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

Can I use the ELG-75-C500DA to drive LED downlights in a commercial building with DALI lighting controls?

Yes. The ELG-75-C500DA supports DALI dimming, making it compatible with DALI-based building automation and lighting control systems. It delivers 500mA constant current at up to 75W, which suits mid-power LED downlight arrays where DALI dimming is required.

Is the ELG-75-C500DA suitable for outdoor LED signage installations?

Yes. The ELG-75-C500DA carries an IP67 waterproof rating, meaning it can withstand temporary immersion and is suitable for outdoor LED signage and exterior lighting enclosures. Its working case temperature (Tcase) range of -40°C to +85°C covers most outdoor climates.

Can the ELG-75-C500DA power a series string of LED modules in a linear lighting fixture?

Yes. It operates as a constant current driver at 500mA, with a CC voltage range of 75–150V dc. LED modules connected in series whose combined forward voltage falls within that range can be driven by this unit at up to 75W total.

What LED arrays are compatible with the ELG-75-C500DA's output?

Any LED array or series string that requires 500mA constant current and has a total forward voltage within the 75–150V CC range is compatible. The number of LEDs that fit depends on each LED's individual forward voltage.

Can the ELG-75-C500DA be installed in an unenclosed outdoor location?

It is rated IP67, which provides protection against dust ingress and temporary water immersion, so it can tolerate wet outdoor conditions. However, local electrical codes may still require a suitable enclosure; always verify installation requirements for the specific environment.

How does the ELG-75-C500DA differ from the ELG-75-C500 and ELG-75-C500A in the same family?

The ELG-75-C500 has no dimming capability. The ELG-75-C500A adds output current adjustment via a built-in potentiometer (250–500mA). The ELG-75-C500DA instead offers DALI digital dimming control. All three share the same 75W, 500mA constant current output.
