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 75℃ 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-80H-42AB to power dimmable 42V LED strip lighting?

Yes. The HLG-80H-42AB outputs 42V at up to 1.95A (80W) and includes both a potentiometer for output current adjustment and a 3-in-1 dimming input (1-10V, PWM or resistance). This makes it ideal for 42V LED strips where you need smooth brightness control from an external dimmer or automation system.

Is the HLG-80H-42AB suitable for smart-home controlled 42V LED lighting?

Yes. The dimming input can be driven by smart-home lighting controllers and building automation systems that output 1-10VDC or a 10V PWM signal (100Hz-3KHz). Combined with the output current potentiometer, you get both preset tuning and dynamic brightness control for 42V LED fixtures.

Can the HLG-80H-42AB drive 42V LED architectural accent lighting?

Yes. At 80W and 42V with dimming capability, the HLG-80H-42AB is well suited for architectural cove lighting, wall washers, and accent fixtures. Its constant-current region of 25.2-42V lets it drive LED modules whose forward voltage falls within that range.

How many meters of 42V LED strip can the HLG-80H-42AB power?

Divide 80W by your strip's rated power per meter. For instance, a 42V strip consuming 10W/m allows up to 8 meters (80W / 10W per meter = 8m). Always check your strip's rated power per meter and keep total load at or below 80W.

What are the differences between the HLG-80H-42, 42A, 42AB, and 42B models?

All four share 80W / 42V / 1.95A core specs with a CC region of 25.2-42V. The base HLG-80H-42 has no adjustment or dimming and is IP67. The -42A adds output voltage/current adjustment via potentiometers (IP65). The -42AB adds output current adjustment and 3-in-1 dimming (IP65). The -42B adds the dimming input only and retains IP67.

Can I install the HLG-80H-42AB in a covered outdoor patio or carport?

Yes. Its IP65-rated metal housing is designed for indoor and outdoor applications, which suits covered outdoor areas like patios and carports. For fully exposed installations, the IP67-rated HLG-80H-42 or HLG-80H-42B would be more appropriate.
