OSRAM QTi DALI 2x14/24 DIM - Dimmable DALI electronic ballast for 2 T5 lamps (14 W / 24 W) with Touch DIM
The OSRAM QTi DALI 2x14/24 DIM is a professional electronic ballast from the QUICKTRONIC Intelligent family, designed to power and regulate two 16mm T5 fluorescent lamps with wattages of 14W or 24W . It features a DALI interface and Touch DIM/Touch DIM Sensor functions for control without a dedicated controller, as well as a corridor function that allows direct connection to common occupancy sensors. It offers smooth and stable dimming in the 1-100% range, safe start, level memory (double press), and soft start , with high efficiency and standby power consumption of less than 0.5W.
It is suitable for use in open-plan offices, corridors, warehouses, retail stores, public buildings, and industrial settings , and for Class I protection luminaires. It complies with DALI (IEC 62386) and applicable EN/IEC standards for electronic control equipment and is ready for SMART GRID (feedback on power consumption and lamp life) and emergency lighting systems via automatic detection by the unit itself. The compact metal design, measuring 423 x 30 x 21 mm, facilitates integration and replacement in luminaires with DALI GI dimensions.
Important note: This product is a DALI ballast for T5 fluorescent lamps . It is not an LED driver, does not use the DMX protocol, and is not intended for RGB LED strips or modules.
