Test conditions and notes10
- 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

FAQ
Can I use the HLG-320H-C1750B to drive dimmable LED high-bay lights in a sports facility?
Yes. The HLG-320H-C1750B delivers 1750mA constant current at 320.25W and includes a 3-in-1 dimming input (0-10VDC, 10V PWM, or resistance). This allows you to reduce light levels during practice sessions and ramp up to full brightness for competitions. The LED modules must have a string voltage within the 91-183V range.
Is the HLG-320H-C1750B suitable for LED retail display lighting with brightness control?
Yes, provided your LED fixtures require 1750mA and the string voltage falls within 91-183V. The dimming input accepts 0-10VDC, 10V PWM, or resistance, letting you adjust ambiance for product displays. At 320.25W, it can handle substantial LED loads across multiple fixture strings wired in series.
Can the HLG-320H-C1750B power LED luminaires in a workshop or factory floor?
Yes. The 320.25W capacity and 1750mA drive current suit industrial LED luminaires with string voltages in the 91-183V range. The dimming function via 0-10VDC, PWM, or resistance allows task-based lighting control. The driver's -40°C to +85°C case temperature (Tcase) range and IP65/IP67-approved enclosure handle typical industrial conditions.
Can I use the HLG-320H-C1750B for outdoor architectural LED accent lighting?
It can work in sheltered outdoor locations. The HLG-320H-C series is IP65 or IP67 approved against dust and water, making it suitable for installation inside weatherproof junction boxes or under eaves. For fully exposed outdoor positions, confirm this version's IP rating first.
How do I size the LED string for the HLG-320H-C1750B?
The driver outputs a constant 1750mA and adjusts its voltage automatically within the 91-183V range to maintain that current. Add up the forward voltages of all LEDs in your series string at 1750mA and confirm the total falls within this range. The exact number of LEDs depends on each LED's individual forward voltage.
What dimming methods does the HLG-320H-C1750B support?
The HLG-320H-C1750B accepts three dimming methods between DIM+ and DIM-: 0-10VDC, a 10V PWM signal (100Hz-3kHz), or resistance; the minimum dimming level is about 6%. It does not include output current adjustment via potentiometer — for that feature combined with dimming, you would need the HLG-320H-C1750AB. The -B variant suits systems where external dimming control is sufficient.
