LTECH SE-40-300-1050-W1D 40W DALI-2 Constant Current LED Driver

300–1050mA DALI-2 DT6 Driver with NFC Programming

The LTECH SE-40-300-1050-W1D is a compact 40W constant-current LED driver designed for professional indoor lighting applications. With an adjustable output current from 300mA to 1050mA and an output voltage range of up to 9–42V DC, it provides flexible compatibility with a wide range of constant-current LED modules.

Supporting DALI-2 DT6 control, the driver provides smooth digital dimming from 0–100% down to 0.01%. LTECH T-PWM™ dimming technology delivers flicker-free performance, while soft-on and fade-in functions help provide comfortable and precise low-level lighting control.

Integrated NFC programming allows the output current to be adjusted in 1mA steps, while the DALI address, dimming curve and other operating parameters can also be configured using a compatible smartphone and the LTECH NFC Lighting app. DALI groups and scenes can be programmed through the advanced DALI template, helping simplify commissioning and system setup.

Operating from a universal 100–240V AC input, the SE-40-300-1050-W1D offers up to 88% efficiency and includes overheat, over-voltage, overload and short-circuit protection with automatic recovery. Its compact Class II construction, 100,000-hour nominal service life and 5-year manufacturer warranty make it a dependable solution for professional constant-current LED lighting systems.
