LTECH LF-40-300-1050-G2D2 40W DALI-2 Tunable White LED Driver

300–1050mA Constant Current Driver with DALI-2 DT6/DT8, Push DIM/CCT and NFC Programming

The LTECH LF-40-300-1050-G2D2 is a slim 40W constant-current LED driver designed for professional tunable white and dimmable linear lighting applications. With an adjustable output current from 300mA to 1050mA, a 9–54V DC output range and up to 40W total output power, it is well suited to office linear lighting, suspended luminaires, floor lamps, batten lights and other commercial lighting installations.

Supporting DALI-2 DT6/DT8 and Push DIM/CCT control, the driver provides smooth dimming from 0–100% down to 0.01% together with adjustable colour temperature control. The CCT range can be configured from 1000K to 10000K, with a default range of 2700K to 6500K. Its constant-power two-channel design helps maintain consistent brightness while adjusting colour temperature, with up to 40W connected to each channel while total output remains within the driver's 40W rating.

Full-command NFC programming allows the output current to be configured in precise 1mA steps using the LTECH NFC Lighting app. Parameters including DALI addressing, dimming curve, brightness range, colour temperature range, fade times, power-on behaviour, CLO light-decay compensation, EL emergency lighting and corridor lighting settings can also be adjusted. L-Data support with DALI Parts 251, 252 and 253 provides access to luminaire data, energy reporting, diagnostics and maintenance information.

Operating from a 220–240V AC input, the LF-40-300-1050-G2D2 provides up to 88% efficiency and includes overheat, over-voltage, overload and short-circuit protection with automatic recovery. Its slim metal construction is available in stand-alone and built-in versions, with the stand-alone model designed to Zhaga Book 24 and the built-in version to Zhaga Books 13 and 24. Low standby consumption, a service life of up to 100,000 hours and a 5-year manufacturer warranty make it a dependable solution for professional tunable white lighting systems.
