摘要： A load control device for controlling the amount of power delivered from an AC power source to an electrical load is operable to conduct enough current through a thyristor of a connected dimmer switch to exceed rated latching and holding currents of the thyristor. The load control device comprises a controllable-load circuit operable to conduct a controllable-load current through the thyristor of the dimmer switch. The load control device disables the controllable-load circuit when the phase-control voltage received from the dimmer switch is a reverse phase-control waveform. When the phase-control voltage received from the dimmer switch is a forward phase-control waveform, the load control device is operable to decrease the magnitude of the controllable-load current so as to conduct only enough current as is required in order to exceed rated latching and holding currents of the thyristor.

摘要： A two-wire load control device such as a dimmer switch for controlling the amount of power delivered from an AC power source to an electrical load such as a high-efficiency lighting load may be provided. The load control device may include a bidirectional semiconductor switch coupled between the source and the load and a controller operable to control the bidirectional semiconductor switch. The load control device may also include a front accessible trimming actuator to adjust a low end intensity setting of the load control device. The trimming actuator may be coupled to the controller such that the controller may control the bidirectional semiconductor switch appropriately. Additionally, the trimming actuator may include indicia to help a user readily identify the proper low end intensity setting.

摘要： A two-wire smart load control device, such as an electronic switch, for controlling the power delivered from a power source to an electrical load comprises a relay for conducting a load current through the load and an in-line power supply coupled in series with the relay for generating a supply voltage across a capacitor when the relay is conductive. The power supply controls when the capacitor charges asynchronously with respect to the frequency of the source. The capacitor conducts the load current for at least a portion of a line cycle of the source when the relay is conductive. The load control device also comprises a bidirectional semiconductor switch, which is controlled to minimize the inrush current conducted through the relay. The bidirectional semiconductor switch is rendered conductive in response to an over-current condition in the capacitor of the power supply, and the relay is rendered non-conductive in response to an over-temperature condition in the power supply.
