QLT Constant Multi-Current 44W 300-1050mA LED Driver Dimmable DALI/PUSH

The QLT Constant Multi-Current 44W 300-1050mA LED Driver Dimmable DALI/PUSH (ref. A40CC44WD00B) is a professional-grade constant current LED driver manufactured by QLT for demanding lighting installations. Built in PVC with a compact footprint of 163 × 30 × 21 mm, it is engineered to fit into tight technical spaces without compromising performance. Its primary function is to power LED light sources with a selectable constant current output via DIP-switches, ensuring stable and accurate power delivery.

This DALI/PUSH dimmable LED driver is ideally suited for professional lighting projects that demand precise dimming control and installation flexibility. The output current is adjustable across sixteen steps between 300mA and 1050mA, delivering up to 44W at a maximum output voltage of 59V. It supports both DALI and PUSH dimming, with PUSH control achievable via a simple NO (Normally Open) button. Operating on a 220-240V AC input, the driver meets Insulation Class II requirements with an IP20 protection rating. The regulation memory retains settings even after a power loss, while self-resetting protections against overtemperature, short circuits and open circuit conditions on the secondary ensure long-term reliability.
