Owner's manual

Ltech MT-1A-V2D1 is a DALI constant voltage driver, designed for use with magnetic and linear lamps. It features no input polarity, DC to DC constant current output, and DALI 2.0 protocol. Its ultra-small size makes it suitable for STUCCHI standard housings, and its magnetic installation is quiet, without high-frequency sound. The MT-1A-V2D1 offers smooth dimming curves without kicker, and protects against short circuit, overload, and anti-reverse conditions. It supports hot plugging and has no input polarity, allowing for normal output regardless of input polarity.
