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-C1750A to power high-output LED grow light modules?

Yes, provided the LED modules operate at 1750mA and their total string voltage falls within the 91-183V constant-current range. The 320.25W output is well suited for high-intensity horticulture fixtures. The built-in potentiometer on the -A variant lets you fine-tune the output current to match specific LED bin characteristics.

Is the HLG-320H-C1750A a good fit for driving LED high-bay fixtures in an industrial facility?

Yes. At 1750mA and up to 320.25W, it can power high-bay LED modules with string voltages in the 91-183V range. The adjustable output (875-1750mA) lets you reduce current to extend LED lifespan or match specific fixture requirements. Its -40°C to +85°C case temperature (Tcase) range and IP65/IP67-approved enclosure handle typical factory conditions.

Can the HLG-320H-C1750A drive LED modules in outdoor area lighting?

Yes, in sheltered outdoor locations. The HLG-320H-C series is IP65 or IP67 approved against dust and water, suitable for installation under canopies, inside poles, or in ventilated enclosures. For fully exposed outdoor mounting, confirm this version's IP rating first.

What does the adjustable output on the HLG-320H-C1750A allow me to do?

The built-in potentiometer lets you adjust the output current between 875mA and the rated 1750mA. This is useful for derating the LED drive current to reduce heat, extend LED life, or match a specific LED module's optimal operating current without needing an external dimmer or controller.

How many series LEDs can the HLG-320H-C1750A support?

The number depends on each LED's forward voltage at 1750mA. The driver's constant-current output range is 91-183V, so you divide that range by the individual LED forward voltage to determine the allowable series count. Ensure the total string voltage under operating conditions stays within 91-183V.

Can the HLG-320H-C1750A operate in freezing environments like a cold storage facility?

Yes. The HLG-320H-C1750A is rated for a case temperature (Tcase) of -40°C to +85°C, so it can handle cold storage and freezer environments. Working humidity is rated 20-95% RH non-condensing, so ensure any condensation risk is managed by the enclosure design.
