Test conditions and notes11

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
11. For A/AB type need to consider build in using to comply with Type HL application.

FAQ

Can I use the HLG-320H-C700AB to power dimmable LED high-bay fixtures in a warehouse?

Yes. The HLG-320H-C700AB provides 700mA constant current at up to 299.6W with both an adjustable output and a 3-in-1 dimming input (0-10VDC, 10V PWM, or resistance). This allows daylight harvesting or occupancy-based dimming in warehouse high-bay installations. The fixture's forward voltage must fall within the 214-428V CC range.

Is the HLG-320H-C700AB a good choice for dimmable commercial LED signage?

Yes. The 700mA constant current output across a 214-428V CC range can drive long series strings of LED modules used in channel letters and large illuminated panels. The dimming input allows scheduling day and night brightness levels, and the adjustable potentiometer lets you trim current to your modules' optimal operating point.

Can I use the HLG-320H-C700AB with a 0-10V building automation dimmer?

Yes. The AB suffix indicates a 3-in-1 dimming input that accepts 0-10VDC, a 10V PWM signal, or resistance, so it works with 0-10V signals from building automation systems, occupancy sensors, or standalone dimmers. Combined with the potentiometer for maximum current adjustment (350-700mA), you get full control over light output from the connected LED string.

Can the HLG-320H-C700AB be mounted in a covered outdoor location?

Yes. The HLG-320H-C series is IP65 or IP67 approved for dust and water protection, suitable for soffits, ventilated enclosures, or covered canopies. If the installation may be exposed to standing water or heavy flooding, confirm this version's IP rating first.

How many LEDs can I run in series with the HLG-320H-C700AB?

The exact number depends on each LED's forward voltage. The driver operates at 700mA constant current with a CC voltage range of 214-428V, which accommodates very long LED series strings. Sum the forward voltages of your LEDs and confirm the total falls within that range. The built-in potentiometer allows fine-tuning the output.

What is the operating temperature range of the HLG-320H-C700AB?

The HLG-320H-C700AB is rated for a case temperature (Tcase) of -40°C to +85°C; output may need derating at higher temperatures per the load-vs-temperature curve. In enclosed spaces near the upper limit, provide adequate airflow or reduce the load. Life expectancy exceeds 62,000 hours with Tcase at about 75°C or less.
