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-24 to power a large 24V LED strip installation outdoors?

Yes. The HLG-320H-24 outputs 24V at up to 13.34A (320W), and its IP65/IP67-rated metal housing is designed for indoor and outdoor applications, making it suitable for long 24V LED strip runs outdoors. Its -40°C to +90°C case-temperature (Tcase) range handles harsh weather, with derating at high temperature.

Is the HLG-320H-24 suitable for powering 24V LED signage or channel letters?

Yes. At 320W and 24V it can drive a substantial array of 24V LED sign modules or channel letters. The wide 90-305VAC input and IP65/IP67 rating make it a reliable choice for outdoor commercial signage exposed to varying mains voltages and weather.

Can the HLG-320H-24 drive 24V LED high-bay or warehouse lighting?

Yes. With 320W at 24V and constant-current operation, the HLG-320H-24 can power high-bay 24V LED fixtures in warehouses, factories, or large indoor spaces. Its IP65/IP67 rating also makes it suitable for damp or dusty industrial environments.

How many meters of 24V LED strip can the HLG-320H-24 handle?

Divide 320W by your strip's power consumption per meter. For instance, a strip rated at 14.4W/m would allow about 22.2 meters (320W / 14.4W per meter). Always check your strip's rated power per meter and keep the total load at or below 320W.

Can the HLG-320H-24 be installed in a location subject to temporary flooding or standing water?

The HLG-320H series is rated IP65 or IP67 depending on type, but the datasheet does not specify immersion depth or flooding performance. Check the rating of your type and the IP installation cautions in MEAN WELL's user manual before installing it where flooding or standing water may occur.
