Test conditions and notes11

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
2. Please refer to "DRIVING METHODS OF LED MODULE". For DA-Type, Constant Current region is 60%~100% of maximum voltage under rated power delivery.
3. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
4. Length of set up time is measured at first cold start. Turning ON/OFF the driver may lead to increase of the set up time.
5. The driver is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
6. This series meets the typical life expectancy of >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 75℃ or less.
7. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com.
8. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
9. For any application note and IP water proof function installation caution, please refer our user manual before using. https://www.meanwell.com/Upload/PDF/LED_EN.pdf
10. To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED power supply can only be used behind a switch without permanently connected to the mains.
11. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

Does the ELG-150-C1750DA support DALI dimming for smart building lighting?

Yes. The DA suffix indicates native DALI interface support, allowing the driver to be addressed and dimmed by DALI bus controllers. This makes it suitable for smart building projects requiring addressable, scene-controllable LED downlights or luminaires.

Can the ELG-150-C1750DA power LED downlights in a commercial office fit-out?

Yes. Operating at 1750mA constant current with a 43–86V CC range, it supports series LED arrays used in commercial downlight modules. The DALI interface enables integration with building management systems for zoned and scene-based dimming.

Is the ELG-150-C1750DA rated for outdoor installation in an exposed fixture?

Yes. With an IP67 waterproof rating, the ELG-150-C1750DA is protected against temporary immersion and can be installed in outdoor luminaires or wall-mount fixtures exposed to rain. Its -40°C to +90°C case temperature (Tcase) rating supports year-round outdoor use.

Can I use this driver for LED sign modules in a bus shelter or transit advertising display?

Yes. The constant current 1750mA output and IP67 enclosure are appropriate for transit advertising or bus shelter illuminated displays. The 100–305VAC input accommodates varying supply voltages across different sites, which simplifies deployment in hard-to-reach installations.

How many LEDs can be connected in series to the ELG-150-C1750DA?

The CC compliance range spans 43–86V. The number of series LEDs depends on each LED's forward voltage at 1750mA—you must divide the compliance window by the specific LED's Vf to determine viable string depth. A fixed LED count cannot be given because Vf varies across LED types and operating conditions.

Can this driver be used to retrofit an existing DALI-controlled downlight system?

Yes. The ELG-150-C1750DA complies with DALI standard IEC62386-101 and 102 (207 by request). If the existing system uses a standard DALI bus and controller, this driver can be added to the bus for addressable current-controlled LED loads within the 43–86V compliance range.
