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-54AB for dimmable 54V LED accent lighting indoors?

Yes. The AB suffix means the driver has both an output current potentiometer and a 3-in-1 dimming input (1-10V, PWM or resistance). This makes it ideal for 54V LED accent, cove, or display lighting where you need scene-level brightness control from an external dimmer or building automation system.

Is the HLG-80H-54AB suitable for 54V LED strips in a retail or hospitality setting?

Yes. At 80W and 54V with dimming capability, the HLG-80H-54AB works well for retail display cases, restaurant cove lighting, or hotel lobby accents where adjustable ambience is important. Its IP65-rated metal housing also suits kitchens and service areas with occasional moisture exposure.

Can I dim 54V LED signage remotely using the HLG-80H-54AB?

Yes. The dimming input accepts 1-10V, PWM or resistance signals, allowing remote brightness control from a timer, photocell, or building management system with a compatible output. The built-in potentiometer also lets you set the maximum output current (0.9-1.5A) to match the sign modules before connecting the dimming signal.

How many meters of 54V LED strip can the HLG-80H-54AB power?

Divide 80W by your strip's rated power per meter. For example, a 54V strip drawing 10W/m could run up to 8 meters (80W / 10W per meter = 8m). Always verify your strip's actual power per meter and keep total load at or below 80W.

Can the HLG-80H-54AB be used in a dusty warehouse or semi-outdoor covered area?

Yes. Its IP65-rated metal housing is designed for indoor and outdoor applications. Covered loading docks, dusty workshops, and covered walkways are all suitable. For direct rain exposure, the IP67-rated HLG-80H-54B is a better choice.

What are the differences between the HLG-80H-54, 54A, 54AB, and 54B models?

All four share the same 80W / 54V / 1.5A core specs. The base HLG-80H-54 has fixed output and IP67 rating. The -54A adds output voltage/current adjustment via potentiometers (IP65). The -54AB adds output current adjustment plus a 3-in-1 dimming input (IP65). The -54B provides the dimming input only and retains IP67.
