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 the ELG-75-C1400DA be integrated into a DALI-controlled smart lighting system?

Yes. The DA suffix on the ELG-75-C1400DA indicates it includes a DALI (Digital Addressable Lighting Interface) dimming input, making it directly compatible with DALI lighting control systems. It delivers 1400mA constant current across a 27–54V range, suitable for LED downlights and small LED arrays in DALI-networked installations.

Is the ELG-75-C1400DA suitable for outdoor LED signage with a DALI control bus?

Yes. The ELG-75-C1400DA carries an IP67 waterproof rating, providing dust protection and temporary submersion resistance. Combined with its DALI dimming capability, it is a suitable choice for outdoor LED signage projects where a DALI control bus is used for centralized brightness management.

Can I use the ELG-75-C1400DA in a museum or gallery LED lighting project requiring smooth, flicker-free DALI dimming?

The ELG-75-C1400DA supports DALI dimming (IEC62386-101/102, 16 groups and 64 addresses), giving digital control suitable for museum and gallery lighting. Its constant current output of 1400mA across 27–54V keeps LED drive current regulated; the spec sheet does not state flicker performance, so verify it against your project requirements.

How does the ELG-75-C1400DA differ from the ELG-75-C1400B?

Both share the same 75.6W / 1400mA output and IP67 rating. The ELG-75-C1400B uses a 3-in-1 dimming interface (0–10V, 10V PWM, resistance), while the ELG-75-C1400DA uses a DALI interface for addressable digital control. The choice depends on your lighting control infrastructure.

What is the operating temperature range of the ELG-75-C1400DA, and can it operate in cold outdoor conditions?

The ELG-75-C1400DA is rated for a working case temperature (Tcase) of -40°C to +85°C, covering extreme cold-weather outdoor deployments; at high ambient temperatures the load derates per the load vs temperature curve. Its IP67 rating also protects against dust and moisture ingress in those conditions.

Can the ELG-75-C1400DA drive LED modules in a small series-connected array for architectural lighting?

Yes. As a constant current driver outputting 1400mA, the ELG-75-C1400DA maintains stable current through a series LED string regardless of load variation, making it well suited for architectural LED arrays. The total number of LEDs in the string is determined by each LED's forward voltage, and the string's combined voltage must fall within the 27–54V operating range.
