Test conditions and notes13

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.

FAQ

Can I use the HLG-480H-30B for a large outdoor 30V LED installation with dimming in a fully exposed location?

Yes. The HLG-480H-30B delivers 480W at 30V (16A) with a 3-in-1 dimming input (0-10VDC, 10V PWM or resistance) and IP67 waterproof rating. It can be mounted in locations directly exposed to rain, snow, or temporary water pooling, making it ideal for building facade lighting, bridge illumination, or outdoor signage with dimming control.

Is the HLG-480H-30B suitable for 30V LED fixtures in a car wash or marine dock?

Yes. The IP67 waterproof rating protects against temporary immersion up to 1 meter, and the metal housing is fanless and fully enclosed. Its case temperature (Tcase) range of -40°C to +90°C covers wide temperature swings, with output derating needed above about 60°C ambient at rated current. At 480W it can power substantial 30V LED fixture loads.

Can the HLG-480H-30B power dimmable 30V LED tunnel or underpass lighting?

Yes. Tunnel and underpass lighting benefits from dimming to adjust brightness between day and night conditions, and the HLG-480H-30B provides a 0-10V/PWM/resistance dimming input for that purpose. Its 480W output handles high-wattage tunnel fixture arrays, and the IP67 rating withstands the moisture and dust typical in those environments.

How many meters of 30V LED strip can the HLG-480H-30B drive?

Divide 480W by your strip's rated wattage per meter. A strip rated at 8W/m could run up to 60 meters (480W / 8W per meter = 60m). A higher-density strip at 18W/m would allow about 26 meters. Check your strip's rated power per meter and ensure total consumption stays at or below 480W.

How does the HLG-480H-30B handle freezing conditions and water exposure?

The HLG-480H-30B is rated for a case temperature (Tcase) down to -40°C, so it handles deep-freeze conditions without issue. The IP67 rating means it can withstand temporary immersion in up to 1 meter of water for 30 minutes, though not permanent submersion. This makes it suitable for cold-climate outdoor installations exposed to rain, snow, or brief water pooling.
