Test conditions and notes14
- 1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
- 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. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
- 4. Tolerance : includes set up tolerance, line regulation and load regulation.
- 5. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTICS” sections for details.
- 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. 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. 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. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com.
- 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. 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. 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. 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. For A/AB type need to consider build in using to comply with Type HL application.

FAQ
Can the ELG-150-12A be used in a semi-outdoor installation such as a covered parking structure?
The ELG-150-12A carries an IP65 water-resistant rating, which protects against low-pressure water jets and dust but is not fully waterproof for immersion. A covered parking structure that prevents direct rain contact is appropriate; locations with standing water or regular hosing would call for an IP67 variant such as the ELG-150-12B.
Is the ELG-150-12A a good choice for powering dimmable 12V LED strips in a retail store with adjustable accent lighting?
Partly. The A suffix indicates a built-in potentiometer that adjusts output voltage (10.8–13.2V) and current (5–10A), allowing on-site calibration of brightness, but it has no external dimming input; for dimmer control choose the ELG-150-12B or 12AB. At 120W and 10A, it can supply substantial 12V LED strip runs across a retail floor plan.
How much 12V LED strip can the ELG-150-12A drive in a single run?
The driver delivers 120W at 10A. For a 12V strip rated at 14.4 W/m, that supports approximately 8.3 m of strip (120 W ÷ 14.4 W/m). For a higher-density 20 W/m strip, the supported run drops to about 6 m. Check the strip's rated power per meter and leave a 10–20% derating margin for thermal stability.
Can I use the ELG-150-12A to power 12V LED strip in a hospitality lounge with adjustable ambient lighting?
Yes. The adjustable current output on the A model allows an installer to set the drive current—and therefore brightness—to suit the designed lux level without separate external dimmers. This is useful in hospitality environments where final tuning happens during commissioning. The wide input range (100–305VAC) supports international installations.
Is the ELG-150-12A suitable for powering LED strips in a museum showcase with precise light level requirements?
Yes. The adjustable output current allows fine-tuning during commissioning to set accurate illuminance levels at each showcase, avoiding the need for additional inline resistors or external dimmers. Its >50,000-hour typical life at Tcase ≈80°C suits permanent exhibition installations.
Does the ELG-150-12A operate reliably in high-ambient-temperature environments such as enclosed sign cabinets in summer?
Yes, within limits. The driver's maximum case temperature (Tcase at the tc point) is +90°C, and output must be derated at high ambient temperatures per the sheet's output load vs temperature curve. Adequate ventilation or thermal management in a sealed sign cabinet is recommended, and keeping Tcase around 80°C or less supports the >50,000-hour typical life.
