QLT 24V LED Constant Voltage Driver Dimmable DALI / PUSH With Low Voltage Button

The QLT A40PDCVD000B is a 24V DC constant voltage dimmable LED driver, designed by QLT to power and regulate the brightness of LED strips and lighting systems. Built in PVC with a compact profile — 138 mm in length, 40 mm in width and 18.5 mm in depth — it stands out for its dual integrated control capability: it supports both DALI dimming and Push-Button control via a simple NA (Normally Open) button on the primary side, combining two dimming modes within a single compact device.

This driver is designed for technical installations requiring precise and flexible light control. Its universal input voltage range of 100–240V AC ensures compatibility with the main international electrical standards (EU, USA, UK, Australia, Japan), making it suitable for both residential and professional environments worldwide. The maximum output power is 13W at 230V and 10W at 110V, with a stabilised 24V DC output. The IP20 protection rating makes it suitable for indoor installations, while the Class II insulation ensures electrical safety without the need for earthing. Integrated self-resetting protections against overtemperatures, output short circuits and open circuit conditions guarantee long-term reliability and uninterrupted performance.
