OSRAM QTI DALI 1x28/54 DIM quicktronic intelligent DALI Electronic Ballast

OSRAM QTI DALI 1x28/54 DIM is an intelligent electronic ballast manufactured by OSRAM, designed to control and dim neon discharge lamps with a power range of 28 W to 54 W. Constructed in white-painted steel, the unit features a compact footprint of 360 × 30 × 21 mm and an IP20 protection rating, making it suitable for installation in protected indoor environments. The device operates at a nominal voltage of 220-240 V (50-60 Hz), accepts AC input from 198 to 264 V and DC input from 154 to 276 V, with an operating frequency between 44 and 120 kHz.

Thanks to full DALI protocol compatibility (compliant with IEC 60929 and IEC 62386), this ballast enables precise and flexible dimming via the DALI interface, with a Touch DIM function that allows manual dimming without a dedicated controller, using standard switches. The unit includes a memory function (double click), soft start and automatic restart after lamp replacement. It delivers the same luminous flux on both AC and DC supply, ensures flicker-free dimming of amalgam lamps, and is suitable for use in emergency lighting systems compliant with EN 50172/DIN VDE 0108-100, as well as in offices, corridors, sports halls, industrial facilities and shop lighting. The corridor function enables direct connection to a standard motion sensor.
