QLT Constant Multi-Current LED Driver Dimmable 1-10V With Low Voltage Button

The QLT A40PDMC1000B dimmable multi-current LED driver is a constant current power supply designed by QLT for powering and dimming LED light sources. Built in PVC, the device features a compact form factor — 138 × 40 × 18.5 mm — making it straightforward to install even in confined spaces. Its primary function is to deliver a stable, adjustable power supply to LED strips and modules, while protecting the circuit against overheating, short-circuits and open-circuit faults through a self-restoring protection system.

One of the most distinctive features of this driver is the ability to select the output current across thirteen distinct values — from 100 mA up to 700 mA — via DIP-switch micro switches, supporting a maximum power of 13 W at 230 V and 9 W at 110 V. Dimming is achieved via the 1-10V system combined with a simple NA (Normally Open) push button, enabling immediate and intuitive control of light intensity without the need for additional complex equipment. The universal input range of 100–240 V AC ensures compatibility with the main international electrical standards — EU, USA, UK, AUS, JAP — while the IP20 protection rating and Class II insulation classification make it suitable for indoor installations.
