QLT driver PBX-D 24V dimmable 0-10V 1-10V DALI2

The QLT driver PBX-D 24V dimmable is a professional LED power supply manufactured by QLT, designed for technical lighting installations that demand precise and flexible dimming control. Built in polycarbonate with a compact footprint of 206 x 75 x 35 mm, it delivers a constant 24V PWM voltage output and natively supports the DALI2, 1-10V, 0-10V and PUSH dimming protocols, selectable via dip-switches. The IP20 protection rating makes it suitable for indoor use, while insulation class II ensures protection against both direct and indirect electrical contact.

This dimmable driver is ideal for architectural and technical lighting systems where centralised light management and installation scalability are essential. Available in four power versions — 75W, 100W, 150W and 200W — it suits installations of varying scale, with a universal input of 100-240V AC and a stabilised 24V output. Key features include the ability to synchronise multiple drivers, a double output connector with quick-release terminals, and self-resetting protection against overtemperature, open circuit and short-circuit conditions on the secondary. On request, a 230V DC power supply version and a boosted 110V version are also available.
