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-C1050DA with a DALI lighting control system?

Yes. The DA suffix indicates a built-in DALI interface compliant with IEC62386-101 and 102 (207 by request). You can integrate this driver directly into a DALI bus for centralized dimming control and scene management, with 16 groups and 64 addresses. It delivers 1050mA constant current at up to 320.25W across a 152-305V range.

Is the HLG-320H-C1050DA suitable for outdoor LED fixtures fully exposed to rain?

It depends on the version's rating. The HLG-320H-C series is IP65 or IP67 approved, but the sheet does not state which rating applies to the C1050DA, so confirm it before exposing the driver directly to rain, ground-recessed fixtures, or locations where standing water is expected. Its -40°C to +85°C case temperature range suits outdoor climates.

Can I use the HLG-320H-C1050DA for smart building LED lighting with automated scheduling?

Yes. DALI enables individual fixture addressing (64 addresses), group dimming (16 groups), and scheduled scene changes through a DALI controller or building automation system. The 320.25W output at 1050mA handles demanding commercial fixtures, and the IP65/IP67-approved enclosure allows placement indoors and in sheltered outdoor locations.

Is the HLG-320H-C1050DA a good fit for LED tunnel or underpass lighting on a DALI bus?

Yes. Tunnel lighting often requires DALI control for daylight-adaptive dimming at entry and exit zones. This driver provides 1050mA constant current at up to 320.25W, and the series is IP65 or IP67 approved against dust and moisture. The -40°C to +85°C case temperature (Tcase) range covers seasonal extremes.

What is the LED string voltage requirement for the HLG-320H-C1050DA?

The constant-current operating range is 152-305V at 1050mA. configure your LEDs in series so the combined forward voltage falls within this window. The exact LED count depends on each LED's forward voltage — sum them and verify the total is between 152V and 305V.

How do the IP65 and IP67 ratings of the HLG-320H-C1050 variants compare?

IP65 protects against dust and water jets, suitable for sheltered outdoor or indoor locations. IP67 adds protection against temporary immersion in water. The sheet lists the HLG-320H-C series as IP65 or IP67 approved without assigning a rating to each version, so confirm the C1050DA's rating before using it where heavy rain, flooding risk, or pooling water is possible.
