摘要： Two-wire dimmer operation includes applying first and second control pulses to a switching circuit controlled between ON and OFF states, the first control pulse beginning at a first starting time and extending for a first duration of time that ends at a first ending time, and the second control pulse beginning at a second starting time, after the first ending time, and extending for a second duration of time that ends at a second ending time, detecting levels of current provided to a lighting load during the first duration of time and during the second duration of time, comparing current levels determined based on applying the first and second control pulses, based on the comparing, ascertaining a load type of the lighting load, and selecting, based on the ascertained load type, parameters that control dimming operation of the dimmer.

摘要： Circuit interrupting devices are provided. One circuit interrupting device includes a fault sensor configured to output a sensor signal; a voltage sensor configured to sense a reference voltage; and a controller configured to determine an occurrence of an actual fault based on the sensor signal and the reference voltage. The circuit interrupting device further includes an amplifier configured to receive the sensor signal and the reference voltage and output an amplified signal; an analog-to-digital converter configured to receive the reference voltage and the amplified signal and output respective digital signals corresponding to the reference voltage and the amplified signal; and a line interrupt assembly configured to interrupt current flow through a conductive path when a characteristic of the sensor signal exceeds an actual fault threshold.

摘要： Two-wire dimmer operation includes controlling conduction of power to a lighting load. In one aspect, based on a conduction angle adjustment, power supply voltage is monitored and a maximum conduction angle is established based thereon. In another aspect, a dimming level signal is received and a dimming level for a dimmer is set based on the received dimming level. The dimming level signal indicates a desired dimming level for a dimmer, and a maximum value for the dimming level signal is based on a dimmer power supply voltage. In yet another aspect, based on detecting an adjustment to increase a conduction angle of a dimmer, the conduction end angle is increased and the conduction start angle is also increased. This results in a net increase in the conduction angle for controlling operation of the dimmer.

摘要： A process for self testing a fault circuit includes disabling an actuator, performing a self-test by creating a simulated fault signal across at least a portion of a half cycle of a first polarity and across at least a portion of a half cycle of a second polarity, and determining whether the self-test was successful.
