Test conditions and notes13
- 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 CHARACTERISTIC” 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. For A/AB type need to consider build in using to comply with Type HL application.

FAQ
Can the ELG-100-42AB dim LED strips using a standard 0–10V dimmer?
Yes. The ‘B’ function in the ELG-100-42AB supports 3-in-1 dimming: 0–10VDC analogue, 10V PWM signal, and resistance dimming. This means it is compatible with common 0–10V wall dimmers and lighting control panels used in architectural and retail LED installations.
What is the IP rating of the ELG-100-42AB and where can it be installed?
The ELG-100-42AB is rated IP65, providing full dust protection and resistance to water jets from any direction. It is suitable for covered outdoor locations, semi-exposed areas under canopies, and indoor damp areas such as car parks and food service facilities.
Can I use the ELG-100-42AB to power a dimmable 42V LED strip in a hospitality lighting project?
Yes. The combination of output adjustment (‘A’) and 3-in-1 dimming (‘B’) makes the ELG-100-42AB practical for hospitality environments where adjustable light levels are required. It delivers up to 95.76W at 42V, and its potentiometer adjusts output voltage within 37.8–46.2V and current within 1.14–2.28A to match the fixture.
How much 42V LED strip can the ELG-100-42AB drive?
With a maximum output of 95.76W at 42V (200–305VAC input; 70W on 100–180VAC), the ELG-100-42AB can supply approximately 9.5 meters of strip rated at 10W per meter. Always check your strip’s rated power per meter and apply a derating margin; the actual length supported will vary based on strip wattage.
Can the ELG-100-42AB be used for museum or gallery accent lighting with dimming control?
Yes. The driver’s 3-in-1 dimming compatibility and output adjustability make it suitable for accent lighting in museums and galleries where precise light level control is required. Its 95.76W / 42V output supports medium-wattage 42V LED fixtures used in directional accent applications.
Does the ELG-100-42AB accept international mains voltages?
Yes. It accepts 100–305VAC, covering 120V, 230V, and 277V mains without manual switching; the rated power is 70W at 100–180VAC and 95.76W at 200–305VAC. This makes it suitable for international projects or installations where supply voltage varies across circuits.
