The lumDATA DALI-2 compatible LED driver is a dimmable built-in constant current solution, designed for linear and area lighting in office environments. It supports full dimming from 1 to 100 percent and allows output current adjustment between 900 and 1,750 mA through ready2mains Programmer, I-SELECT 2 plugs, or DALI interfaces. With a maximum output power of 60 W and efficiency reaching up to 90 percent, the driver maintains extremely low standby power consumption below 0.2 W. Its nominal lifetime extends up to 100,000 hours, backed by a five-year manufacturer guarantee.
The driver’s casing is constructed from durable white polycarbonate, offering protection class IP20. It incorporates multiple interfaces, including one4all for DALI-2 DT 6, DSI, switchDIM, and corridorFUNCTION, as well as ready2mains for configuration and dimming via mains voltage. Terminal blocks support 45° push connections, enabling straightforward installation and secure wiring.
Functionality is extensive, with the driver allowing precise output current adjustment in 1-mA steps through DALI, ready2mains, or I-SELECT 2. It complies with DALI-2 parts 251 (luminaire data), 252 (energy reporting), and 253 (diagnostics and maintenance), and features a constant light output (CLO) function to maintain consistent brightness. Additional features include power-up fading at AC, fade2zero switch-off, configurable ready2mains settings, and a service monitor for event logging. The driver also integrates protective mechanisms against overtemperature, short-circuit, overload, no-load, and input voltage deviations, along with reduced surge amplification. Its reliability extends to emergency escape lighting systems, conforming to EN 50172.
The lumDATA driver offers a broad, application-oriented operating window that ensures compatibility across a variety of office luminaire configurations. Its combination of low standby power and high efficiency minimizes energy losses, while flexible configuration via DALI, ready2mains, and I-SELECT 2 allows easy adaptation to different installation requirements.
Electrical specifications include a rated supply voltage of 220 to 240 V with AC operating range of 198 to 264 V and DC range of 176 to 280 V, compatible with mains frequencies of 0, 50, or 60 Hz. The driver withstands overvoltage up to 320 V AC for 48 hours, while typical current consumption ranges from 241 to 293 mA at full load, dropping to 43 to 54 mA at 15 percent dimming level. Leakage current remains below 0.7 mA, and no-load input current is 22 mA. Peak inrush current reaches 26 A with a duration of 264 µs, and maximum input power is 70 W. Efficiency at full load is 90 percent, power factor reaches 0.98, and total harmonic distortion remains below 7 percent. The driver starts in under 0.7 seconds on AC and 0.4 seconds on DC, with a switchover time between AC and DC of under 0.4 seconds and turn-off time below 0.03 seconds. Output current tolerance is ±3 percent, with maximum non-repetitive peak currents up to 40 percent above nominal. Output low-frequency ripple stays within ±3 percent, and output P_ST_LM and SVM remain within ≤1 and ≤0.4, respectively. Maximum output voltage is 60 V, with dimming range fully covering 1 to 100 percent. Surge capability includes 1 kV between L-N, 2 kV between L/N-PE, and output-side surge voltage against PE under 0.5 kV. Physical dimensions are 125 mm in length, 85 mm in width, and 28.3 mm in height, supporting a lifetime of up to 100,000 hours.
This driver delivers a highly reliable, configurable, and efficient solution for modern office lighting, combining DALI-2 compatibility, precise dimming, long lifetime, and robust protection for demanding linear and area lighting applications.
