Abstract: A load control system comprises a load control device and a battery-powered occupancy sensor, which transmits a first wireless signal to the load control device in response to detecting the presence of an occupant in a space. The load control system further comprises a visual indicator for providing a visual indication when the magnitude of a battery voltage of a battery of the occupancy sensor has dropped below a predetermined low-battery voltage threshold. The occupancy sensor may comprise the visual indicator, such that the visual indicator is illuminated when the occupancy detects the presence of the occupant in the space and the magnitude of the battery voltage is less than the predetermined threshold. Alternatively, the load control device may comprise the visual indicator, such that the visual indicator is illuminated in response to receiving a second wireless signal, which is transmitting by the occupancy sensor when the magnitude of the battery voltage is less than the predetermined threshold.

Abstract: A two-wire load control device may be configured to compute an accurate estimate of real-time power consumption by a load that is electrically connected to, and controlled by, the two-wire load control device. The load control device may be adapted to measure a voltage drop across the device during a first portion of a half-cycle of an AC waveform provided to the device. The device may be further configured to estimate a voltage drop across the load during the second portion of the half-cycle. The estimated voltage drop may be based on the measured voltage drop. The device may be further configured to measure a current supplied to the load during a second portion of the half-cycle. The device may be configured to estimate power consumed by the load based on the measured current and the estimated voltage drop.

Abstract: A load control device for controlling the amount of power delivered to an electrical load may include a rectifier circuit configured to receive a phase-control voltage and produce a rectified voltage. A power converter may be configured to receive the rectified voltage at an input and generate a bus voltage. An input capacitor may be coupled across the input of the power converter. The input capacitor may be adapted to charge when the magnitude of the phase control voltage is approximately zero volts. The power converter may be configured to operate in a boost mode, such that the magnitude of the bus voltage is greater than a peak magnitude of the input voltage. The power converter may be configured to operate in a buck mode to charge the input capacitor from the bus voltage when the magnitude of the phase-control voltage is approximately zero volts.
