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-C2800B to power dimmable LED high-bay fixtures?

Yes. The HLG-320H-C2800B provides 319.2W at 2800mA constant current with a built-in dimming interface (0-10VDC, 10V PWM, or resistance). It can drive high-bay LED modules whose string voltage falls within the 57-114V range, and the dimming capability supports occupancy-based or scheduled brightness reduction.

Is the HLG-320H-C2800B suitable for LED street lighting with photocell dimming?

Yes. The dimming input accepts 0-10VDC, 10V PWM, or resistance, which many photocell dimming controllers can provide. At 319.2W and 2800mA, it can power street light modules in the 57-114V range. The series is IP65 or IP67 approved against dust and water, though it should be mounted in a pole-top enclosure for best protection.

Can the HLG-320H-C2800B drive LED fixtures in a cold-storage facility?

Yes. Its case temperature (Tcase) range of -40°C to +85°C covers cold-storage and freezer environments. The 2800mA constant current output at up to 319.2W can drive high-output LED luminaires, and the dimming input allows reducing light during non-working hours to save energy.

Will the HLG-320H-C2800B work for illuminated LED advertising displays?

Yes, provided the display modules operate within the 57-114V CC voltage range at 2800mA. The built-in dimming input is useful for reducing brightness at night. At 319.2W total output, it can handle large illuminated sign panels or backlit display cabinets.

How does the HLG-320H-C2800B differ from the HLG-320H-C2800A?

Both share identical core specs: 319.2W, 118V, 2800mA, and a 57-114V CC range. The -B model includes a dimming input (0-10VDC/PWM/resistance) but no output adjustment potentiometer. The -A model has an output adjustment potentiometer (1400-2800mA) but no dimming input. Choose -B for external dimming control or -A for fixed output trimming.

Can the HLG-320H-C2800B be mounted in an outdoor junction box?

Yes. The HLG-320H-C series is IP65 or IP67 approved for dust and water protection, making it suitable for outdoor junction boxes, electrical cabinets, or covered mounting locations. For submerged or heavily flooded installations, confirm this version's IP rating first.
