Test conditions and notes14

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. BIS certification is for HLG-320H-A only, but products sourced from Taiwan do not have the BIS logo, please contact your MEAN WELL sales for more information.
14. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

Can I use the HLG-320H-48 to power 48V LED strip lighting outdoors?

Yes. The HLG-320H-48 outputs 48V at up to 6.7A (320W), and its IP65/IP67-rated metal housing is designed for indoor and outdoor applications, making it suitable for outdoor 48V LED strip installations. Its -40°C to +90°C case-temperature (Tcase) range handles harsh weather, with derating at high temperature.

Is the HLG-320H-48 suitable for powering 48V LED high-bay warehouse lighting?

Yes. At 320W it can drive one or more 48V high-bay LED fixtures. The constant-current mode with a CC voltage range of 24-48V accommodates slight voltage differences between fixtures. Its wide 90-305VAC input works with most industrial power supplies.

Can I use the HLG-320H-48 for 48V commercial LED signage?

Yes. With 320W at 48V, the HLG-320H-48 can drive large 48V LED sign modules, channel letters, or light boxes. The IP65/IP67-rated metal housing is designed for outdoor mounting, and the series has a typical life expectancy above 62,000 hours at Tcase of about 75°C.

How many meters of 48V LED strip can the HLG-320H-48 power?

Divide 320W by your strip's rated power per meter. For example, a 48V strip rated at 10W/m would allow up to 32 meters (320W / 10W per meter = 32m). Always check your strip's rated power per meter and keep total load at or below 320W.

Can the HLG-320H-48 be mounted in a below-grade vault or wet-location junction box?

The HLG-320H series is rated IP65 or IP67 depending on type, and its metal housing is designed for indoor and outdoor applications, but the datasheet does not state a submersion depth. Check the rating of your type and the IP installation cautions in MEAN WELL's user manual before installing it in below-grade vaults or wet-location junction boxes.

Does the HLG-320H-48 operate reliably in extreme cold or hot environments?

Yes. Its case temperature (Tcase) range is -40°C to +90°C, covering extreme winter cold, with output derating at high temperatures per the load vs temperature curve. The fanless metal housing is cooled by free-air convection, which matters in enclosed or rooftop installations during summer.
