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".
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.

FAQ

Is the ELG-240-36DA-3Y rated for damp or outdoor environments?

Yes. The ELG-240 series is rated IP65 or IP67, meaning it is dust-tight and water-resistant. This makes it appropriate for damp or outdoor LED installations in signage, landscape, or architectural lighting applications.

How many meters of 36V LED strip will the ELG-240-36DA-3Y power?

This driver delivers 239.76W at 36V on 200–305VAC input (180W on 100–180VAC). For a strip rated at 14.4 W/m, the maximum run is approximately 16.6 m (239.76 ÷ 14.4). Always verify your strip's rated wattage per meter; leaving about 20% headroom is a sensible margin.

Can the ELG-240-36DA-3Y be used with DALI lighting control in commercial office fit-outs?

Yes. The DA suffix indicates DALI digital dimming support, allowing this driver to be addressed and controlled on a DALI bus. It is suitable for commercial projects where building management systems need to dim individual luminaire circuits independently.

Is this driver appropriate for 36V LED retrofit projects in hospitality venues?

Yes. The ELG-240-36DA-3Y provides 239.76W at 36V with DALI dimming, well suited for hotel or restaurant retrofits where existing DALI infrastructure controls lighting scenes. The IP65/IP67-rated housing offers added resilience in kitchen or pool-adjacent areas.

Can this driver supply 36V LED linear fixtures in healthcare or laboratory environments?

Yes, for the building lighting. The wide 100–305VAC input and DALI dimming interface make the ELG-240-36DA-3Y a practical choice for lighting retrofits in healthcare or laboratory buildings. Its 239.76W capacity supports multiple overhead LED linear fixtures, and the IP65/IP67-rated housing protects against dust and water.

What certifications does the ELG-240-36DA-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, EN55015/EN61000 EMC compliance and DALI IEC62386-101/102. These cover safety and electromagnetic compatibility requirements across North America, Europe, and several Asian markets.
