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-36B for dimmable 36V LED parking lot or street lighting?

Yes. The HLG-320H-36B provides 320W at 36V with dimming capability, and the series' IP65/IP67-rated metal housing is designed for outdoor applications, making it well suited for parking lot and street light fixtures. Dimming allows reduced output during low-traffic hours for energy savings.

Is the HLG-320H-36B a good fit for outdoor 36V LED flood lighting with dimming control?

It is an excellent choice for dimmable flood lighting. The 320W output can power large 36V LED flood fixtures, the dimming input supports 1-10V, PWM, and resistance signals for flexible control, and the IP65/IP67-rated metal housing suits outdoor mounting.

Can I power 36V dimmable LED tunnel or underpass lighting with the HLG-320H-36B?

Yes. At 320W and 36V with an IP65/IP67-rated metal housing and a -40°C to +90°C case-temperature (Tcase) range, the HLG-320H-36B suits the conditions found in tunnels and underpasses. The dimming function lets you adjust brightness based on ambient light or traffic conditions.

How many meters of 36V LED strip can the HLG-320H-36B support?

The HLG-320H-36B supplies 320W at 36V. Divide 320W by your strip's wattage per meter. For instance, a strip rated at 16W/m would allow up to 20 meters (320W / 16W per meter = 20m). Always check your strip's rated power per meter and keep the total load within 320W.

Can the HLG-320H-36B withstand submersion or heavy rain exposure?

The HLG-320H series is rated IP65 or IP67 depending on type, and its metal housing is designed for indoor and outdoor applications, but the datasheet does not state a submersion depth. Check the B-type's rating and the IP installation cautions in MEAN WELL's user manual before installing it where heavy rain, flooding, or submersion may occur.

How does the HLG-320H-36B compare to the HLG-320H-36 and HLG-320H-36AB?

All three deliver 320W at 36V and 8.9A. The base HLG-320H-36 has fixed output. The -36AB combines output current adjustment and 3-in-1 dimming. The -36B (this model) provides dimming without potentiometers. The series is rated IP65 or IP67 depending on type, so check each type's rating for fully exposed installations.
