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-42A with its adjustable output to fine-tune 42V LED strip brightness?

Yes. The A suffix means it has a built-in potentiometer for adjusting output voltage (35.7-44.1V) and current (5.7-11.4A). You can trim the output to match your 42V LED strip's optimal drive level. This is useful when you want to slightly reduce brightness or match a specific LED forward voltage without an external dimmer.

Is the HLG-480H-42A a good choice for powering adjustable 42V LED high-bay lights?

Yes. At 478.8W and 42V, it has the capacity for high-bay LED fixtures. The adjustable output lets you set the exact voltage and current to match your fixtures' requirements, which can extend LED lifespan and reduce energy consumption by avoiding over-driving.

Can I use the HLG-480H-42A for 42V commercial LED display lighting?

Yes. With 478.8W at 42V and 11.4A, it can power retail display cabinets, museum lighting, or gallery track systems that use 42V LEDs. The adjustable output is especially useful in these settings where precise light levels matter. Its wide 90-305VAC input works with most commercial power infrastructure globally.

How many meters of 42V LED strip can the HLG-480H-42A support?

Divide the 478.8W rated power by the strip's power draw per meter. For instance, a 42V strip consuming 12W/m could be run up to about 39.9 meters (478.8W / 12W per meter = 39.9m). Always verify your strip's rated power per meter and ensure total load stays at or below 478.8W.

Is the HLG-480H-42A suitable for damp or semi-outdoor installations?

Yes. Its IP65 water-resistant rating protects against low-pressure water jets and dust ingress, making it suitable for covered patios, parking garages, food-processing areas, or any location with splashing water. For fully exposed rain or submersion, consider the IP67-rated HLG-480H-42 or HLG-480H-42B instead.
