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-48B to power 48V LED strip lighting outdoors with dimming?

Yes. The HLG-480H-48B outputs 48V at up to 10A (480W) and includes a 3-in-1 dimming input (0-10VDC, 10V PWM or resistance) for brightness control. Its IP67 waterproof rating allows mounting in fully exposed outdoor locations, including direct rain exposure.

Is the HLG-480H-48B a good choice for large outdoor 48V LED signage?

Yes. With 480W at 48V and IP67 waterproofing, this driver is designed for exposed outdoor installations. The dimming input lets you reduce sign brightness at night to save energy or meet local ordinances, using an external 0-10VDC, 10V PWM or resistance dimming signal.

Can the HLG-480H-48B power 48V LED fixtures on a building facade?

Yes. Its 480W capacity and IP67 waterproof rating make it suitable for facade wash lights, cove lighting, or architectural accent lighting that uses 48V LED fixtures. The dimming input supports scene control or daylight-responsive dimming through an external controller.

How many meters of 48V LED strip can the HLG-480H-48B drive?

That depends on the strip's rated power per meter. The HLG-480H-48B supplies up to 480W at 48V. For a strip rated at 15W/m, you could run up to 32 meters (480W / 15W per meter = 32m). Always check your strip's rated power per meter and keep the total load at or below 480W.

Can the HLG-480H-48B handle extreme outdoor temperatures?

Yes, within its derating limits. The HLG-480H-48B is rated for a case temperature (Tcase) of -40°C to +90°C, suiting freezing climates; at rated current in constant-current mode the maximum ambient is about 60°C (230VAC), so plan derating for hot rooftop installations. Combined with its IP67 waterproof rating, it can withstand rain, snow, and dust without a secondary enclosure.
