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".
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-75-C350DA be used to drive LED downlights on a DALI-controlled lighting network?

Yes. The DA-suffix designates DALI (Digital Addressable Lighting Interface) dimming capability, making this driver a direct fit for DALI-based lighting systems. It outputs a constant 350mA current and can be individually addressed and dimmed via a DALI bus, which is commonly deployed in commercial downlight installations.

Is the ELG-75-C350DA appropriate for outdoor LED signage modules?

Yes. The ELG-75-C350DA is rated IP67 waterproof and works at case temperatures (Tcase) from -40°C to +85°C, making it suitable for outdoor signage enclosures. The 100–305VAC input supports both 120V and 230V mains supplies used internationally.

Can this driver power a small LED array in an industrial or cold-environment setting?

Yes. With a lower working case temperature limit of -40°C and IP67 protection, the ELG-75-C350DA is rated for harsh industrial and cold-environment deployments. The IP67 rating protects against dust and water ingress in dusty or wet factory conditions.

How many LEDs can I run in series with the ELG-75-C350DA?

The CC voltage range is 107–214V, so the number of LEDs in the series string depends on each LED's individual forward voltage. Ensure the total string forward voltage stays within 107–214V. Strings falling outside this window will cause the driver to operate outside its regulation range.

What certifications are included with the ELG-75-C350DA?

The ELG-75-C350DA meets UL8750 (Type HL), CSA C22.2 No. 250.13-12, BS EN/EN/AS/NZS 61347-1 and 61347-2-13, BS EN/EN62384, GB/T19510, EAC and KC safety standards, and its DALI interface complies with IEC62386-101 and 102. This covers North American, European, Australian, and Chinese market requirements.

How does DALI dimming on the ELG-75-C350DA compare to the PWM dimming on the ELG-75-C350B?

The ELG-75-C350DA uses a DALI bus for digital, addressable dimming that allows individual driver control on a shared two-wire bus, which is standard in building automation systems. The ELG-75-C350B uses three-in-one dimming (0–10V, 10V PWM signal, or resistance) suitable for simpler zone-level control. Both drive a 350mA constant current output at 74.9W with the same CC voltage range of 107–214V.

Can the ELG-75-C350DA be used inside a sealed luminaire fixture for wet locations?

Yes. The IP67 rating means the driver is protected against dust and temporary immersion, making it suitable for use inside sealed luminaire bodies intended for wet or damp locations. The -40°C to +85°C working case temperature (Tcase) range also covers most extreme-environment luminaire applications.
