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. 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 >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is 70℃ or less.
9. RCM is on a voluntary basis. Non IC classification Independent LED control gear is not suitable for residential installations.
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. To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED driver can only be used behind a switch without permanently connected to the mains.
13. 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
14. This series need to consider build in using to comply with Type HL application.

FAQ

Can the ELG-300-24A drive 24V LED strip lighting in large commercial or retail environments?

Yes. The ELG-300-24A outputs 300W at 24V with a 12.5A rated current on 200–305VAC input (255W / 10.63A on 100–180VAC), which is well suited for extended 24V LED strip runs in retail shelf lighting, hotel corridor lighting, or large architectural installations. The high wattage allows a single driver to power a substantial section of a lighting system.

How many meters of 24V LED strip can the ELG-300-24A support?

The ELG-300-24A delivers 300W at 24V on 200–305VAC input (255W on 100–180VAC). At 300W, a 10 W/m strip supports approximately 30 meters (300 ÷ 10) and a 14.4 W/m strip approximately 20.8 meters; at 255W, approximately 25.5 and 17.7 meters. Always check your strip's rated power per meter and leave some headroom.

Is the ELG-300-24A suitable for outdoor 24V LED lighting in wet or coastal environments?

Yes. The IP67 rating protects against dust ingress and temporary water immersion, and the working case temperature (Tcase) range of -40°C to +85°C covers outdoor temperature extremes, with output derating at higher temperatures. These characteristics make it appropriate for outdoor area lighting, facade uplighting, or waterfront signage.

Can the ELG-300-24A be used for 24V LED lighting in industrial or manufacturing facility applications?

Yes. IP67 protection and the 100–305VAC wide input range allow installation in industrial environments with humidity, dust, or variable mains voltage (derating may be needed at low input voltage). The 300W output at 24V (255W on 100–180VAC) supports high-lumen LED luminaires or large strip arrays used in factory and warehouse lighting.

What does the 'A' suffix indicate on the ELG-300-24A, and how does adjustment work?

The A type has adjustable output voltage and current. The voltage can be set within 22.4–25.6V and the current within 6.25–12.5A, allowing the output to be fine-tuned to match specific LED loads or to compensate for voltage drop over long cable runs without external components.

Is the ELG-300-24A appropriate for powering 24V LED lighting in museum or gallery display cases?

Yes. The adjustable output allows precise tuning to the LED load requirements typical of display case luminaires, and the IP67 housing and typical life expectancy above 50,000 hours (at Tcase 70°C or less) support long-term operation. With safety approvals including UL8750, ENEC and CSA, it suits permanent exhibition installations; see MEAN WELL's website for the warranty statement.
