Test conditions and notes10

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".
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.

FAQ

Is the ELG-75-C1050DA suitable for outdoor LED luminaires in marine or high-humidity environments?

Yes. The ELG-75-C1050DA carries an IP67 waterproof rating and works at case temperatures (Tcase) from -40°C to +85°C. This makes it suitable for LED fixtures in high-humidity environments such as covered marine docks, outdoor pools, and coastal installations where sealing against moisture ingress is critical.

What dimming protocol does the ELG-75-C1050DA support?

The 'DA' suffix indicates this driver supports DALI dimming (IEC62386-101 and 102; 207 by request), allowing integration with DALI-based lighting control systems for centralized or zone-based dimming across 16 groups and 64 addresses. It is compatible with DALI controllers found in commercial building automation and intelligent lighting management platforms.

Can the ELG-75-C1050DA drive LED modules in outdoor architectural downlighting?

Yes. At 1050mA constant current and 74.55W within a CC voltage range of 35–71V, the ELG-75-C1050DA suits medium-wattage LED modules used in outdoor architectural downlights and bollard fixtures. Its IP67 rating and wide input voltage (100–305VAC) allow deployment across both residential and commercial outdoor lighting projects.

Can the ELG-75-C1050DA be used for LED signage modules in a DALI-controlled sign network?

Yes. The ELG-75-C1050DA's DALI interface supports addressable dimming, and its 1050mA constant-current output within 35–71V suits series-wired LED signage modules. This enables centralized brightness control across multiple sign panels from a single DALI controller.

Is the ELG-75-C1050DA certified for use in European and North American markets?

Yes. The ELG-75-C1050DA meets UL8750 (Type HL) and CSA C22.2 No. 250.13-12 for North America and BS EN/EN 61347-1, 61347-2-13 and EN62384 safety plus EN55015/EN61000 EMC standards for Europe. It also meets AS/NZS 61347 (Australia/New Zealand), GB/T19510 (China), EAC (Russia/Eurasia) and KC, making it suitable for international LED lighting projects.
