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-150-48B be mounted in a wet or rain-exposed outdoor location?
Yes. The ELG-150-48B is rated IP67, meaning it is fully protected against dust and temporary water immersion. It can be installed in outdoor luminaires, weatherproof junction boxes, or sign cabinets where direct water contact is possible.
How many meters of 48V LED strip can the ELG-150-48B power?
The ELG-150-48B provides 150.2W at 48V. At 10 W/m, that supports approximately 15 meters of strip; at 15 W/m, approximately 10 meters. Divide 150.2W by your strip's rated wattage per meter and apply a 20% derating for reliable thermal performance.
Is the ELG-150-48B suitable for 48V LED strip in outdoor landscape feature lighting?
Yes. The IP67 rating and -40°C to +90°C case temperature (Tcase) range make the ELG-150-48B well suited for landscape feature or tree uplighting where the driver may be housed in ground-level enclosures subject to rainwater pooling. The 48V output also reduces current and allows longer cable runs compared to 24V systems.
Does the ELG-150-48B support PWM dimming for integration with smart lighting systems?
Yes. The 'B' suffix indicates 3-in-1 dimming supporting 0–10V, 10V PWM (100Hz–3kHz), and resistance dimming signals. PWM dimming is commonly used by smart lighting controllers, allowing the ELG-150-48B to integrate directly into automated or occupancy-responsive lighting systems.
Can I use the ELG-150-48B to power 48V LED strips for outdoor retail facade lighting?
Yes. With 150.2W at 48V and IP67 protection, this driver handles the power demands of large outdoor facade LED installations while tolerating the moisture and temperature extremes of exterior environments. The 3-in-1 dimming accepts the 0–10V, PWM, or resistance signals used in many retail facade control systems (DALI requires the DA model).
How does the ELG-150-48B differ from the ELG-150-48AB in this series?
The ELG-150-48B (150.2W, 48V, 3.13A) is IP67 rated and provides 3-in-1 dimming only. The ELG-150-48AB (150.2W, 48V, 3.13A) is IP65 rated and combines both output voltage adjustment and 3-in-1 dimming. Choose the B when full waterproofing is the priority; choose the AB when adjustment plus dimming flexibility is needed in a splash-protected location.
