QLT Multicurrent LED power supply 250-700mA 42W max 84V 1-10V Push Dimmable

QLT A40PUL042BEB is a multicurrent dimmable LED power supply manufactured by QLT, designed for professional LED lighting applications requiring flexibility and precision in current management. The integrated dip-switch allows selection of a constant output current ranging from 250 mA to 700 mA, adapting the driver to different installation configurations without the need for device replacement. The maximum output power is 42W, with output voltage up to 84V and a universal 100-240V AC input compatible with EU, USA, UK, Australian and Japanese electrical standards.

Designed exclusively for indoor use, this power supply supports dimming via 1-10V protocol and PUSH function, with adjustment memory retained even in the absence of mains power. Output current is regulated to a precision of ±5%, including temperature-related variations. The IP40 protection rating and Class II insulation with SELV standard guarantee safety in indoor environments. Self-restoring protections against overheating, open circuit and short circuits ensure long service life and reliability. The compact dimensions of 103 × 68 × 30 mm allow easy installation even in confined spaces.
