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

FAQ
What does the 'DA' suffix mean on the ELG-75-48DA, and how is it different from the 'B' type?
The 'DA' suffix indicates the ELG-75-48DA includes a DALI (Digital Addressable Lighting Interface) dimming interface compliant with IEC 62386-101/102, a digital protocol widely used in commercial building automation. Unlike the 'B' type, which accepts 0–10V, 10V PWM or resistance signals, the DA type communicates over a two-wire DALI bus (DA+/DA-), enabling addressable and group-based control.
Can the ELG-75-48DA be integrated into a DALI-based building management system for 48V LED lighting?
Yes, the ELG-75-48DA is designed for DALI systems. It can be addressed and controlled individually or as part of a group via a DALI controller or BMS, allowing scene recall, occupancy-based dimming, and daylight harvesting for 48V LED installations up to 76.8W.
Is the ELG-75-48DA suitable for outdoor DALI-controlled LED signage or architectural lighting?
Yes. The ELG-75 series carries an IP65 or IP67 rating, making the ELG-75-48DA suitable for outdoor architectural lighting and signage that requires DALI control. Its -40°C to +85°C case-temperature range supports year-round outdoor deployment.
How many meters of 48V LED strip can the ELG-75-48DA power?
The ELG-75-48DA delivers up to 76.8W at 48V and 1.6A on 200–305VAC input (60W on 100–180VAC). For a 48V strip rated at 10W/m, this supports approximately 7.6 meters (76.8W ÷ 10W/m ≈ 7.6m). Check your specific strip's rated power per meter and keep total load under the rated power.
Can the ELG-75-48DA be used in a DALI-controlled 48V LED troffer or luminaire in a commercial office?
Yes, the ELG-75-48DA is well-suited for commercial office luminaires requiring DALI control. At 76.8W, 48V, and 1.6A, it can drive a 48V LED engine within a troffer or recessed fixture, and its DALI interface (IEC 62386-101/102, 16 groups and 64 addresses) enables digital dimming and group addressing.
Does the ELG-75-48DA work in cold outdoor climates for DALI-controlled landscape lighting?
Yes. The ELG-75-48DA is rated down to -40°C case temperature and the series is IP65/IP67-rated, making it appropriate for cold-climate outdoor landscapes where DALI control is needed for automated dimming at different times of night or seasonal schedules.
Can the ELG-75-48DA replace a non-DALI driver in an existing 48V lighting retrofit?
The ELG-75-48DA outputs 48V at up to 1.6A constant current (76.8W), so it can replace a non-DALI driver with matching voltage and power ratings. Adding the DALI interface requires a DALI controller or bus already present in the circuit; if no DALI infrastructure exists, a simpler 'A' or 'B' type driver may be more appropriate.
