LTECH MT-300-450-D2D1 18.9W DALI-2 DT8 Tunable White LED Driver

300–450mA Constant Current Driver for 48V Magnetic Track and Linear Lighting

The LTECH MT-300-450-D2D1 is an ultra-compact constant-current LED driver designed for 48V magnetic track and linear tunable white lighting systems. Supporting DALI-2 DT8 control with two output channels, it provides coordinated brightness and colour temperature control for retail, hospitality, commercial and architectural lighting applications.

Operating from a polarity-free 48V DC input, the driver provides an adjustable constant-current output from 300mA to 450mA with an output voltage range of 9–42V DC. Four selectable current settings of 300mA, 350mA, 400mA and 450mA can be configured using the onboard DIP switch, allowing the driver to be matched easily to compatible LED modules.

The MT-300-450-D2D1 provides smooth DALI dimming from 0–100% down to 0.1% and delivers up to 18.9W of output power. Its DALI-2 DT8 interface enables brightness and colour temperature control through a compatible DALI system, while its slim PCB format is designed for integration into STUCCHI standard magnetic track housings.

Compact and easy to integrate, the driver offers typical efficiency of at least 87% together with overload, short-circuit, no-load and reverse-polarity protection. Quiet operation without high-frequency noise, smooth dimming performance and a 5-year manufacturer warranty make it a practical solution for professional tunable white magnetic track and linear lighting systems.
