pre-defined codes to the plurality of supply codes.

5. The load control system of claim 1 , comprising:

at least one sensor detects a current and a voltage of a signal representative of each pre-defined code, and the supply controller extracts the pre-defined code based on the current and voltage.

the supply controller at least one of filters and decrypts a signal received from the plurality of resistors representative of a corresponding pre-defined code.

7. The load control system of claim 1 , comprising:

the load controller receives the first power from the power supply via a first circuit path and provides the plurality of pre-defined codes to the supply controller via a second circuit path.

8. The load control system of claim 1 , comprising:

the supply controller outputs an alert responsive to the plurality of pre-defined codes not satisfying the output condition.

receiving, at the supply controller, the plurality of pre-defined codes;

evaluating, by the supply controller, an output condition based on the plurality of pre-defined codes; and

connecting, by the supply controller, the load to the power supply responsive to the plurality of pre-defined codes satisfying the output condition.

11. The method of claim 10 , comprising:

increasing the current limit to a second value greater than the first value responsive to the plurality of pre-defined codes satisfying the output condition.

12. The method of claim 10 , comprising:

activating, by the supply controller, a first switch to couple the power supply to a circuit path coupled to the load controller and the load.

maintaining, in memory of the supply controller, a plurality of supply codes; and

evaluating, by the supply controller, the output condition based on matching the plurality of pre-defined codes to the plurality of supply codes.

14. The method of claim 10 , comprising:

detecting, by at least one sensor, a current and a voltage of a signal representative of each pre-defined code; and

extracting, by the supply controller, the pre-defined code based on the current and voltage.
