Frequently Asked Questions
Can I use the HLG-320H-C2100A to drive high-current LED COB modules for industrial lighting?
Yes. The HLG-320H-C2100A outputs 2100mA constant current at up to 319.2W, well suited for high-current COB LED modules used in industrial high-bay or area lighting. The LED string voltage must fall within the 76-152V range. The built-in potentiometer lets you reduce the drive current to match your specific COB module's recommended operating point.
Is the HLG-320H-C2100A suitable for LED grow lights requiring 2100mA drive current?
Yes. At 2100mA and 319.2W, it can power demanding horticultural LED modules whose string voltage falls within 76-152V. The adjustable output current lets you fine-tune light intensity to match different growth stages or plant species without adding external dimmers.
Can the HLG-320H-C2100A power LED luminaires in a cold storage facility?
Yes. The operating temperature range of -40°C to +85°C makes it fully suitable for cold storage and freezer environments. The 319.2W output at 2100mA drives high-output luminaires needed in large refrigerated spaces. The aluminium casing ensures effective heat dissipation even at low ambient temperatures.
What does the adjustable output on the HLG-320H-C2100A do?
The built-in potentiometer lets you reduce the constant-current output from the factory-set 2100mA to a lower value within the design range. This allows permanent calibration to match a specific LED module's optimal drive current, reducing thermal stress and potentially extending LED lifetime without requiring an external controller.
How do I determine the correct LED string configuration for the HLG-320H-C2100A?
Sum the forward voltages of each LED in your series string at 2100mA. The total must fall within the 76-152V constant-current output range. The exact LED count depends on each LED's forward voltage at that current. Operating near the middle of the voltage range provides the best regulation margin.
Can the HLG-320H-C2100A be used outdoors under a building overhang?
Yes. The IP65 rating protects against dust and low-pressure water jets, making it suitable for sheltered outdoor positions like overhangs, soffits, or inside ventilated enclosures. The -40°C to +85°C operating range handles seasonal extremes. For fully exposed outdoor mounting, consider the IP67-rated HLG-320H-C2100DA.
