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 power supply 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-240-C1050DA be used for DALI-controlled LED downlights in a building management system?

Yes. The 'DA' suffix indicates native DALI (Digital Addressable Lighting Interface) dimming support, making this driver directly compatible with DALI-based building management and lighting control systems. It delivers 1050mA constant current with output voltages in the 114–228V range.

Is the ELG-240-C1050DA suitable for use in damp or outdoor locations?

Yes. The ELG-240-C series is rated IP65 or IP67 against dust and water, so the driver can be installed in outdoor enclosures, damp ceilings, or architectural lighting fixtures exposed to moisture. It is rated for a case temperature (Tcase) of -40°C to +85°C.

Can this driver power LED modules in a DALI-networked signage installation?

Yes. The DALI interface allows the driver to be individually addressed and scene-controlled, and with it the sign modules it powers. At 239.4W and 1050mA constant current across 114–228V, it can sustain a large series string of sign modules while supporting DALI group commands and dimming schedules.

How does the DALI dimming on the ELG-240-C1050DA differ from 0–10V dimming on the ELG-240-C1050B?

The ELG-240-C1050DA uses the DALI digital protocol (IEC62386-101/102), which allows individual driver addressing and group control (16 groups, 64 addresses) over a two-wire bus. The ELG-240-C1050B uses 0–10VDC, 10V PWM or resistance dimming, which requires an analogue control signal per driver or zone and does not support individual addressing.

How many LEDs can I run from the ELG-240-C1050DA?

The driver outputs a constant 1050mA and regulates output voltage across 114–228V. The number of LEDs in the series string depends on the forward voltage of each individual LED — divide the usable voltage range by your LED's Vf to determine the feasible string length.

Can this driver withstand installation in a rooftop or parking structure exposed to temperature extremes?

Yes. The ELG-240-C1050DA is rated for a case temperature (Tcase) of -40°C to +85°C and the ELG-240-C series is IP65/IP67-rated, making it suitable for rooftop, parking structure, and other harsh-environment LED installations where temperature swings and moisture exposure are expected.
