34 in stock


Product family benefits
– Versatile DALI window driver due to flexible output characteristic
– Very high efficiency
– Protection of the system thanks to thermal management and Smart Control
– High-quality dimming of 1…100 % by amplitude dimming
– Versatile scope of application due to OSRAM DALI Technology:
– Easy to use in corridors and restrooms because of the three-level Corridor function
– Touch DIM application: easy to control via pushbutton or sensor
– Energy efficient Touch DIM operation due to automatic switch-off at sufficient residual light
