The Mean Well SPWM DA2Q series is a range of 24V constant voltage DALI-2 LED drivers, designed for LED strip lighting in commercial, architectural, and decorative applications.

Using PWM-style output, the drivers maintain consistent brightness and colour performance, making them ideal for high-quality lighting installations where stability and precision are essential.

The DA2Q version supports DALI-2 DT8 dimming, enabling advanced control of tunable white (CCT) and multi-channel colour lighting (RGB/RGBW) within a single driver. This allows smooth adjustment between warm and cool white, as well as dynamic colour control for compatible LED systems.

Designed for integration into modern lighting control systems, DT8 enables centralised control of both brightness and colour, making it ideal for smart building, commercial, and architectural lighting applications.

Designed for long-term operation, the SPWM series combines high efficiency (up to 93–94%) with a fanless cooling design, ensuring silent operation and reduced maintenance.

With a wide 180–305VAC input range, low standby power consumption, and a service life exceeding 50,000 hours, these drivers deliver dependable performance across a wide range of installations.

The slim, compact housing makes them suitable for space-constrained installations, while built-in protection features ensure safe and reliable operation.
