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-36A for 36V LED strip lighting where I need to fine-tune brightness?

Yes. The HLG-320H-36A features built-in potentiometers that let you adjust the output voltage (32-39V) and current (4.45-8.9A). This is useful for optimizing brightness and efficiency when the LED strip does not need exactly 36V or the full 8.9A.

Is the HLG-320H-36A suitable for powering 36V LED architectural or landscape lighting?

It works well for architectural and landscape lighting where the load needs to be tuned. The adjustable output accommodates slight voltage variations across different LED fixtures, and 320W is sufficient for substantial lighting runs. Check the A-type's IP rating (the series is IP65 or IP67 depending on type) when choosing a mounting location.

Can I use the HLG-320H-36A for a 36V LED grow light setup?

Yes, provided total power draw is within 320W. The adjustable output lets you set the precise current (4.45-8.9A) for your grow light panels. Its wide 90-305VAC input handles different electrical supplies, and the 18-36V constant-current range accommodates various 36V LED grow light configurations.

How many meters of 36V LED strip can the HLG-320H-36A handle?

The HLG-320H-36A delivers up to 320W at 36V. Divide 320W by your strip's rated wattage per meter. For example, a strip at 18W/m would support roughly 17.7 meters (320W / 18W per meter). Always verify your strip's rated power per meter and stay within the 320W limit.

Is the HLG-320H-36A suitable for an exposed outdoor installation?

The HLG-320H series is rated IP65 or IP67 depending on type, and its metal housing is designed for indoor and outdoor applications. Before a fully exposed installation, confirm the A-type's IP rating and follow the IP installation cautions in MEAN WELL's user manual.

What does the 'A' suffix mean on the HLG-320H-36A versus the base HLG-320H-36?

The 'A' suffix indicates the model includes built-in potentiometers for adjusting output voltage (32-39V) and current (4.45-8.9A). The base HLG-320H-36 has fixed output. Both share the same 320W, 36V, 8.9A output at default settings.
