Lifud LF-BCD040C-1050-54 DALI-2 & Push Dimmable Constant Current LED Driver (16.2–40W)
The Lifud LF-BCD040C-1050-54 is a premium 40W constant current LED driver designed for professional lighting installations requiring exceptional performance, flexibility and reliability. Featuring DALI-2 and Push dimming, this driver delivers smooth, flicker-free dimming from 1–100%, making it ideal for modern commercial, residential and architectural lighting applications.
With a wide adjustable output current of 300–1050mA and an output voltage range of 2.5–54Vdc, a single driver can support a broad range of LED luminaires, reducing inventory requirements and simplifying product selection. Output current is easily configured using the built-in 4-bit DIP switch, providing 16 selectable current settings without the need for additional programming.
Designed with an ultra-slim 21.8mm profile, the LF-BCD040C-1050-54 is suitable for both built-in and independent installations, making it an excellent choice where installation space is limited.
Supporting advanced lighting control features including Emergency Lighting (EL), CorridorDIM, and Constant Light Output (CLO), the driver is also fully compliant with DALI-2 Parts 251, 252 and 253, with operating parameters configurable via a DALI programmer.
Built for long-term reliability, the driver offers up to 90% efficiency, low THD (≤10%), comprehensive protection against electrical faults, and a 100,000-hour design life, backed by a 5-year warranty.
