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-42 for a large 42V LED lighting installation?
Yes. The HLG-480H-42 outputs 478.8W at 42V and up to 11.4A, making it suitable for powering long runs of 42V LED strips, multiple 42V LED panel lights, or high-power 42V LED arrays. Its constant-current mode with a CC range of 21-42V helps maintain stable output across varying LED loads.
Is the HLG-480H-42 appropriate for powering 42V LED grow lights?
Yes. With 478.8W at 42V, it provides ample power for high-output LED grow light panels that operate at 42V. The wide 90-305VAC input handles different facility power supplies, and the IP67 waterproof rating protects against humidity common in greenhouse or indoor growing environments.
Can the HLG-480H-42 drive 42V LED modules for large outdoor signage?
Yes. At 478.8W and 42V, it can power substantial outdoor sign arrays. The IP67 waterproof rating means it can be mounted in exposed outdoor locations without additional weatherproofing. Note that this base model has a fixed output with no dimming or adjustment capability.
How many meters of 42V LED strip can the HLG-480H-42 handle?
Divide the 478.8W rated power by your strip's rated power per meter. For example, a 42V strip rated at 15W/m could be run up to about 31.9 meters (478.8W / 15W per meter = 31.9m). Check your strip's rated power per meter and keep total load at or below 478.8W for reliable operation.
Can the HLG-480H-42 be mounted outdoors in direct rain and freezing temperatures?
Yes. Its IP67 waterproof rating protects against temporary immersion up to 1 meter, so direct rain is not a concern. The case temperature (Tcase) range of -40°C to +90°C covers deep-freeze winters, and in hot summers output derating applies above about 60°C ambient at rated current, making it suitable for fully exposed outdoor installations.
