Test conditions and notes11

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
2. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
3. 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.
4. 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.
5. This series meets the typical life expectancy of >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 75℃ or less.
6. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
7. 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).
8. It is not recommended to connect to capacitive loads.
9. Flicker is measured at full load with the light source provided by MEAN WELL.
10. RCM is on a voluntary basis. Non IC classification Independent LED control gear is not suitable for residential installations.
11. Based on IEC 62368-101/102 DALI power on timing and interruption regulations, the set up time needs to test with a DALI controller which can support for DALI power on function, otherwise the set up time will be higher than 0.5 second for DA2 type

FAQ

What type of lighting applications is the MEAN WELL SPWM-75-24DA2 designed for?

This model is designed for professional constant-voltage LED lighting applications that need 24V DC output and dimming control. It is a practical fit for commercial or architectural lighting projects where integration with digital lighting control is important.

Does the SPWM-75-24DA2 support DALI dimming?

Yes. The SPWM-75-24DA2 includes DALI-2 DT6 dimming support, which makes it suitable for lighting systems that use DALI-based control and automation. It also supports PUSH dimming for projects that need an additional dimming control option.

What are the main electrical ratings of the SPWM-75-24DA2?

This LED driver provides a 24V constant-voltage output with a rated current of 3.2A. Its listed power rating is 76.8W, making it suitable for 24V LED loads within that output range.

How does the SPWM-75-24DA2 compare with a non-dimming 24V LED driver?

The key difference is control capability. This model adds DALI-2 DT6 and PUSH dimming support, so it is better suited to lighting projects that need adjustable brightness and integration into managed lighting systems, while still delivering 24V constant-voltage output.

Is the SPWM-75-24DA2 suitable for demanding temperature environments?

This model is rated for operation from -20°C to +90°C case temperature, which gives it a broad working temperature range for challenging indoor or protected commercial environments. Buyers should still confirm the full project conditions and enclosure design are appropriate for the application.

What warranty is offered for the SPWM-75-24DA2?

This model is listed with a 5-year warranty period. That can be an important consideration for professional lighting projects where long-term reliability and maintenance planning matter.
