Test conditions and notes15
- 1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
- 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
- 3. Tolerance : includes set up tolerance, line regulation and load regulation.
- 4. Please refer to "DRIVING METHODS OF LED MODULE".
- 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. To fulfill requirements of the latest ErP regulation for lighting fixtures, this LED driver can only be used behind a switch without permanently connected to the mains.
- 9. For OTP which triggered at light load/no load condition, proceed AC repower on to recovery.
- 10. This series meets the typical life expectancy of >62,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 75℃ or less.
- 11. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
- 12. 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).
- 13. 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
- 14. For A/AB type need to consider build in using to comply with Type HL application.
- 15. Products sourced from the Americas regions may only have the UL, CE and UKCA logos. Please contact your MEAN WELL sales for more information.

FAQ
Can I pair with the HLG-120H-42AB to a building automation system for dimming 42V LED lights?
Yes. The HLG-120H-42AB accepts 1-10V or PWM dimming signals, so it works with building management systems and smart-lighting controllers that output these dimming signals. At 121.8W and 42V with adjustable output, it fits well into centrally controlled commercial lighting installations.
Is the HLG-120H-42AB a good choice for dimmable 42V LED cove or accent lighting indoors?
Yes. The combination of adjustable output (via potentiometer) and 1-10V/PWM dimming input gives you precise brightness control for architectural cove lighting, accent lighting, or display cases running on 42V LEDs. The 121.8W capacity supports medium-length lighting runs at 42V.
Can the HLG-120H-42AB power a dimmable 42V LED retail display lighting setup?
Yes. With 121.8W at 42V, dimming capability, and adjustable output, the HLG-120H-42AB lets you fine-tune brightness for retail displays, showcases, or merchandising illumination. The 90-305VAC input handles worldwide mains, and the IP65 rating suits indoor and sheltered commercial environments.
How many meters of 42V LED strip can the HLG-120H-42AB handle?
The HLG-120H-42AB provides up to 121.8W at 42V. For a strip rated at 14.4W/m, you could run approximately 8.5 meters (121.8W / 14.4W per meter). Always check your strip's rated power per meter and keep total load at or below 121.8W.
Can the HLG-120H-42AB be used in a dusty workshop or manufacturing floor?
Yes. The IP65 rating provides complete protection against dust ingress and low-pressure water jets. This makes it suitable for workshops and light manufacturing environments where airborne dust is present. For wet or fully exposed outdoor locations, choose an IP67-rated model instead.
