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". For DA-Type, Constant Current region is 60%~100% of maximum voltage under rated power delivery.
  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 CHARACTERISTICS” 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. 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. 8. This series meets the typical life expectancy of >50,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 80℃ or less.
  9. 9. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com.
  10. 10. 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).
  11. 11. 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
  12. 12. 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.
  13. 13. ELG-150-12(except blank/A-Type) is used for any light source that exempt from the ErP-Directive (EU) 2019/2020 requirement, for example this model could be use for signalling products(including, but not limited to road-, railway-, marineorair traffic-signalling , traffic control or airfield lamps) .
  14. 14. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

What is the output rating of the Mean Well S-ELG-150-12 power supply?

This model provides a 12V DC output with a rated current of 10A. Its listed power rating is 120W (84W at 100–180VAC input), making it suitable for 12V loads that need a stable constant-voltage + constant-current supply within that capacity.

What kinds of applications is this 12V Mean Well power supply designed for?

It is an LED driver, suited to LED lighting applications such as signage, architectural and street lighting. It is intended for commercial or trade use where a reliable 12V power supply is needed for compatible lighting systems.

Does this model support dimming control?

No. The listed dimming control for this model is none, so it is not presented as a dimmable power supply in the provided product data.

What input range does the Mean Well S-ELG-150-12 support?

It supports a wide 100 to 305VAC input range and 142 to 431VDC. That broad input range makes it suitable for environments where mains supply conditions may vary; note that output power is derated to 84W below 180VAC.

How efficient is this power supply?

The sheet lists a typical efficiency of 88.5% for the 12V model. It also states no-load power consumption is less than 0.5W, which can be beneficial in applications where standby energy use matters.

What protection features are included in this model?

The sheet lists over current, short circuit, over voltage (14–18V), and over temperature protection. These built-in protections are intended to help safeguard the power supply during abnormal operating conditions.

What operating temperature range is listed for this power supply?

The sheet lists a working case temperature (Tcase) range from -40°C to +90°C, with output derating at higher ambient temperatures. Buyers should review their application requirements carefully to confirm that this range aligns with the intended operating environment.

What warranty comes with the Mean Well S-ELG-150-12?

The spec sheet does not state a warranty period; it refers to the warranty statement on MEAN WELL's website. Check that statement for the current coverage terms for this power supply model.
