The 4-Key Matter + Zigbee Rotary & Push Button Smart Dimmer can operate with either a two-wire connection without a neutral lead or a three-wire connection with a neutral lead. It is equipped with advanced microprocessor control, smart light source detection, and active power and energy metering functionality. The dimmer features a soft start function, along with innovative minimum dimming level and startup brightness setting functions. It supports a wide range of dimmable light sources, including conventional incandescent and HV halogen light sources, ELV halogen lamps, dimmable LED bulbs (with electronic transformers), MLV halogen lamps (with ferromagnetic transformers), and dimmable CFL tube lamps. Additionally, the Bypass extension unit supports dimmable light sources with a power factor greater than 0.5 and a minimum power of 3VA. The dimmer is compatible with both trailing edge for resistive and capacitive loads, as well as leading edge for inductive loads.
