Universal dimming actuator IP via Wi-Fi. Matter-certified, REST-API. With power MOSFET. Dimmable 230V LED lamps in phase cut-off mode up to 300W or in phase control mode up to 100W depending on ventilation conditions. 230V incandescent lamps and halogen lamps up to 300W depending on ventilation conditions. No minimum load. Only 0.7 watt standby loss. For installation. 49x51mm wide, 25mm deep. The terminals are plug-in terminals for conductor cross-sections of 0.2mm2 to 2.5mm2. Zero passage switching with soft ON and soft OFF to protect lamps. Supply voltage, switching voltage and control voltage local 110-240V. The brightness level is stored on switch-off (memory). If supply voltage fails, the device is ­switched off in defined mode. Automatic electronic overload protection and overtemperature switch-off. With control input for a mains voltage control button that may be installed in front of it. Glow lamp current is not permitted. The Wi-Fi link uses the 2.4 GHz frequency band and permits Over-the-Air updates (OTA). This actuator is Matter certified and can therefore be taught-in into different ecosystems and operated in parallel. To control via Matter, a compatible Matter controller is required for each ecosystem. For Apple Home, for example, a Homepod mini, for Amazon Alexa, for example, a compatible Echo Dot and for Google Home, for example, a Nest mini. As an option, the actuator can be configured via the ELTAKO Connect app. A development version of the REST API is available through the device‘s online product page. This is continuously being further developed.
