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-15AB to power dimmable 15V LED retail display lighting?

Yes. The HLG-320H-15AB provides 285W at 15V with both a built-in potentiometer for output current adjustment (9.5-19A) and a dimming input that accepts 1-10V, PWM, or resistance signals. This combination is ideal for retail environments where you need both precise output tuning and dynamic brightness control throughout the day.

Is the HLG-320H-15AB a good choice for 15V LED task lighting in an office with a lighting control system?

Yes. The dimming input on the HLG-320H-15AB accepts 1-10VDC, 10V PWM or resistance, so it integrates with building automation controllers that provide these signals, allowing the lighting system to adjust brightness on schedule or by occupancy sensor. The potentiometer lets you set the output current to match the fixture requirements.

Can the HLG-320H-15AB be used for 15V LED accent lighting in a hospitality setting?

Yes. At 285W and 15V, it has enough capacity for extensive accent lighting runs. The dimming input allows integration with scene controllers for different ambiance settings, while the adjustable output ensures the driver matches the LED modules' ideal operating point.

How much 15V LED strip can the HLG-320H-15AB power?

The HLG-320H-15AB provides up to 285W at 15V. Divide 285W by your strip's rated wattage per meter to estimate the maximum run length. For example, a 15V strip rated at 12W/m would allow 285 / 12 = approximately 23.7 meters. Always check your strip's rated power per meter and stay within 285W total.

Can the HLG-320H-15AB be mounted in a semi-exposed outdoor location like under an awning?

Yes. The HLG-320H series is rated IP65 or IP67 depending on type, and its metal housing is designed for indoor and outdoor applications, making it appropriate for covered or semi-sheltered outdoor installations such as awnings, canopies, and building soffits. Where submersion or heavy pooling water may occur, check the AB-type's rating and MEAN WELL's IP installation cautions.
