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 62386-101/102 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 SPWM-240-48DA2 designed for?

The MEAN WELL SPWM-240-48DA2 is intended for professional constant-voltage LED lighting systems that require controlled dimming. Its 48V output and 240W power rating make it suitable for higher-power LED applications where stable brightness control and commercial-grade reliability are important.

Does this LED driver support DALI lighting control?

Yes. This model supports DALI-2 DT6 digital dimming, which is used in professional lighting control systems that need consistent and precise brightness adjustment. It is a strong fit for projects where centralized dimming and interoperable lighting control are required.

Can the SPWM-240-48DA2 be used with push dimming systems?

No. The DA2 model supports DALI-2 DT6 digital dimming only. PUSH dimming is a feature of the BLANK type (3-in-1 dimming), not the DA2 type. Buyers requiring push dimming should select the BLANK version of this series.

What are the main output specifications of this model?

The SPWM-240-48DA2 is a constant-voltage LED driver rated for 240W output at 48V. Its rated current is 5.0A, which aligns with its use in 48V LED lighting systems that need substantial output capacity.

Is this model suitable for emergency lighting or central battery system projects?

Yes. The product description states that DA2 models support DC input in addition to AC input, which helps with compatibility in emergency lighting and central battery system applications. That makes this version more versatile than drivers limited to AC-only operation.

What operating temperature range should buyers consider for this LED driver?

This model is specified with a case temperature range from -20°C to +90°C. That range supports use in demanding lighting environments, but buyers should still confirm that the surrounding application conditions stay within the product's stated limits.
