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-150-54 be mounted outdoors in a rain-exposed signage installation?

Yes. The ELG-150-54 is rated IP67, meaning it is fully sealed against dust ingress and can withstand temporary water immersion. It can be installed inside outdoor sign cabinets, facade-mounted enclosures, or ground-level housings exposed to rain without additional weatherproofing.

Is the ELG-150-54 suitable for powering 54V LED strip in large-format architectural cove lighting?

Yes. The 54V output and 151.2W total power make this driver a strong match for high-density 54V LED strip runs in architectural cove or valance installations. The constant-current mode with a 27–54V CC range gives consistent current through the LED load as voltage varies across the strip.

Can this driver power 54V LED strip in an outdoor LED channel letter installation?

Yes. The ELG-150-54 combines IP67 waterproof protection with 151.2W at 54V, which handles the power demand of mid-size 54V channel letter arrays. Its compact 219 × 63 × 35.5 mm housing suits sign installations; check the internal space of your raceway before specifying.

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

The ELG-150-54 delivers 151.2W at 54V. Divide 151.2W by your strip's rated power per meter—for example, a 10 W/m strip allows approximately 15 meters, and a 15 W/m strip allows approximately 10 meters. Always check your strip's rated power per meter and apply a 20% derating margin for thermal reliability.

Is the ELG-150-54 appropriate for LED strip lighting in cold-storage or freezer environments?

Yes. With a case temperature (Tcase) range of -40°C to +90°C, this driver starts and runs reliably in cold-storage and freezer applications. The IP67 sealed enclosure protects against moisture, but the sheet specifies 20–95% RH non-condensing working humidity, so avoid spots where condensation forms on the driver.

What is the difference between the ELG-150-54 and the ELG-150-54B in this series?

Both the ELG-150-54 and ELG-150-54B output 151.2W at 54V / 2.8A with IP67 protection and a 27–54V CC range. The key difference is that the ELG-150-54B adds 3-in-1 dimming (0–10V, PWM, and resistance), while the ELG-150-54 has no dimming control. Choose the base model when dimming is not required.
