Test conditions and notes14
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
  2. 2. Please refer to "DRIVING METHODS OF LED MODULE".
  3. 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. 4. Tolerance : includes set up tolerance, line regulation and load regulation.
  5. 5. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
  6. 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. 7. No load/standby power consumption is specified for 230VAC input.
  8. 8. 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)
  9. 9. 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.
  10. 10. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com

  12. 12. 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
  13. 13. To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED power supply can only be used behind a switch without permanently connected to the mains.
  14. 14. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

What is the Mean Well S-ELG-240-24 used for?

The Mean Well S-ELG-240-24 is a 240W, 24V LED driver suited to LED lighting and street lighting applications. It is a constant-voltage plus constant-current model for buyers who need a 24V DC output with industrial-grade input tolerance and protection features.

What output does this power supply provide?

This model provides a 24V DC output with a rated current of 10A, for a total power rating of 240W on 200–305VAC input (180W on 100–180VAC). That makes it suitable for 24V systems that need higher output capacity from a single supply.

Does the S-ELG-240-24 support dimming?

No. This is the base (no letter suffix) ELG-240-24 version, which has no dimming interface. Buyers needing integrated dimming control should compare it against a B, AB or DA variant rather than assume this unit includes that function.

What input range does this model support?

The S-ELG-240-24 has a wide AC input range of 100 to 305VAC, and it also lists a DC input range of 142 to 431VDC. This broad input tolerance is useful for commercial and project-based applications where supply conditions may vary.

Is this power supply suitable for demanding environments?

This model is specified for a case temperature (Tcase) of -40°C to +90°C, with a maximum ambient of 60°C at rated current in constant-current mode. It also includes over current, short circuit, over voltage, and over temperature protections, which makes it better suited to demanding operating conditions than basic indoor-only supplies.

What efficiency and standby performance does this model offer?

Mean Well lists a typical efficiency of 92% for the 24V model (up to 93% across the ELG-240 series). It also has no-load power consumption below 0.5W, which can help reduce standby energy use in systems where efficiency matters.

What warranty is included with the Mean Well S-ELG-240-24?

The datasheet does not state a warranty period; it refers to the warranty statement on MEAN WELL's website (www.meanwell.com). For B2B buyers, check that statement when comparing lifecycle value and supplier support across project components.
