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

Can the ELG-150-54AB be installed in an outdoor semi-exposed enclosure for LED lighting?

The ELG-150-54AB is rated IP65, protecting it against dust and low-pressure water jets from any direction. It is suitable for outdoor lighting enclosures in locations with indirect rain exposure, such as canopy-mounted fixture housings, but is not rated for temporary water immersion.

Is the ELG-150-54AB suitable for 54V LED strip in a hotel lobby or high-end hospitality project with dimming?

Yes. The AB suffix combines output voltage adjustment with 3-in-1 dimming (0–10V, PWM, and resistance), making it compatible with the dimming control systems typically deployed in hospitality environments. At 151.2W and 54V, it supports the extended LED strip runs common in lobby cove or wall-wash lighting.

How many meters of 54V LED strip can the ELG-150-54AB power?

The ELG-150-54AB outputs 151.2W at 54V. For a 10 W/m strip, that is approximately 15 meters; for a 15 W/m strip, approximately 10 meters. Divide 151.2W by your strip's rated power per meter and derate by 20% for reliable long-term operation.

Can I dim the ELG-150-54AB using a standard 0–10V commercial dimmer?

Yes. The 3-in-1 dimming included with the AB model accepts 0–10V, PWM, and resistance dimming signals. A standard 0–10V dimmer works directly without any additional interface hardware, making integration into commercial lighting control panels straightforward.

Is the ELG-150-54AB appropriate for powering 54V LED strips in museum or gallery display lighting?

Yes. The combination of output voltage adjustment and 3-in-1 dimming gives precise intensity control well suited to the critical lighting requirements of museum and gallery displays. The 151.2W capacity at 54V supports both high-density and lower-density 54V strip configurations.
