QLT Dimmable Interface DALI / 1-10V 12-24V 144-288W Dimmable with low voltage push

QLT Dimmable Interface DALI / 1-10V (ref. A40DALI1103B) is a LED strip brightness controller manufactured by QLT, housed in a compact PVC enclosure measuring 138 × 40 × 28.5 mm. It enables smooth and precise dimming of LED light sources via DALI protocol or 1-10V signal, with the operating mode selectable through a jumper (DALI/PUSH or 1-10V), and features a low-voltage push-button input for direct manual control.

Thanks to its flexibility, this dimmer is an ideal solution for both professional and residential LED lighting installations requiring reliable and accurate light control. Compatible with 12V DC (MAX 144W) and 24V DC (MAX 288W) input voltage, it handles resistive loads up to 12A and delivers a 300Hz PWM output for flicker-free, smooth dimming. Insulation class II and IP20 protection rating ensure safe use in indoor environments. The device is compatible with major international voltage standards (EU, USA, UK, AU, JP). To extend the signal across longer lines, the related accessory PWMR is available.
