Abstract
Apparatus and methods for operating low-voltage lighting systems are described. Wiring hubs can reduce installation wiring complexity. A smart power supply can provide more than 100 watts of power on Class 2 low-voltage wiring to compliant loads and limit power delivery to 100 watts for non-compliant loads.
Claims22
A power supply comprising:
- a power source to output electrical current;
- an output terminal coupled to the power source to provide the electrical current to a device when the device is coupled to the output terminal to receive power from the power source;
- power metering circuitry to sense at least one of the electrical current or first electrical power delivered to the output terminal;
- and
- a controller communicatively coupled to the power metering circuitry and the power source, wherein the controller is configured to:
- determine a first amount that is indicative of the first electrical power delivered from the power source to the output terminal to power at least the device when the device is operating and coupled to the output terminal;
- compare the first amount to a second amount, wherein the second amount is indicative of second electrical power consumed by at least the device when the device is operating and coupled to the output terminal;
- and
- if the first amount differs from the second amount by more than a predetermined threshold amount, limit the first electrical power to a predetermined power level.

A method of operating a power supply, the method comprising:
- outputting electrical current with a power source;
- delivering, to an output terminal coupled to the power source, the electrical current to provide first electrical power to a device coupled to the output terminal;
- sensing, with power metering circuitry, at least one of the electrical current or the first electrical power delivered to the output terminal;
- determining, with a controller communicatively coupled to the power metering circuitry, a first amount that is indicative of the first electrical power delivered to the output terminal to power at least the device;
- comparing the first amount to a second amount, wherein the second amount is indicative of second electrical power consumed by at least the device;
- and
- if the first amount differs from the second amount by more than a predetermined threshold amount, limiting the first electrical power to a predetermined power level.
