OSRAM QTI DALI 4x18 DIM quicktronic intelligent DALI Electronic Ballast

OSRAM QTI DALI 4x18 DIM is an intelligent electronic ballast manufactured by Osram, designed to control and dim four 18 W neon discharge lamps. Built in white steel with a compact footprint — 360 mm in length, 40 mm in width and 21 mm in depth — it integrates seamlessly into existing luminaires. Its DALI interface, compliant with IEC 60929 and IEC 62386 standards, enables precise and flexible lighting management with continuous dimming and no flickering, including on amalgam lamps.

This electronic ballast is ideally suited to professional installations requiring advanced lighting control: industry, open-plan offices, corridors, sports halls, retail environments and emergency lighting systems in accordance with EN 50172/DIN VDE 0108-100. The Touch DIM function allows manual dimming using standard switches without a dedicated controller, while the memory function and soft start ensure reliable, long-lasting operation. With an IP20 protection rating and an input voltage of 220–240 V (198–264 V AC), it is fully compatible with standard European electrical installations. Automatic restart after lamp replacement and built-in protection against overvoltage and polarity reversal complete an outstanding technical profile.
