A-Type Adjustment and Installation
Voltage and current are set through the built-in potentiometers. External 3-in-1 dimming is a feature of other suffix versions, so check the complete model code if the project requires a dimming control input.
Match the LED string voltage and operating current to the driver’s output region. Use the specification’s load curves for low input voltage and elevated case temperature, and protect cable connections according to the installation conditions.
Frequently Asked Questions
Is HLG-320H-42A a constant-current driver?
It supports both constant-voltage and constant-current operation. The specified constant-current region is 21–42V.
What output power is specified for the 42V model?
The exact rating is 321.3W at 42V and 7.65A within the HLG-320H series.
Can I adjust its voltage and current?
Yes. The A version provides built-in adjustments of 38–45V and 3.8–7.65A.
Does the A version support external 3-in-1 dimming?
No. The A version uses local potentiometer adjustment. Check the appropriate B or AB variant when external dimming is required.
Is HLG-320H-42A IP65 or IP67?
The A suffix is IP65. The IP67 rating shown for some other HLG-320H versions should not be applied to this model.
