The linked HLG-320H specification supplies the model-specific ratings and A-type function details. Check its load curves before operation at high case temperature or low AC input voltage.
Matching the driver to a 24V lighting load
Confirm the LED load’s voltage, current and control requirements. Constant-voltage loads must stay within the driver’s output ratings; constant-current operation must stay within the specified operating region. The A model does not provide the external 3-in-1 dimming input found on B and AB versions.
Frequently asked questions
How much power does the HLG-320H-24A provide?
Its model-specific rating is 24V, 13.34A and 320.16W. HLG-320H is the series designation.
Can I adjust the voltage and current?
Yes. Built-in potentiometers provide 21–26V voltage adjustment and 6.67–13.34A current adjustment. Set them to suit the connected LED load.
Is the HLG-320H-24A dimmable with a 1–10V signal?
The A model has built-in adjustment only. The datasheet lists external 3-in-1 dimming for B and AB versions, so verify the full suffix when choosing a control method.
What are the enclosure size and IP rating?
The A version is IP65 and measures 252 × 90 × 43.8mm. Installation and wiring must follow the datasheet and preserve the protection of the complete lighting assembly.
