Abstract
A device and method are provided for detecting and configuring a solid state dimmer when wired in series or parallel with a load powered by an alternating current (AC) input. The device can comprise a microcontroller configured to be powered by the AC input. A zero-cross detector in communication with the microcontroller is capable of detecting when an AC waveform crosses zero and generating a corresponding pulse signal when the AC waveform crosses zero. A pulse analyzer can be included and configured to determine when the zero-cross detector is generating pulses exceeding a pre-determined time length threshold that represents a serial wiring configuration.
