Test conditions and notes14

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. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
4. Tolerance : includes set up tolerance, line regulation and load regulation.
5. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
6. 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.
7. No load/standby power consumption is specified for 230VAC input.
8. 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)
9. This series meets the typical life expectancy of >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 70℃ or less.
10. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
11. 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).
12. 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
13. 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.
14. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

Can the ELG-240-24DA-3Y be used for DALI-controlled 24V LED lighting in a large commercial office?

Yes. The 'DA' suffix indicates DALI dimming, enabling individually addressed zone control and scheduling from a DALI bus. At 240W and 24V it supports extended LED strip runs across open-plan ceiling systems, which is typical in large commercial office fit-outs.

Is the ELG-240-24DA-3Y appropriate for outdoor 24V LED architectural lighting on a building facade?

Yes. The IP65/IP67 rating handles rain, the -40°C to +90°C case temperature range (max. ambient 60°C at rated current in constant-current mode) covers outdoor temperature extremes, and the 100–305VAC input accepts diverse mains supplies. DALI control allows time-scheduled dimming from a building automation system.

Can the ELG-240-24DA-3Y power 24V LED strips in an outdoor stadium or sports complex?

Yes. The IP65/IP67-rated enclosure handles the dust and moisture exposure typical of sports venue service areas and exterior concourses, and the 240W output supports long perimeter strip runs. DALI integration enables zone-level dimming control from a venue management system.

How many meters of 24V LED strip can the ELG-240-24DA-3Y support?

At 240W and 24V output (200–305VAC input), divide 240 by your strip's wattage per meter: a 14.4 W/m strip supports approximately 16.6 meters and a 20 W/m strip supports approximately 12 meters. On 100–180VAC the rating is 180W. Verify your strip's rated power per meter and consider about 20% headroom.

Is the ELG-240-24DA-3Y waterproof enough for a wet outdoor installation such as a landscape lighting vault?

Possibly. The ELG-240 series is rated IP65 or IP67, and only IP67 covers temporary water immersion, so confirm the IP rating of the unit before mounting it in below-grade enclosures or landscape vaults exposed to flooding.

What certifications does the ELG-240-24DA-3Y carry?

The datasheet lists UL8750 (type HL), CSA C22.2 No. 250.13-12, IEC/BS EN/EN/AS/NZS 61347-1 and 61347-2-13, EN62384, EAC TP TC 004, GB/T19510 and KC safety standards and DALI IEC62386-101/102. This covers North American, European, Eurasian, Australian/New Zealand, Chinese and Korean requirements, supporting broad international deployment.
