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 LED lighting is the MEAN WELL SPWM-75-24 designed for?

The SPWM-75-24 is a constant voltage LED driver built for 24V LED strip lighting applications. Its PWM-style output is intended to support stable brightness and consistent colour performance in those systems. This model is not a constant current driver.

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

This model provides a 24V DC output and is rated for 3.2A, with a total power rating of 76.8W. It operates from a wide 100-305VAC input range and includes active power factor correction. These specifications make it suitable for constant-voltage LED loads that match its output rating.

What dimming methods does the MEAN WELL SPWM-75-24 support?

The SPWM-75-24 supports 0-10V dimming, 10V PWM dimming, and resistance-based dimming control. That gives buyers flexibility when selecting a compatible dimming method for a commercial or architectural lighting project. The supported dimming types are specific to this model's listed control options.

Can the SPWM-75-24 be used in demanding temperature conditions?

The SPWM-75-24 is specified for operation from -20°C to +90°C case temperature. It uses a fanless, free-air convection design, which can be useful where low maintenance and silent operation are preferred. Buyers should still confirm that the full operating environment stays within the product's rated temperature range.

Why would a buyer choose the SPWM-75-24 instead of a 12V version in the same series?

The SPWM-75-24 is the 24V version, so it is intended for lighting systems that require a 24V constant-voltage output. Compared with a 12V variant, the key difference is the output voltage, which needs to match the voltage requirement of the LED load. This model's rated output is 24V at 3.2A.

What product features make the SPWM-75-24 suitable for professional LED projects?

The SPWM-75-24 combines active PFC, up to 90% efficiency, flicker-free operation, and a slim plastic housing in a 75W-class LED driver. It is backed by a 5-year warranty and weighs 0.31 kg, which can help when evaluating specification-driven projects. These details make it a practical option for buyers looking for a branded constant-voltage LED driver with dimming support.
