Test conditions and notes14

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. This series meets the typical life expectancy of >62,000 hours of operation when Tcase, particularly tc point (or TMP, per DLC), is about 70℃ or less.
10. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com.
11. 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).
12. 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
13. For A/AB type need to consider build in using to comply with Type HL application.
14. 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 use the HLG-60H-42AB to power 42V LED panel lights with dimming?

Yes. The HLG-60H-42AB delivers 42V at up to 1.45A (60.9W) and includes both output voltage/current adjustment and a 1-10V/PWM dimming input. This makes it well suited for 42V LED panels in offices, retail displays, or studios where you need precise brightness control.

Is the HLG-60H-42AB suitable for powering a small 42V LED signage installation?

Yes, provided the total sign module load stays within 60.9W. The constant-current mode operates across a 25.2-42V range, accommodating modules that may run at slightly lower voltages. The built-in dimming input also allows you to reduce sign brightness for nighttime operation or energy savings.

Can the HLG-60H-42AB drive 42V LED grow lights for a small indoor garden?

Yes, as long as the total load does not exceed 60.9W. The adjustable output lets you fine-tune voltage and current to match your specific grow light modules, and the dimming function allows you to simulate different light intensity levels during growth cycles.

How many meters of 42V LED strip can the HLG-60H-42AB support?

Divide the 60.9W rating by your strip's rated power per meter. For example, a 42V strip rated at 10W/m would allow about 6 meters (60.9W / 10W per meter). A higher-density strip at 15W/m would allow about 4 meters. Always check your strip's rated power per meter and keep the total load at or below 60.9W.

Can the HLG-60H-42AB be installed outdoors under a canopy or soffit?

Yes. The HLG-60H-42AB carries an IP65 water-resistant rating, meaning it is protected against low-pressure water jets and dust ingress. It is appropriate for sheltered outdoor locations like canopies, soffits, or covered patios. For fully exposed installations, consider the IP67-rated HLG-60H-42B instead.

What are the differences between the HLG-60H-42, 42A, 42AB, and 42B models?

All four share the same 60.9W / 42V / 1.45A core specs and a CC range of 25.2-42V. The base HLG-60H-42 has fixed output and IP67 waterproofing. The -42A adds output voltage/current adjustment via potentiometer (IP65). The -42AB adds both adjustment and 1-10V/PWM dimming input (IP65). The -42B offers dimming input only and retains IP67 waterproofing.
