Test conditions and notes11

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 >30,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 75℃ or less.
9. RCM is on a voluntary basis. Non IC classification Independent LED control gear is not suitable for residential installations but recommend to be used for commercial decoration/sign board/Luminaire lighting purpose.
10. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
11. 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).

FAQ

What is the Mean Well SLD-50-24 designed for?

The SLD-50-24 is a slim linear LED driver intended for 24V LED lighting applications that need up to 50.4W of output power. Its constant voltage plus constant current design makes it suitable for commercial and OEM lighting projects where a compact driver format is important.

What are the main output specifications of the SLD-50-24?

This model provides a 24V DC output with a rated current of 2.1A and a total power rating of 50.4W. Those specifications make it a fit for 24V lighting loads that stay within that voltage, current, and power range.

Does the Mean Well SLD-50-24 support dimming?

No. The listed dimming control for the SLD-50-24 is none, so it is intended for applications that do not require built-in dimming functionality from the driver itself. Buyers who need dimming should compare it with a dimmable driver series instead.

What input range does the SLD-50-24 support?

The SLD-50-24 accepts a wide 110-305VAC input range and includes PFC functionality. That broad input range helps it fit projects that need compatibility across different mains power conditions.

Is the SLD-50-24 a good choice when space is limited?

Yes. This model is built in a slim linear housing, which makes it better suited than bulkier drivers for lighting products and installations where available space is restricted. The narrow form factor is one of the main differentiators of the SLD series.

What operating temperature range is listed for the SLD-50-24?

The published temperature range for this model is -20°C to 90°C. Buyers should confirm that the intended operating environment stays within that range when evaluating it for commercial or industrial lighting use.

What warranty is provided for the Mean Well SLD-50-24?

The SLD-50-24 includes a 3-year warranty. That warranty period can be useful for B2B buyers comparing lifecycle support and long-term replacement planning across LED driver options.
