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-100-24A be used outdoors in a rain-exposed installation?

The ELG-100-24A is rated IP65, which means it is protected against low-pressure water jets from any direction—suitable for most outdoor lighting fixtures and sign cabinets with splash exposure. It is not rated for temporary immersion like the IP67 version.

How many meters of 24V LED strip can the ELG-100-24A power?

With 96W at 24V (200–305VAC input; 70W on 100–180VAC, e.g. 120VAC), divide the wattage by your strip's power per meter. At 96W, for a 14.4 W/m strip: 96 ÷ 14.4 = approximately 6.6 meters. For a 9.6 W/m strip: 96 ÷ 9.6 = 10 meters. Always check your strip's rated power per meter and apply a 20% derating for thermal safety.

What does the 'A' suffix on the ELG-100-24A mean, and how does it affect LED lighting use?

The 'A' suffix indicates the ELG-100-24A includes a built-in potentiometer for adjusting the output voltage (21.6–26.4V) and output current (2–4A). For LED lighting, this allows fine-tuning brightness or compensating for long cable runs where slight voltage drop occurs.

Can I use the ELG-100-24A to drive 24V LED strip in a covered outdoor walkway?

Yes. The ELG-100-24A's IP65 rating handles water spray typical of covered walkways or pergola installations. Its -40°C to +90°C case temperature (Tcase) rating accommodates seasonal temperature extremes in outdoor settings, with load derating at high temperatures.

Is the ELG-100-24A suitable for powering LED backlighting in outdoor menu boards or digital signage?

Yes. At 96W and 24V with IP65 protection, it is well suited to powering LED backlighting in menu boards or signage enclosures exposed to weather. The adjustable output lets integrators dial in the exact voltage needed for the installed LED backlight modules.

Can the ELG-100-24A power LED cove lighting in a commercial building lobby?

Yes. The 96W / 24V output is appropriate for continuous cove lighting runs in commercial interiors. The output adjustment feature lets installers fine-tune brightness to the desired level without replacing the driver.
