Test conditions and notes13

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.

FAQ

Can I use the HLG-320H-30B for outdoor 30V LED strip installations that need dimming?

Yes. The HLG-320H-30B delivers 320W at 30V with dimming capability, and the series' IP65/IP67-rated metal housing is designed for outdoor applications. It supports 1-10V, PWM, and resistance dimming signals for smooth brightness control.

Is the HLG-320H-30B a good choice for dimmable 30V LED facade or building lighting?

It is well suited for architectural facade lighting where dimming and weather resistance are both essential. The 320W capacity can drive extensive 30V LED arrays, and the IP65/IP67-rated metal housing is designed for both indoor and outdoor mounting.

Can I power a 30V dimmable LED sign with the HLG-320H-30B?

Yes, provided total power draw stays within 320W. The dimming function lets you reduce brightness for nighttime or ambient conditions, and the IP65/IP67 rating means the driver can be mounted inside or outside the sign cabinet. The wide 90-305VAC input handles different mains voltages globally.

Can the HLG-320H-30B be installed in a wet or underground location?

The HLG-320H series is rated IP65 or IP67 depending on type, with a metal housing designed for indoor and outdoor applications and a -40°C to +90°C case-temperature (Tcase) range. The datasheet does not state a submersion depth, so check the B-type's rating and MEAN WELL's IP installation cautions before using it in underground vaults or other wet locations.

How many meters of 30V LED strip can the HLG-320H-30B drive?

The HLG-320H-30B provides 320W at 30V. Divide 320W by your strip's rated wattage per meter. For example, a strip drawing 20W/m would support up to 16 meters (320W / 20W per meter = 16m). Always check your strip's rated power per meter and keep total load at or below 320W.

How does the HLG-320H-30B differ from the HLG-320H-30 and HLG-320H-30A?

All three deliver 320W at 30V and 10.7A. The base HLG-320H-30 has fixed output. The -30A adds output voltage and current adjustment via potentiometers. The -30B (this model) adds 3-in-1 dimming but does not include potentiometers. The series is rated IP65 or IP67 depending on type.
