The in-wall dimmer actuator allows for dimming and switching on or off of many dimmable LEDs, dimmable energy-saving lamps, low-voltage halogen lamps, high-voltage halogen lamps, and incandescent bulbs. Note: This is a kit that needs to be assembled. The dimmer is particularly suitable for dimming smaller loads, such as those typically represented by LED lighting. The phase-cut dimmer, designed with modern circuit technology, operates silently compared to older dimmers. It enables dimming and switching on or off of many dimmable LEDs, dimmable energy-saving lamps, low-voltage halogen lamps with electronic transformers, high-voltage halogen lamps, and incandescent bulbs up to 80 VA. Optimized for modern light sources, making it especially suitable for small loads (e.g., LED) starting from 3 VA. Connected lights can be dimmed in 0.5% steps almost continuously via the Homematic IP app. Low standby power consumption. Compact design for easy installation in flush-mounted boxes or surface-mounted junction boxes for use in basements or outdoor areas. Tool-free terminals for particularly easy installation. Convenient control via the Homematic IP app or Homematic IP remote control. Comfortable configuration and linking through the Homematic IP app or Smart Home centers. Voice control with Amazon Alexa and Google Assistant is possible. ARR kit with housing. Operation requires connection to one of the following solutions: Homematic IP Access Point with free smartphone app and free cloud service, CCU2/CCU3 central unit with local user interface, WebUI, radio modules for Raspberry Pi, third-party partner solutions.
