摘要： In a load control system as described, each of a plurality of switch circuits includes a switch electrically connected between an associated one second terminal out of a plurality of second terminals and a first terminal. A control circuit controls the switch that each of the plurality of switch circuits includes and thereby controls supply of power to a load associated with each of the plurality of switch circuits. A power supply circuit is electrically connected between the plurality of second terminals and the first terminal and receives power from a power supply via the first terminal and at least one second terminal out of the plurality of second terminals and thereby generates power to be supplied to at least the control circuit.

摘要： A multiple location dimming system may include a smart dimmer (e.g., a main load control device) and one or more remote dimmers (e.g., accessory devices) for controlling the amount of power delivered to a lighting load. The multiple location dimming system may be installed in place of a multiple location switch system (e.g., having three, four, or more multi-way switches), and may not require a neutral connection at any of the control devices of the multiple location dimming system. The main load control device and the accessory devices of the multiple location dimming system may be configured to display a present intensity level of a lighting load on one or more visual indicators. The accessory devices may have the same or different user interfaces as the main load control device, and may provide additional functionality over that which the main load control device offers.

摘要： Disclosed is a phase-cut dimmer, comprising an AC switch coupled in series between an AC supply and a load; a DC power supply powered from a voltage across the switch; a zero-crossing detector of a phase-cut AC voltage across the switch; a timer generating a timing signal of a duty-cycle proportional to a variable fraction of a peak voltage of a sawtooth signal, wherein the sawtooth signal is synchronized to the zero-crossing detector; a blanking signal generator triggered by a duty-cycle detector to reduce the duty-cycle when the duty-cycle of the timing signal exceeds a predetermined maximum limit; and an operation mode selector activated by an output of an inductive load detector.
