BOKE BK-DGL040S-A1050ADN 40W DALI-2 DT8 Tunable White Constant Current LED Driver

150–1050mA DALI-2 DT8 Driver with Push DIM/CCT, NFC Programming and Advanced Lighting Functions

The BOKE BK-DGL040S-A1050ADN is a 40W constant-current tunable white LED driver designed for professional linear, office and commercial lighting applications. It provides an adjustable output current from 150mA to 1050mA, a 12–54V DC output range and a maximum output power of 40W, allowing the driver to be configured for a wide range of two-channel warm white and cool white LED modules.

Supporting DALI-2 DT8, Push DIM and Push CCT control, the driver provides coordinated brightness and colour temperature adjustment through its two output channels. DALI DT8 allows both channels to operate from a single DALI address, simplifying commissioning of tunable white luminaires. Push-button control can also be used for stepless brightness and colour temperature adjustment, with memory retaining the previous brightness and CCT settings after power cycling.

The BK-DGL040S-A1050ADN provides smooth 1–100% dimming with flicker-free performance and BOKE HPC technology designed to maintain consistent luminaire brightness throughout the dimming range. Output current can be programmed in 1mA steps within the supported operating window, allowing precise matching to the connected LED module while keeping total output power within the driver's 40W rating.

Advanced EasySet programming can be carried out through either the DALI interface or NFC using compatible BOKE programming tools. Configurable functions include adjustable output current, DALI addressing and parameters, Push DIM/CCT, corridorDIM, emergency lighting, constant light output, hot-plug protection and power-on behaviour. DALI Parts 251, 252 and 253 are also supported for luminaire data, energy reporting and diagnostic or maintenance information.

Additional functionality includes CLO constant-light-output compensation, corridorDIM for motion-sensor-controlled lighting, central and self-contained emergency lighting support and intelligent LED hot-plug protection. These features make the driver particularly suitable for office luminaires, linear lighting, tri-proof fittings, workplace lighting and other professional lighting installations where flexible control and long-term maintainability are required.

Operating from 200–240V AC or DC, the driver provides approximately 90% typical efficiency with a power factor of approximately 0.97. Short-circuit, overload, no-load and hot-plug protection are provided, while the IP20 SELV design is intended for indoor luminaire installation. A nominal service life of up to 100,000 hours and a 5.5-year manufacturer guarantee provide additional reassurance for commercial and specification-grade lighting projects.
