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-C1400AB with a dimming controller for automated LED lighting scenes?

Yes. The AB suffix means this driver has both a potentiometer for output adjustment and a dimming signal input (0-10VDC/10V PWM/resistance). You can set the maximum output level with the potentiometer and use the dimming input for dynamic scene control via a lighting controller or building automation system.

Is the HLG-320H-C1400AB suitable for dimmable LED high-mast or area lighting?

Yes. At 320.6W and 1400mA constant current with a CC range of 114-229V, it can power high-mast LED fixtures for parking lots, roadways, or large commercial areas. The dimming input enables nighttime power reduction, and the IP65/IP67-approved enclosure with a -40°C to +85°C case temperature (Tcase) range handles outdoor conditions.

Can the HLG-320H-C1400AB drive dimmable horticultural LED arrays in a greenhouse?

Yes, provided the array accepts 1400mA constant-current drive with total forward voltage between 114V and 229V. The dimming input lets you control light intensity for different growth phases, and the potentiometer allows fine-tuning maximum output. Working humidity is rated 20-95% RH non-condensing, so keep condensation off the driver in humid greenhouses.

Can I use the HLG-320H-C1400AB for dimmable retrofit LED fixtures in a retail space?

Yes. The 320.6W output at 1400mA drives high-power retail LED fixtures with series strings in the 114-229V range. The dimming capability enables ambient lighting adjustments for different store hours or merchandise displays, and the adjustable output helps match the driver to the specific fixture requirements.

How do I determine if my LED load is compatible with the HLG-320H-C1400AB?

Verify that your LED load operates at 1400mA constant current and that the total forward voltage of your series string falls within 114-229V. The driver will regulate the current at 1400mA regardless of where the voltage settles in that range. The number of series LEDs depends on each LED's individual forward voltage.

What are the differences between the HLG-320H-C1400A, C1400AB, C1400B, and C1400DA?

All four share the same 320.6W / 1400mA / 114-229V CC core specs. The C1400A has potentiometer adjustment only (700-1400mA). The C1400B has dimming input only. The C1400AB combines both adjustment and dimming. The C1400DA uses DALI protocol dimming. The series is IP65 or IP67 approved depending on version, so confirm the rating before fully exposed outdoor installations.
