Universal dimming actuator with IP, Matter via Wi-Fi, optional EnOcean. With power mosfet. Dimmable 230 V LED lamps in 'trailing edge phase control' mode up to 300 W, or in 'leading edge phase control' mode up to 100 W, depending on the ventilation conditions. 230 V incandescent and halogen lamps up to 300 W, depending on the ventilation conditions. No minimum load. REST-API. Stand-by loss only 0.7 W. For recessed mounting. 46 x 45 mm, 20 mm deep. The connection terminals are screw terminals for conductor cross-sections up to 2.5 mm². Switching with soft on and soft off to protect the lamp. Supply, switching and control voltage local 110-240 V. The set brightness level is saved when switching off (memory). Automatic electronic overload protection and overtemperature cut-out. With control input for a control button or switch that may be fitted upstream. A glow lamp current is not permitted. The Wi-Fi connection utilises the 2.4 GHz frequency band and enables over-the-air updates (OTA). This actuator is Matter-certified and can therefore be taught into various ecosystems and operated in parallel. For control via Matter, a compatible Matter controller is required for each ecosystem. For Apple Home e.g. a Homepod mini, for Amazon Alexa e.g. a compatible ECHO Dot and for Google Home e.g. a Nest mini. The optional configuration of the actuator is carried out via the ELTAKO Connect app. A development version of the REST API according to the OpenAPI specification is available via the online product page of the device. This is continuously being developed. The range of functions can be extended using plug-on adapters. The EnOcean adapter (EOA64) provides access to the EnOcean ecosystem. Further information on this can be found on the product page of the respective adapter.
