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-36AB with a 0-10V dimmer for 36V LED retail display lighting?

The HLG-320H-36AB supports dimming via 1-10VDC, 10V PWM, and resistance signals, so use a dimmer or controller that works in the 1-10V range. Combined with 320W at 36V and output current adjustment, it is a strong choice for retail environments where scene-based brightness control is needed.

Is the HLG-320H-36AB suitable for dimmable 36V LED stage or studio lighting?

It works well for stage and studio lighting where smooth dimming and precise current control are critical. The built-in potentiometer sets the baseline output current (4.45-8.9A), while the dimming input allows real-time brightness adjustments during performances or shoots.

Can I power a dimmable 36V LED light panel array with the HLG-320H-36AB?

Yes, as long as the total load does not exceed 320W. The HLG-320H-36AB delivers 36V at up to 8.9A with both adjustable output and dimming, letting you fine-tune base brightness and provide dynamic dimming control for panel arrays in commercial or architectural settings.

How many meters of 36V LED strip can the HLG-320H-36AB drive?

Divide 320W by your strip's rated power per meter. A strip drawing 12W/m could run approximately 26.6 meters (320W / 12W per meter). A higher-power strip at 20W/m would allow about 16 meters. Always check your strip's rated power per meter and keep total load at or below 320W.

Can the HLG-320H-36AB be used in an outdoor covered patio or pergola?

Yes. The HLG-320H series is rated IP65 or IP67 depending on type, and its metal housing is designed for indoor and outdoor applications, which suits covered outdoor areas where the driver is shielded from direct rain and standing water. For fully exposed locations, check the AB-type's rating first.

What does the 'AB' suffix mean on the HLG-320H-36AB compared to the other 36V variants?

The 'AB' suffix indicates the model combines output current adjustment (potentiometer) and dimming capability. The base HLG-320H-36 has fixed output. The -36A has output voltage and current adjustment only. The -36B has dimming only. The -36AB (this model) offers both current adjustment and dimming. The series is rated IP65 or IP67 depending on type.
