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-48A to power adjustable 48V LED strip lighting?

Yes. The HLG-80H-48A delivers 48V at up to 1.7A (80W) and features built-in potentiometers to trim output voltage (43-53V) and current (1.02-1.7A). This lets you fine-tune the drive level for 48V LED strips in retail, exhibition, or architectural applications.

Is the HLG-80H-48A suitable for 48V LED signage where output tuning is needed?

Yes. The adjustable output lets you match the driver precisely to your 48V sign module string voltage, avoiding over-driving. At 80W with wide 90-305VAC input, it handles commercial mains supplies and can power 48V channel letters or light-box modules.

Can the HLG-80H-48A drive 48V LED fixtures in a commercial ceiling installation?

Yes. At 80W and 48V with adjustable output, it suits ceiling-mounted 48V LED troffers or linear fixtures. The potentiometers are convenient for matching different fixture loads during commissioning without needing an external dimmer. Its IP65-rated metal housing suits dusty or damp locations above the ceiling.

How many meters of 48V LED strip can the HLG-80H-48A support?

Divide 80W by your strip's rated power per meter. For example, a 48V strip rated at 16W/m allows up to 5 meters (80W / 16W per meter = 5m). Always check your strip's rated power per meter and keep total load at or below 80W for reliable operation.

What are the differences between the HLG-80H-48, 48A, 48AB, and 48B models?

All four share 80W / 48V / 1.7A core specs with a CC region of 28.8-48V. The base HLG-80H-48 has no adjustment or dimming and is IP67. The -48A adds output voltage/current adjustment via potentiometers (IP65). The -48AB adds output current adjustment and 3-in-1 dimming (IP65). The -48B adds the dimming input only and retains IP67.

Is the HLG-80H-48A protected enough for a semi-outdoor installation under an awning?

Yes. Its IP65-rated metal housing is designed for indoor and outdoor applications, which suits covered outdoor areas like awnings, pergolas, and covered walkways. For fully exposed rain installations, consider the IP67-rated HLG-80H-48 base model.
