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
Is the ELG-150-42B waterproof enough for open outdoor LED installations?
Yes. The ELG-150-42B carries an IP67 rating, making it dust-tight and protected against water immersion up to 1 meter for 30 minutes. This qualifies it for open outdoor fixtures, facade-mounted luminaires, or exterior sign cabinets where direct rainfall is possible.
Can I use the ELG-150-42B to power 42V LED strips in outdoor architectural facade lighting?
Yes. The IP67 waterproof rating and 150W output at 42V make the ELG-150-42B well suited for outdoor facade LED strip installations. Its -40°C to +90°C case temperature (Tcase) range handles the thermal extremes found in building exterior environments; derate output at high ambient temperatures in enclosed mounting positions.
Does the ELG-150-42B include external dimming capability?
Yes. The 'B' suffix indicates 3-in-1 dimming: the DIM+/DIM- leads accept an external 0–10VDC signal, a 10V PWM signal, or a resistance, with a minimum dimming level of about 8%. It has no output-adjustment potentiometer (that is the A/AB function), and for DALI control the ELG-150-42DA would be the appropriate variant.
How much 42V LED strip can the ELG-150-42B drive?
The ELG-150-42B outputs 150W at 42V. Divide 150W by your strip's rated power per meter to find the maximum run length. For a 10 W/m strip, that is approximately 15 meters; for a 15 W/m strip, approximately 10 meters. Check your strip's rated power per meter and limit continuous load to 80%, giving roughly 12 m and 8 m respectively in those examples.
Can the ELG-150-42B be used for 42V LED strips on a pier or marine dock lighting installation?
Yes, with care. The IP67 rating provides robust protection against dust, humidity and splashing in pier or dock installations, but it does not certify corrosion resistance, so consider an additional enclosure against salt air. The 150W capacity can power significant lengths of 42V strip lighting along walkways or handrails, and the wide input range (100–305VAC) accommodates common AC supplies.
Is the ELG-150-42B appropriate for powering 42V LED strips in outdoor parking structure wayfinding lighting?
Yes. Parking structures expose LED drivers to dust, vehicle exhaust, and water from rain and washing. The IP67 waterproof and dust-tight rating of the ELG-150-42B makes it a durable choice for 42V strip-based wayfinding or overhead lighting in these environments, and its >50,000-hour typical life at Tcase ≈80°C reduces long-term maintenance concerns.
