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 does the 'A' suffix on the ELG-75-48A mean, and why would I choose it over the base model?
The 'A' suffix indicates the ELG-75-48A includes a built-in potentiometer for output voltage (43.2–52.8V) and current (0.8–1.6A) adjustment. This is useful when commissioning a lighting system where minor trimming is needed to match load requirements precisely.
Can the ELG-75-48A be used for indoor office accent lighting with 48V LED strips?
Yes. The ELG-75-48A is a good fit for 48V LED strip runs in office cove, under-cabinet, or accent applications. Its 76.8W capacity at 1.6A handles a typical accent lighting load, and the adjustment feature allows on-site calibration to match the installed strip's requirements.
Is the ELG-75-48A waterproof enough for use in a bathroom or wet room?
The ELG-75 series is rated IP65 or IP67, which is generally sufficient for damp locations and splash-prone areas, though the datasheet gives no submersion rating. It also notes that A types need to be built in to comply with Type HL application, so install the driver inside a fixture or enclosure, away from any risk of immersion.
How many meters of 48V LED strip can the ELG-75-48A drive?
The ELG-75-48A provides up to 76.8W at 48V and 1.6A on 200–305VAC input (60W on 100–180VAC). A 48V strip rated at 12W/m would allow about 6.4 meters (76.8W ÷ 12W/m ≈ 6.4m). Always verify your strip's rated power per meter and leave a small headroom below the rated maximum.
Can the ELG-75-48A power LED strips in museum display cases or gallery lighting?
Yes, the adjustable output on the ELG-75-48A makes it useful for gallery and museum display lighting where precise brightness calibration is important. At 76.8W and 48V constant-voltage/constant-current operation, it suits contained 48V strip or module installations in display cases.
Does the ELG-75-48A support outdoor use in a covered patio or building facade?
Yes, for covered outdoor areas like patios or facade recesses. The ELG-75 series is rated IP65 or IP67, and the datasheet notes A types need to be built in to comply with Type HL application, so mount the driver inside a fixture or weatherproof enclosure.
Can I use the ELG-75-48A to drive 48V LED panels in a suspended ceiling grid?
Yes, the ELG-75-48A at 76.8W, 48V, and 1.6A can supply a 48V LED panel load within that wattage envelope. The ability to trim the output makes it practical for matching the driver output to panel specifications that may vary slightly. Ensure the total panel draw stays within 76.8W.
