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 I use the ELG-150-12B to power 12V LED strip lighting in an outdoor sign cabinet?
Yes. The ELG-150-12B is rated IP67, meaning it is fully sealed against dust and can withstand temporary submersion, so it is suitable for outdoor sign cabinets exposed to rain. Its 12V output matches standard 12V LED strip tape directly.
Is the ELG-150-12B suitable for powering LED strips mounted on a building facade exposed to rain?
Yes. The IP67 rating certifies this driver against water ingress from rain and splashing, making it suitable for outdoor installation. The case temperature (Tcase) range of -40°C to +90°C also accommodates most outdoor climates.
How many meters of 12V LED strip can the ELG-150-12B power?
The ELG-150-12B delivers up to 120W at 12V. Dividing 120W by your strip's rated power per meter gives the maximum run length — for example, a 14.4 W/m strip yields 120 ÷ 14.4 ≈ 8.3 m per driver. Always check your strip's rated power per meter and derate to 80% for continuous operation, which would give roughly 6.6 m for that example.
Can I use the ELG-150-12B to dim LED strips in a retail display?
Yes. The 'B' suffix indicates built-in three-in-one dimming: it accepts a 0–10VDC signal, a 10V PWM signal, or a resistance input, making it compatible with most analog dimming controllers used in retail display lighting. The minimum dimming level is about 8% of output.
Can the ELG-150-12B be used to drive LED lighting inside a food processing area that gets hosed down?
The IP67 rating covers dust and temporary water immersion up to 1 m; it does not specifically rate the driver for high-pressure jets used in some hose-down cleaning. Verify that the specific installation enclosure and wiring also meet the required ingress protection for your local safety code.
Is the ELG-150-12B a good fit for architectural LED cove lighting in a hotel lobby?
Yes. At 120W and 12V it can serve multiple short runs of 12V cove LED strip, and the built-in 3-in-1 dimming allows smooth tuning from a building management system or standard 0–10V dimmer. The enclosure is compact enough (219 × 63 × 35.5 mm) to fit within many cove cavities.
How does the ELG-150-12B compare to other 12V variants in the ELG-150 series?
The 12V models on the ELG-150 sheet share the same 120W / 10A output and enclosure: the base model (no dimming), the A variant (built-in potentiometer), the B variant (3-in-1 dimming), the AB variant (potentiometer + 3-in-1 dimming), and the DA variant (DALI dimming). Choose based on your dimming protocol; the blank, B and DA versions are IP67 while the A and AB versions are IP65.
