Frequently Asked Questions
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 (1-10V/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 rating with -40°C to +85°C operating 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. The IP65 rating handles greenhouse humidity levels.
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 (IP65). The C1400B has dimming input only (IP65). The C1400AB combines both adjustment and dimming (IP65). The C1400DA uses DALI protocol dimming and carries an IP67 waterproof rating for fully exposed outdoor installations.
