Test conditions and notes13

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". For DA-Type, Constant Current region is 60%~100% of maximum voltage under rated power delivery.
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. 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)
8. 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.
9. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
10. 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).
11. 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
12. 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.
13. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

Can the ELG-100-24DA be installed outdoors in a wet environment?

Yes. The ELG-100-24DA carries an IP67 waterproof rating, making it suitable for outdoor installations where it may be exposed to rain or splashing. It can be mounted in outdoor lighting enclosures or sign boxes; follow the IP installation cautions in MEAN WELL's user manual.

Is the ELG-100-24DA a good choice for powering 24V LED strip in architectural cove lighting?

Yes. The 24V output and 96W power rating support continuous 24V LED strip runs used in architectural cove and accent lighting. The wide input range of 100–305VAC accommodates both 120V and 277V commercial electrical systems in North America; on 120V (100–180VAC) the rating is 70W.

How long a run of 24V LED strip can the ELG-100-24DA support?

The ELG-100-24DA provides 96W at 24V on 200–305VAC input (70W on 100–180VAC, e.g. 120VAC). At 96W, a 14.4 W/m strip allows approximately 6.6 meters (96 ÷ 14.4); a 9.6 W/m strip, up to 10 meters. Always verify your strip's rated power per meter and leave a 20% safety margin to prevent overloading.

Does the ELG-100-24DA support DALI dimming, and what lighting control systems is it compatible with?

Yes. The DA suffix indicates this model supports DALI dimming, with compliance to IEC62386-101 and 102 (207 by request), 16 groups and 64 addresses. It is compatible with DALI controllers, DALI wall controls, and BMS platforms that use DALI for centralized LED dimming.

Can I use the ELG-100-24DA to drive 24V LED lighting in a refrigerated display case?

Yes. The -40°C to +90°C case temperature (Tcase) rating means this driver can operate in cold-storage and refrigeration environments. Its working humidity rating is 20–95% RH non-condensing, so mount it where condensation from warm air meeting cold surfaces will not form on the driver.

What certifications does the ELG-100-24DA hold, and which markets does it cover?

The datasheet lists UL8750 (Type HL) and CSA C22.2 No. 250.13-12 (North America), IEC/BS EN/EN/AS/NZS 61347-1 and 61347-2-13 and EN62384 (Europe, UK, Australia/New Zealand), EAC TP TC 004 (Eurasia), GB/T19510 (China), BIS IS15885 (India) and KC (Korea), plus EN55015/EN61000/EN61547 EMC compliance, making it suitable for multi-region projects.
