For switching and dimming incandescent lamps, HV halogen lamps, LV halogen lamps via dimmable wound transformers or electronic transformers, LEDs and compact fluorescent lamps (leading and trailing edge phase control). The universal dimmer automatically detects the connected load. With the included diode modules, e.g. 2-button operation can be implemented (button 1 dim on/up, button 2 dim off/down) or up to 3 lighting scenes can be called up. In addition, a dimming time can be set for different functions. Combinations of inductive and capacitive loads must not be connected. For mounting on TH35 top hat rails in accordance with EN 60715. Functions Automatic load detection. Switch-on brightness can be stored individually. Adjustable minimum brightness (required for ESL and LEDs). Multi-voltage input, e.g. for intercom systems. Memory function in the event of a power failure. Automatic electronic overload and overtemperature shutdown. Dimming switch-on function. Permanent ON function (test function). Soft ON and soft OFF protect the light source. No minimum load required. Comfort setting with wake-up and snooze function (can also be deactivated). Adjustable dimming speed (for automatic functions). One and two-button operation for the simplest operation. Up to 3 light scenes can be called up via a separate input. Central OFF/ON for max. 10 dimming channels or light scene for max. 10 devices possible with one button. Staircase light function with dimming function in accordance with DIN 18015 - 2 (can be switched on later, long-term function). Can be controlled via button or switch, e.g. for combination with presence detectors or timer. Nominal voltage AC 230 V, +10% / -15%, 50 Hz. Own consumption 0.3 W. Standby power 0.2 W.
