Certifications & ratings

Type: HL

Test conditions and notes11

1. All parameters NOT specially mentioned are measured at 230VAC input, rated current and 25℃ of ambient temperature.
2. Please refer to "DRIVING METHODS OF LED MODULE".
3. De-rating may be needed under low input voltages. Please refer to “STATIC CHARACTERISTIC” sections for details.
4. 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.
5. 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)
6. 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.
7. 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.
8. Please refer to the warranty statement on MEAN WELL's website at http://www.meanwell.com
9. 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).
10. 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
11. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

Can I use the HLG-320H-C2800AB for dimmable warehouse LED high-bay lighting?

Yes. The HLG-320H-C2800AB delivers 319.2W at 2800mA with both adjustable output and dimming input (0-10VDC, 10V PWM, or resistance). This combination lets you set a baseline output level with the potentiometer and then dynamically dim via an external signal, which is ideal for warehouse occupancy- or daylight-based dimming.

Is the HLG-320H-C2800AB a good choice for sports field LED floodlights with dimming?

It can power high-output floodlight modules operating within its 57-114V CC range at 2800mA. The dimming input allows reducing output for practice sessions versus competition lighting. However, the series is IP65 or IP67 approved depending on version, so confirm this model's rating and mount it in a sheltered enclosure if directly exposed to heavy rain.

Can I use the HLG-320H-C2800AB for large-format LED signage that needs brightness control?

Yes. At 319.2W and 2800mA, it has enough power for large sign modules in the 57-114V range. The built-in dimming lets you reduce brightness at night to comply with local light-pollution regulations or save energy, while the adjustable output trims the baseline to match your exact module configuration.

What is the difference between the A, AB, B, and DA variants of the HLG-320H-C2800?

All four share the same 319.2W / 118V / 2800mA core specs with a 57-114V CC range. The -A has an adjustable potentiometer only (1400-2800mA). The -AB adds both adjustment and 3-in-1 dimming (0-10VDC, 10V PWM, or resistance). The -B provides dimming only. The -DA replaces analog dimming with a DALI digital interface. The series is IP65 or IP67 approved depending on version.

How many LEDs can the HLG-320H-C2800AB drive in series?

The number depends on each LED's forward voltage. With a CC voltage range of 57-114V at 2800mA, divide your desired string voltage by the individual LED forward voltage. Ensure the total string voltage remains within 57-114V for proper constant current regulation.

Is the HLG-320H-C2800AB rated for dusty industrial environments?

Yes. The HLG-320H-C series is IP65 or IP67 approved; both ratings mean the enclosure is dust-tight (no dust ingress) and protected against water. This makes it suitable for factories, workshops, and dusty processing areas. The -40°C to +85°C case temperature (Tcase) range also covers harsh thermal conditions.
