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-C1400DA to power LED street light fixtures with DALI control?

Yes. The HLG-320H-C1400DA outputs 1400mA constant current at up to 320.6W and supports DALI digital dimming (IEC62386-101, 102), making it suitable for smart street lighting systems. The series is IP65 or IP67 approved, so confirm this version's rating before mounting it inside pole bases or fixture housings exposed to weather.

Is the HLG-320H-C1400DA suitable for outdoor LED floodlights in a parking lot?

Yes. The 320.6W output at 1400mA provides ample power for high-output LED floodlight modules whose string voltage falls within the 114-229V range. The IP65/IP67-approved enclosure suits outdoor use (confirm this version's rating for direct rain and pooling), and the DALI interface enables centralized dimming schedules for energy management across the lot.

Can I integrate the HLG-320H-C1400DA into a building management system?

Yes. The DALI interface (IEC62386-101, 102) on the HLG-320H-C1400DA allows integration with DALI-compatible building automation controllers. This enables scheduled dimming, daylight harvesting, and occupancy-based control. The driver can be addressed individually (64 addresses) or as part of one of 16 DALI groups on a shared two-wire bus.

Can the HLG-320H-C1400DA drive LED arrays for large illuminated signage outdoors?

Yes, provided the LED string voltage at 1400mA falls within 114-229V. The 320.6W capacity supports demanding sign loads, and the DALI control lets you remotely adjust brightness. The series is IP65 or IP67 approved; confirm this version's rating before using it in exposed outdoor enclosures without additional weatherproofing.

How do I determine if the HLG-320H-C1400DA is compatible with my LED load?

Verify that your LED module or string requires 1400mA drive current and that its total forward voltage falls within the 114-229V constant-current range. The driver will automatically adjust its output voltage to maintain 1400mA through the load. Also confirm your DALI controller supports IEC62386 DALI devices for full dimming functionality.

Can the HLG-320H-C1400DA withstand installation in a coastal environment?

The HLG-320H-C series is IP65 or IP67 approved, so the enclosure is dust-tight and protected against water, and its -40°C to +85°C case temperature (Tcase) range suits coastal climates. The sheet gives no salt-spray rating, so in highly corrosive coastal environments additional protective measures such as a secondary enclosure are still recommended.
