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-C700DA with a DALI-2 building automation system for LED high-bay lighting?

Yes, with a DALI controller it supports. The DA suffix indicates a DALI interface compliant with IEC62386-101 and 102 (207 by request); the sheet does not state DALI-2 certification, so confirm compatibility with your system. At 299.6W and 700mA constant current with a CC range of 214-428V, it can drive high-bay LED fixtures with long series strings. DALI control enables addressing (64 addresses), grouping (16 groups), and scene management.

Is the HLG-320H-C700DA suitable for outdoor LED signage controlled by a central DALI network?

Yes, within its IP rating. The series is IP65 or IP67 approved, so confirm this version's rating for fully exposed locations; the 700mA constant current with 214-428V CC range drives long LED module strings typical in large signs. The DALI interface enables centralized scheduling of brightness levels from a building management system.

Can I install the HLG-320H-C700DA in a location subject to temporary flooding?

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 C700DA, so confirm it before installing at ground level, in flood-prone areas, or where standing water may accumulate. An IP65 unit is not rated for immersion.

Can the HLG-320H-C700DA power LED arrays in a parking structure with DALI occupancy control?

Yes. At 299.6W and 700mA, it can drive high-output LED arrays for parking garage lighting with forward voltages summing to 214-428V. The DALI interface works with DALI controllers that use occupancy sensors and daylight harvesting, enabling zone-based dimming that reduces energy consumption in unoccupied areas.

How many LEDs can I drive in series with the HLG-320H-C700DA?

The number depends on each LED's forward voltage. The driver provides 700mA constant current with a CC voltage range of 214-428V, accommodating very long series strings. Sum your LEDs' forward voltages and verify the total stays within that window. The high voltage capability makes this driver ideal for applications requiring many series-connected LEDs.

What separates the HLG-320H-C700DA from the other C700 variants in the HLG-320H series?

The -C700DA uses a DALI interface for dimming. The -C700A has a potentiometer for current adjustment (350-700mA). The -C700AB adds both potentiometer and 3-in-1 dimming (0-10VDC, 10V PWM, or resistance). The -C700B has 3-in-1 dimming only. All share the same 299.6W, 700mA, 214-428V constant current specs; the series is IP65 or IP67 approved depending on version.
