Test conditions and notes12

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

FAQ

Can I use the HLG-480H-54 to power long runs of 54V LED strip lighting?

Yes. The HLG-480H-54 delivers 480W at 54V with up to 8.9A of output current. The higher 54V rail reduces voltage drop over long cable runs compared to lower-voltage drivers, making it a strong choice for extended commercial LED strip installations.

Is the HLG-480H-54 suitable for powering 54V LED high-bay fixtures in a warehouse?

Yes. At 480W, this driver can supply substantial power to 54V high-bay LED luminaires. The constant-current operation with a CC voltage range of 27-54V provides stable output even with slight variations in fixture forward voltage across the string.

Can the HLG-480H-54 drive large 54V LED panel arrays for commercial signage?

Yes. The 480W output capacity can power sizable 54V LED panel configurations used in sign cabinets or backlit displays. Its IP67 waterproof rating makes it suitable for outdoor sign installations without needing a separate weatherproof enclosure.

How many meters of 54V LED strip can the HLG-480H-54 support?

That depends on your strip's rated power per meter. The HLG-480H-54 provides up to 480W at 54V. For example, a strip rated at 12W/m would allow up to 40 meters (480W / 12W per meter = 40m). Always check your strip's rated power per meter and keep total load at or below 480W.

Can the HLG-480H-54 be installed outdoors in exposed weather conditions?

Yes. The HLG-480H-54 carries an IP67 waterproof rating, meaning it can withstand temporary immersion and direct rain. Its case temperature (Tcase) range of -40°C to +90°C handles extreme cold, and on hot rooftops output derating applies above about 60°C ambient at rated current, all without a secondary enclosure.
