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-15A to fine-tune the drive level for 15V LED high-bay fixtures?

Yes. The HLG-320H-15A includes built-in potentiometers that let you adjust output voltage (13.5-17V) and current (9.5-19A). This is useful when your 15V high-bay fixtures perform better at a slightly reduced drive level, or when you need to match the driver output to the LED module within the 7.5-15V CC range.

Is the HLG-320H-15A suitable for powering 15V LED sign modules in a covered outdoor display?

Yes. At 285W and 15V, with the series' IP65/IP67-rated metal housing designed for indoor and outdoor use, the HLG-320H-15A suits covered outdoor sign cabinets, canopy-mounted signage, or partially sheltered display cases. The adjustable output lets you optimize brightness for the specific sign layout.

Can the HLG-320H-15A drive a series string of 15V LED COB arrays in a studio lighting setup?

Yes. The HLG-320H-15A provides up to 19A at 15V in constant-current mode, suitable for COB LED arrays used in studio or photography lighting. The built-in potentiometer allows precise current trimming to match the COB manufacturer's recommended operating point.

How many watts of 15V LED load can the HLG-320H-15A handle?

The HLG-320H-15A delivers up to 285W at 15V (19A). Your combined LED load must stay at or below 285W. For example, six 15V LED panels rated at 45W each would total 270W, comfortably within the driver's capacity. Always verify each panel's rated wattage before connecting.

Is the HLG-320H-15A suitable for a dusty warehouse environment?

Yes. The HLG-320H series is rated IP65 or IP67 depending on type, and its metal housing is designed for indoor and outdoor applications. This makes it appropriate for warehouses, workshops, and light-industrial spaces where airborne particles are common. For standing water or submersion risk, check the A-type's rating and MEAN WELL's IP installation cautions.
