Test conditions and notes12

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 of >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 70℃ 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. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

What dimming methods does the ELG-75-24AB support?

The AB suffix indicates this driver combines the A variant's output-voltage potentiometer with the B variant's 3-in-1 dimming interface (PWM signal, 0–10V analog, and resistance dimming). This makes it compatible with a wide range of dimmers, including 0–10V wall dimmers and PWM controllers commonly used with 24V LED strip.

Can the ELG-75-24AB be installed in a covered outdoor enclosure for 24V LED strip signage?

Yes. The ELG-75 series is rated IP65 or IP67, and the datasheet notes AB types need to be built in to comply with Type HL application. It is suitable for sign enclosures and covered outdoor locations, but the datasheet gives no submersion rating, so avoid any risk of immersion.

How many meters of 24V LED strip can the ELG-75-24AB power?

The ELG-75-24AB delivers 75.6W at 24V on 200–305VAC input (60W on 100–180VAC). For a 10 W/m strip that allows up to 7.5 meters; for a 14.4 W/m strip, approximately 5.25 meters. Check your strip's rated power per meter and apply a 20% safety margin for continuous operation.

Is the ELG-75-24AB a good choice for a dimmable 24V LED strip installation in a retail or hospitality setting?

Yes. The 3-in-1 dimming interface and output voltage adjustment make the ELG-75-24AB flexible for retail and hospitality installations where lighting scenes and brightness levels must be tuned. It works with 0–10V wall dimmers, PWM controllers, and resistance dimmers already in place in many commercial spaces.

Can the ELG-75-24AB drive 24V LED strip used in office cove or indirect ceiling lighting with smart dimming control?

Yes. The 0–10V dimming input on the ELG-75-24AB is compatible with many smart lighting and BMS systems used in office environments for energy management. At 75.6W and 24V, it supports moderate-length cove or indirect ceiling strip installations in open-plan offices or meeting rooms.

What is the operating temperature range for the ELG-75-24AB, and does it suit warm ceiling plenums?

The ELG-75-24AB is rated for a case temperature (Tcase) of -40°C to +85°C, with load derating at higher ambient temperatures per the datasheet curve. In warm ceiling plenums where ambient temperatures may be elevated due to HVAC equipment or solar gain, ensure sufficient airflow around the driver enclosure to keep the case temperature within this rated limit.
