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-C700B to drive dimmable LED arrays for architectural lighting?

Yes. The HLG-320H-C700B delivers 700mA constant current at up to 299.6W with a 3-in-1 dimming input (0-10VDC, 10V PWM, or resistance), making it suitable for architectural LED installations that require brightness control. The connected LED array's total forward voltage must fall within the 214-428V CC range.

Is the HLG-320H-C700B suitable for dimming long LED strip arrays in a retail display?

It can work for high-voltage LED strip arrays that operate within the 214-428V CC range at 700mA. The B suffix provides a dimming input for scene control or scheduled brightness changes in retail environments. Ensure your strip array's total forward voltage is within the supported range.

Can the HLG-320H-C700B power LED modules in a large outdoor sign with scheduled dimming?

Yes. At 299.6W and 700mA constant current, it can drive substantial LED sign arrays whose series voltage falls within 214-428V. The dimming input enables day/night brightness scheduling. The HLG-320H-C series is IP65 or IP67 approved depending on version, so confirm this model's rating before mounting it in a fully exposed outdoor location.

How does the HLG-320H-C700B differ from the HLG-320H-C700A and C700AB?

The -C700B provides a 3-in-1 dimming input (0-10VDC, 10V PWM, or resistance) but no output adjustment potentiometer. The -C700A has a potentiometer for current adjustment (350-700mA) but no dimming input. The -C700AB combines both features. All three share the same 299.6W, 700mA, 214-428V CC specs. Choose the B if you need dimming but not manual current trimming.

How many LEDs can I connect in series to the HLG-320H-C700B?

The count depends on each LED's forward voltage. This driver outputs 700mA constant current across a CC voltage range of 214-428V, which supports very long series strings. Sum your LEDs' forward voltages and confirm the total falls within that range. The high voltage range makes it especially suited for applications with many LEDs in series.

Can the HLG-320H-C700B handle cold-weather outdoor installations?

Yes. It is rated for a case temperature (Tcase) of -40°C to +85°C, making it suitable for cold climates including unheated outdoor enclosures. The series is IP65 or IP67 approved against dust and water. Over-temperature protection shuts the output down if the driver overheats, while the wide Tcase range supports startup in freezing conditions.
