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

What does the 'A' suffix mean on the ELG-240-24A, and how does it affect use?

The 'A' suffix indicates the output voltage and current are adjustable via a built-in potentiometer, allowing fine-tuning of the output voltage from 22.4 to 25.6V and the current from 5 to 10A. This is useful when commissioning multi-zone 24V LED systems where LED forward voltages vary across fixtures.

Can the ELG-240-24A drive 24V LED strips in a hospitality cove lighting project?

Yes. At 240W and 24V with adjustable output, the ELG-240-24A suits large cove, pelmet, or under-shelf LED strip installations in hotels and restaurants. The series' IP65/IP67 rating provides protection against dust and cleaning spray in hospitality environments.

How many meters of 24V LED strip can the ELG-240-24A power?

The driver outputs 240W at 24V on 200–305VAC input (180W on 100–180VAC). For 24V strip rated at 10W per meter: 240W ÷ 10W/m = 24m at full load. With 20% headroom you get approximately 19 meters. Check your strip's rated power per meter and apply the same calculation.

Is the ELG-240-24A suitable for powering 24V LED soffit or canopy lighting outdoors?

Yes. With an IP65/IP67 rating the driver tolerates rain splash and dust in outdoor covered locations such as building soffits, canopies, and awnings. The -40°C to +90°C case temperature range (max. ambient 60°C at rated current in constant-current mode) ensures reliable performance in both winter and summer extremes.

Can the ELG-240-24A be used to supply multiple 24V LED fixtures on a single power feed?

Yes. The 240W output at 24V allows parallel connection of multiple 24V LED fixtures as long as total load stays within 240W (10A), or 180W on 100–180VAC input. The adjustable output (up to 25.6V) is useful for compensating for voltage drop over long cable runs by slightly increasing the set voltage at the driver.

What certifications does the ELG-240-24A hold for international projects?

The datasheet lists UL8750 and CSA C22.2 No. 250.13-12, IEC/BS EN/EN/AS/NZS 61347-1 and 61347-2-13, EN62384, EAC TP TC 004, BIS IS15885, GB/T19510 and KC standards; for warranty terms it refers to MEAN WELL's website. This covers North American, European, Australian, Indian, Chinese and Korean markets, making it suitable for multinational commercial lighting projects.
