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).

FAQ
Can I use the HLG-320H-C1750DA for DALI-controlled LED street lighting?
Yes. The HLG-320H-C1750DA provides 1750mA constant current at up to 320.25W with DALI digital dimming (IEC62386-101, 102). The series is IP65 or IP67 approved, so confirm this version's rating before exposing it to rain, snow, or flooding inside street light poles or fixture housings. The DALI bus enables centralized scheduling and dimming across multiple luminaires.
Is the HLG-320H-C1750DA suitable for outdoor LED floodlights at a sports field?
Yes. The 320.25W output at 1750mA can drive high-power floodlight LED modules with string voltages in the 91-183V range. The DALI interface lets a central controller dim or switch fixtures for different event lighting scenes. The series is IP65 or IP67 approved; confirm this version's rating for direct weather exposure at the top of lighting poles.
Can I integrate the HLG-320H-C1750DA into a smart building lighting network?
Yes. The DALI interface (IEC62386-101, 102) allows individual addressing (64 addresses), group control (16 groups), and scene management through any DALI-compatible building automation system. This supports daylight harvesting, occupancy response, and scheduled dimming profiles run by the controller.
Can the HLG-320H-C1750DA be mounted in a location that may flood temporarily?
Only if this version is IP67-rated. The HLG-320H-C series is IP65 or IP67 approved, and the sheet does not assign a rating to the C1750DA, so confirm it first. An IP67 unit can handle temporary immersion but is not designed for permanent submersion; an IP65 unit is not rated for immersion. For flood-prone trenches, ensure drainage is adequate.
How do I confirm the HLG-320H-C1750DA will work with my LED modules?
Check that your LED modules require 1750mA drive current and that the total series string voltage at that current falls within 91-183V. Also verify your DALI controller supports IEC62386 devices; IEC62386-207 compliance is available by request. The driver automatically adjusts voltage to maintain 1750mA through the connected LED load.
How does the HLG-320H-C1750DA differ from the HLG-320H-C1750B?
Both deliver 1750mA at up to 320.25W with the same 91-183V CC range. The key difference is the dimming interface. The -C1750B uses analog 3-in-1 dimming (0-10VDC, 10V PWM, or resistance), while the -C1750DA uses DALI digital dimming (IEC62386-101, 102). The series is IP65 or IP67 approved depending on version. Choose DALI for digital building networks and -B for simple analog dimming.
