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 80℃ 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
Can the ELG-100-C1050DA be integrated into a DALI lighting control system for smart building use?
Yes. The 'DA' suffix indicates a DALI interface, allowing the driver to be controlled and addressed within a DALI digital lighting control network. The DALI protocol comprises 16 groups and 64 addresses, enabling per-fixture or group dimming from a DALI controller.
Is the ELG-100-C1050DA rated for outdoor use in wet environments?
Yes. The ELG-100-C1050DA carries an IP67 waterproof rating, making it suitable for outdoor luminaires and applications where the driver may be exposed to rain, splashing, or temporary water contact.
Can I use the ELG-100-C1050DA to power LED downlights in an office building with centralized dimming?
Yes. The DALI interface of this driver supports central dimming control from a building management system, making it practical for office environments that require zoned or scene-based lighting. It operates at 99.75W and 1050mA constant current.
What LED string forward voltage range is compatible with the ELG-100-C1050DA?
For the DA-Type, the CC output voltage range is 57–95V (60–100% of maximum voltage). LED series strings with a combined forward voltage within this window are compatible; the number of LEDs per series string depends on each LED's individual forward voltage specification.
Is the ELG-100-C1050DA suitable for LED signage in a retail environment that requires centralized brightness control?
Yes. DALI-based dimming allows a retail lighting controller to adjust the sign brightness by zone or schedule, and the constant current output ensures consistent LED brightness across the sign panel. The driver handles 99.75W across a 57–95V CC range.
