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-48AB to power dimmable 48V LED strip installations?
Yes. The HLG-320H-48AB delivers 48V at up to 6.7A (320W) and accepts 1-10V or PWM dimming signals. This makes it ideal for 48V LED strip installations where you need external brightness control, such as architectural accent lighting or daylight-responsive systems.
Is the HLG-320H-48AB suitable for smart building 48V LED lighting with automated dimming?
Yes. The AB suffix means this model has both output current adjustment via potentiometer and a 1-10V/PWM/resistance dimming input. You can integrate it with building management systems, occupancy sensors, or daylight harvesters that provide these signals for automated brightness control at up to 320W.
Can the HLG-320H-48AB drive 48V LED fixtures in a retail display setting?
Yes. At 320W and 48V, it can power extended runs of retail display lighting. The dimming input allows scene-setting for different merchandise presentations, and the current potentiometer lets you set the output current (3.35-6.7A) to match the fixture requirements for uniform brightness.
Can I use the HLG-320H-48AB for 48V horticultural LED panels with light-schedule control?
Yes. The 320W output handles high-power grow panels at 48V, and the dimming input can be driven by a grow-light controller to adjust intensity for different growth stages. The current potentiometer also lets you set the output current to the panel's operating point.
How many meters of 48V LED strip can the HLG-320H-48AB power?
Divide 320W by your strip's rated power per meter. For example, a strip rated at 12W/m would allow about 26.6 meters (320W / 12W per meter). Always check your strip's rated power per meter and keep the total load at or below 320W for reliable operation.
Is the HLG-320H-48AB weatherproof enough for a covered outdoor patio installation?
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 patios, pergolas, or soffit-mounted applications. Check the AB-type's rating before a fully rain-exposed installation.
