Test conditions and notes13
  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 β€œSTATIC 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) .

FAQ

Can I integrate the ELG-150-12DA into a DALI-based smart lighting system?

Yes. The 'DA' suffix indicates DALI protocol dimming, allowing the driver to be individually addressed and controlled by a DALI lighting management system. This is suitable for office, hospitality, or retail installations using centralized scene control.

Is the ELG-150-12DA suitable for powering outdoor architectural LED strip lighting?

Yes. The IP67 waterproof rating protects the driver against rain and temporary water exposure, and the -40Β°C to +90Β°C case temperature (Tcase) range covers outdoor use in most climates. At 12V it is compatible with standard outdoor-rated 12V LED strip products.

How much 12V LED strip can the ELG-150-12DA drive?

The ELG-150-12DA supplies 120W at 12V. For a 12 W/m strip: 120 Γ· 12 = 10 m maximum; at 80% derating for continuous duty that is 8 m. Check your specific strip's rated power per meter for an accurate calculation.

Can the ELG-150-12DA be used for theatre stage wash lighting that needs smooth dimming?

Yes. DALI dimming provides digitally controlled dimming down to a minimum of about 8% output, which suits theatre stage applications that use scene programming. The driver outputs 120W at 12V, compatible with LED strip or module fixtures used in wash lighting.

Is the ELG-150-12DA rated for installation in a wet outdoor location?

The IP67 rating certifies the enclosure against dust ingress and temporary immersion in up to 1 m of water, which suits wet outdoor locations. Always confirm with your local authority having jurisdiction that the driver installation method meets site-specific requirements.
