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-C1400A to drive high-power LED floodlights for sports facilities?

Yes. The HLG-320H-C1400A delivers 1400mA constant current at up to 320.6W with a CC voltage range of 114-229V. This higher current rating makes it suitable for high-power floodlight fixtures in stadiums, sports courts, or large outdoor event spaces that use series LED strings within that voltage range.

Is the HLG-320H-C1400A a good choice for driving LED grow lights that need 1400mA?

Yes, provided your grow light panel is designed for 1400mA constant-current drive with a total forward voltage between 114V and 229V. The 320.6W capacity handles demanding horticultural LED arrays. The built-in potentiometer lets you trim the output to fine-tune light intensity for different crop stages.

Can I adjust the output current of the HLG-320H-C1400A?

Yes. The A suffix indicates a built-in potentiometer for output adjustment. This allows you to trim the constant-current drive level between 700mA and 1400mA to match your specific LED load without needing external control equipment. The CC voltage range operates between 114V and 229V at up to 1400mA.

Is the HLG-320H-C1400A suitable for large-format LED panel lighting in commercial buildings?

Yes. At 320.6W and 1400mA, this driver handles high-power commercial LED panels with series strings in the 114-229V range. The adjustable output lets installers match the driver precisely to the panel's optimal drive point. The IP65/IP67-approved enclosure and wide 90-305VAC input suit most commercial building environments.

What LED string voltage should I target when using the HLG-320H-C1400A?

Your series LED string's total forward voltage must fall within 114-229V. The driver regulates at 1400mA constant current across this range. The number of LEDs in series depends on each LED's forward voltage — add them up and confirm the total is within the 114-229V window.

Can I mount the HLG-320H-C1400A in a dusty industrial environment?

Yes. The HLG-320H-C series is IP65 or IP67 approved, so the enclosure is dust-tight and protected against water. This makes it suitable for factories, workshops, or equipment rooms where airborne dust and occasional moisture are present. Keep the case at or below its +85°C maximum case temperature (Tcase) in warm environments.
