QLT Driver 11W 25V 500mA dimmable TRIAC

The QLT Driver 11W 25V 500mA dimmable TRIAC, reference A40PLKE2050B, is a constant-current LED driver manufactured by QLT, designed to deliver stable and adjustable power to LED light sources. Built in PVC, its compact dimensions — 118 mm in length, 33 mm in width and 19 mm in depth — make installation straightforward even in confined spaces.

This driver supplies a constant output current of 500mA at a maximum power output of 11W, ensuring consistent and reliable performance over time. The TRIAC phase-cut dimming function, compatible with TRIAC, IGBT and MOSFET dimmers for both resistive and inductive loads, allows smooth adjustment of light intensity directly on the primary side — making it particularly suitable for professional installations where precise light control is essential. The input voltage of 220–240V AC is compatible with the main international standards (EU, AUS, USA, UK, JAP). The IP20 protection rating and Insulation Class II ensure safe use in indoor environments, while self-resetting protection against overtemperatures, short circuits and open-circuit conditions on the secondary side completes the technical profile of this driver.
