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-24AB with a building automation system to dim 24V LED lighting?

Yes. The HLG-320H-24AB accepts 1-10V, PWM and resistance dimming signals, making it compatible with building management and automation systems that provide them. At 320W and 24V with a current-adjust potentiometer, you get both automated and manual brightness control for large 24V LED installations.

Is the HLG-320H-24AB a good choice for dimmable 24V LED cove or indirect lighting?

Yes. With 320W at 24V, built-in dimming, and adjustable output, it is well suited for architectural cove lighting where smooth brightness transitions and precise output tuning are important. The dimming input allows integration with scene controllers or timers.

Can the HLG-320H-24AB power a large 24V LED strip installation with scheduled dimming?

Yes. The 1-10V/PWM dimming input lets you pair with a timer or daylight sensor to reduce brightness automatically, for example dimming retail display lighting after business hours. At 320W and 24V, it supports long continuous strip runs.

How many meters of 24V LED strip can the HLG-320H-24AB drive?

The HLG-320H-24AB supplies up to 320W. Divide 320 by your strip's wattage per meter to get the maximum run length. A strip rated at 16W/m, for instance, allows up to 20 meters (320W / 16W per meter = 20m). Always check your strip's rated power per meter before sizing.

Is the HLG-320H-24AB suitable for a damp indoor environment like a commercial kitchen or wash-down area?

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 commercial kitchens where splashing occurs. The datasheet does not rate it for wash-down or submersion, so check the AB-type's rating and MEAN WELL's IP installation cautions for those areas.

What is the input voltage range of the HLG-320H-24AB for international installations?

The HLG-320H-24AB accepts 90-305VAC input, covering virtually all global mains voltages from 100V (Japan) to 277V (US commercial). This wide range eliminates the need for an external step-down transformer in most international installations.
