Universal dimmer switch. Power MOSFET up to 400 W. Automatic lamp detection. Standby loss only 0.1 watts. Minimum brightness or dimming speed adjustable. Includes children's room and snooze function. For flush mounting. 45 mm long, 45 mm wide, 18 mm deep. Universal dimmer switch for lamps up to 400 W, depending on ventilation conditions. Dimmable energy-saving lamps (ESL) and dimmable 230 V LED lamps also depend on the lamp electronics. Switching at zero crossing with soft on and soft off to protect the lamp. Control voltage, supply voltage, and switching voltage 230 V. No minimum load required. Short control commands turn on/off, continuous control changes the brightness up to the maximum value. Interrupting the control changes the dimming direction. The set brightness level is saved when switched off (memory). In the event of a power failure, the switching position and brightness level are stored and can be restored when the voltage returns.
