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-C1050A to power high-output LED floodlights?

Yes. The HLG-320H-C1050A delivers 1050mA constant current at up to 320.25W with a CC voltage range of 152-305V. This makes it well suited for high-output LED floodlights used in sports facility lighting, parking lot illumination, or building facade wash lights that require high-voltage series-connected LED arrays.

Is the HLG-320H-C1050A suitable for driving LEDs in large-format commercial signage?

Yes. At 320.25W and 1050mA constant current, this driver can power high-voltage LED strings in large channel letters, pylon signs, or monument sign cabinets. The built-in potentiometer lets you trim the output current between 525mA and 1050mA to suit your LED string within the 152-305V range.

Can I adjust the output of the HLG-320H-C1050A to match my LED load?

Yes. The A suffix indicates a built-in output adjustment potentiometer. This lets you fine-tune the constant-current output level to match your specific LED configuration without needing an external dimmer or controller. The CC voltage range spans 152-305V.

Is the HLG-320H-C1050A appropriate for high-bay LED lighting in industrial facilities?

Yes. With 320.25W at 1050mA, it handles high-bay fixtures with series LED strings in the 152-305V range. The IP65/IP67-approved enclosure and -40°C to +85°C case temperature (Tcase) range suit factories, distribution centers, and covered industrial bays where dust and occasional moisture are present.

What total forward voltage range should my LED string have for the HLG-320H-C1050A?

Your series-connected LED string's total forward voltage should fall within 152-305V. The driver operates in constant-current mode at 1050mA. The exact number of LEDs you can wire in series depends on each LED's individual forward voltage — sum them to ensure the total stays in the 152-305V window.

Can I install the HLG-320H-C1050A outdoors under a canopy or in a ventilated cabinet?

Yes. The HLG-320H-C series is IP65 or IP67 approved, protecting against dust ingress and water, making it suitable for covered outdoor locations such as canopy-mounted fixtures, ventilated electrical cabinets, or sheltered pole-mount enclosures. Avoid fully submerged installations.
