DALI, AstroDIM, StepDIM, MainsDIM – constant current LED drivers. Product features: Available with different wattage: 40 W, 60 W, 90 W, 165 W. Input voltage: 120…277 V (40 W), 220…240 V (60 W, 90 W, 165 W). Current output range: 70…1,050 mA. Flexible current setting with one additional wire (LEDset2). AstroDIM for autonomous dimming with five independent levels (astro, time mode). Allows for energy saving in twilight phases. MainsDIM function for dimming via reduction of line voltage amplitude. Isolated DALI interface for bidirectional telemanagement systems. Standby power consumption: < 0.5 W. Constant lumen function. Overtemperature protection via external NTC. Product benefits: 4DIM functionality in one device (StepDIM, AstroDIM, MainsDIM, DALI). Very high efficiency and reliability. High surge protection: up to 10 kV (1 pulse) / 8 kV, in protection class I or II. Low luminous efficacy tolerance through low output current tolerance of ± 3 %. Great flexibility due to wide operating temperature range of -40…55 °C or 60 °C. Protection through double isolation between mains input and LED output. Areas of application: Street and urban lighting. Industry. Suitable for outdoor applications in luminaires with IP > 54. Suitable for use in outdoor luminaires of protection class I and II. Equipment / Accessories: DALI magic hardware for configuring 4DIM ECGs necessary. Programmable via Tuner4TRONIC™ software.
