OSRAM QTI DALI 4X14/24 DIM quicktronic intelligent T5 1-10V Electronic Ballast

OSRAM QTI DALI 4X14/24 DIM is an intelligent electronic ballast from the Quicktronic range by OSRAM, designed for the control and dimmable regulation of T5 fluorescent neon discharge lamps. Built in steel with a white finish, its compact body measures 360 × 40 × 21 mm with an IP20 protection rating. It supports up to 4 light sources at 4×14/24W, an input voltage of 220–240 V (operating range 198–264 V AC and 154–276 V DC) and an operating frequency between 44 and 120 kHz. Dimming is managed via the DALI interface and 1-10V system, in full compliance with IEC 60929 and IEC 62386 standards.

This electronic ballast is particularly suited for professional installations in industrial environments, corridors, open-plan offices, sports halls, retail spaces and emergency lighting systems conforming to EN 50172/DIN VDE 0108-100. The Touch DIM function enables straightforward dimming without additional controllers, using standard switches, while the memory function (double click) and soft start ensure reliable, uninterrupted operation. Overvoltage and polarity reversal protection, together with automatic restart after lamp replacement, complete a high-performance technical profile that guarantees stable output and extended lamp lifespan.
