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-15 to power 15V LED modules in an outdoor billboard?

Yes. The HLG-320H-15 delivers 285W at 15V with up to 19A, providing ample current for multiple 15V LED modules in a billboard or large-format sign. The series' IP65/IP67-rated metal housing is designed for both indoor and outdoor applications, including signs subject to rain, dust, and temperature swings.

Is the HLG-320H-15 suitable for driving 15V LED grow-light panels?

Yes, provided the grow-light panels operate at 15V and the total load does not exceed 285W. The constant-current mode with a CC range of 7.5-15V accommodates LED panels whose forward voltage may shift with temperature during extended grow cycles.

Can I use the HLG-320H-15 for 15V LED floodlighting on a building exterior?

Yes. With 285W at 15V and an IP65/IP67-rated metal housing, the HLG-320H-15 is well suited for outdoor floodlight installations. It handles wide input voltages from 90-305VAC, accommodating various mains supplies found in commercial and industrial sites worldwide.

How much 15V LED load can the HLG-320H-15 support?

The HLG-320H-15 supplies up to 285W at 15V (19A). Your total connected LED load must not exceed 285W. For example, if you have 15V LED modules rated at 50W each, you could power up to five modules (250W total) with comfortable headroom. Always verify each module's rated wattage.

Can the HLG-320H-15 be installed in a fully exposed rooftop location?

The HLG-320H series is rated IP65 or IP67 depending on type and is designed for outdoor applications, with a case-temperature (Tcase) range of -40°C to +90°C (output derates at high temperature). Check the rating of your type and the IP installation cautions in MEAN WELL's user manual before a fully exposed rooftop installation.

What are the differences between the HLG-320H-15, 15A, 15AB, and 15B models?

All four models share the same 285W / 15V / 19A core output. The base HLG-320H-15 has fixed output with no adjustment or dimming. The -15A adds built-in potentiometers for voltage and current trimming. The -15AB adds a current potentiometer plus a 3-in-1 dimming input (1-10VDC, 10V PWM or resistance). The -15B has the dimming input only. The series is rated IP65 or IP67 depending on type.
