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 'AB' suffix on the ELG-75-48AB indicate?

The 'AB' suffix indicates that this driver supports both output adjustment (the 'A' feature) and a built-in dimming interface (the 'B' feature). This means you can trim the 48V output and current at commissioning, and also dim the connected LEDs via an external 0–10V, PWM, or resistance signal.

Can the ELG-75-48AB be used for dimmable 48V LED strip lighting in a hospitality or hotel setting?

Yes, the ELG-75-48AB is well-suited for hospitality environments where dimming scenes are required. Its built-in dimming input allows integration with standard 0–10V lighting control systems, and its 76.8W, 48V, 1.6A output supports a practical strip lighting load for guest rooms or corridors.

Is the ELG-75-48AB suitable for outdoor signage that needs dimming capability?

Yes, for covered or protected signage enclosures. 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, so mount the driver inside the sign enclosure. The 3-in-1 dimming interface allows brightness scheduling for outdoor signs.

How many meters of 48V LED strip can the ELG-75-48AB handle?

The ELG-75-48AB delivers up to 76.8W at 48V and 1.6A on 200–305VAC input (60W on 100–180VAC). For a 48V strip rated at 9.6W/m, this allows roughly 8 meters (76.8W ÷ 9.6W/m = 8m). Confirm your strip's rated power per meter and keep total load under the rated power, especially at full brightness.

Can I control the ELG-75-48AB from a smart lighting controller for automated dimming?

Yes, the ELG-75-48AB includes a standard dimming input that accepts 0–10V, PWM, or resistance control signals, making it compatible with most smart lighting controllers and building automation systems that output these signal types. This enables programmatic dimming for scenes, schedules, or occupancy-based control.

Is the ELG-75-48AB appropriate for powering 48V LED tape in theatrical or stage display lighting?

Yes, the combination of output adjustment and dimming on the ELG-75-48AB makes it practical for theatrical display or stage backdrop lighting. The dimming interface allows smooth brightness transitions, and the 76.8W, 48V, 1.6A output handles a moderate-length strip within that wattage.
