Frequently Asked Questions
Can I use the HLG-320H-C2800A to drive high-power LED downlights in a retail space?
Yes. The HLG-320H-C2800A delivers 2800mA constant current at up to 319.2W, which can power multiple high-output LED downlight modules wired in series. Its adjustable output lets you fine-tune the current and voltage to match the exact LED load, which is useful when optimizing light levels for retail displays.
Is the HLG-320H-C2800A suitable for powering LED billboard or signage arrays?
Yes. At 319.2W and 2800mA, it can drive large LED sign modules whose string voltage falls within the 57-114V constant current range. The built-in adjustment potentiometer allows trimming the output to match your specific module configuration, and the wide 90-305VAC input handles varying commercial mains voltages.
Can the HLG-320H-C2800A power LED grow light fixtures?
Yes, provided the grow light operates within the 57-114V CC voltage range at 2800mA. The adjustable output is especially useful for grow lights where you may want to reduce drive current during seedling stages. Note that its IP65 rating protects against dust and water jets but not submersion, so keep it out of standing water.
How does the adjustable output on the HLG-320H-C2800A work?
The A suffix indicates a built-in potentiometer that lets you adjust the output current and voltage within the rated range. This allows on-site fine-tuning without external controllers, which is helpful for matching the driver precisely to your LED load or reducing output slightly for thermal management.
How many LEDs can I run in series with the HLG-320H-C2800A?
That depends on each LED's forward voltage. The CC voltage range is 57-114V, so you divide your target string voltage by the forward voltage of one LED. For example, if each LED has a 3V forward voltage, you could run roughly 19 to 38 LEDs in series. Always verify the total string voltage stays within 57-114V.
Can the HLG-320H-C2800A be used in a covered outdoor canopy?
Yes. Its IP65 water-resistant rating protects against dust ingress and low-pressure water jets, making it suitable for covered outdoor areas like canopies, soffits, and parking structures. For fully exposed installations with direct rain, consider the IP67-rated HLG-320H-C2800DA instead.
