The QLT A40LVB50000N is a constant voltage 24V to constant current 500mA converter manufactured by QLT, designed specifically to drive COB LED modules. Built in PVC, the device features an exceptionally compact footprint — 50 x 48 x 11 mm — making it easy to integrate into luminaires and recessed lighting systems. The output voltage ranging from 37 to 40V ensures precise and stable power delivery to connected LED modules.
Thanks to PWM dimmability, this converter allows smooth and accurate control of light intensity, making it particularly well suited to installations where precise lighting adjustment is required in both residential and professional settings. The IP20 protection rating makes it suitable for built-in indoor installations only, while insulation class II ensures a high level of electrical safety. The device features protection against open circuit and short circuits, and is supplied complete with M/F mini amp connectors. Compatibility with the main international voltage standards — EU, AUS, USA, UK and Japan — makes it suitable for a wide range of applications worldwide.
