Frequently Asked Questions
Can I use the HLG-320H-C1050A to power high-output LED floodlights?
Yes. The HLG-320H-C1050A delivers 1050mA constant current at up to 320.25W with a CC voltage range of 152-305V. This makes it well suited for high-output LED floodlights used in sports facility lighting, parking lot illumination, or building facade wash lights that require high-voltage series-connected LED arrays.
Is the HLG-320H-C1050A suitable for driving LEDs in large-format commercial signage?
Yes. At 320.25W and 1050mA constant current, this driver can power high-voltage LED strings in large channel letters, pylon signs, or monument sign cabinets. The built-in potentiometer lets you trim the output to match your specific LED string voltage within the 152-305V range.
Can I adjust the output of the HLG-320H-C1050A to match my LED load?
Yes. The A suffix indicates a built-in output adjustment potentiometer. This lets you fine-tune the constant-current output level to match your specific LED configuration without needing an external dimmer or controller. The CC voltage range spans 152-305V.
Is the HLG-320H-C1050A appropriate for high-bay LED lighting in industrial facilities?
Yes. With 320.25W at 1050mA, it handles high-bay fixtures with series LED strings in the 152-305V range. The IP65 water-resistant rating and -40°C to +85°C operating range suit factories, distribution centers, and covered industrial bays where dust and occasional moisture are present.
What total forward voltage range should my LED string have for the HLG-320H-C1050A?
Your series-connected LED string's total forward voltage should fall within 152-305V. The driver operates in constant-current mode at 1050mA. The exact number of LEDs you can wire in series depends on each LED's individual forward voltage — sum them to ensure the total stays in the 152-305V window.
Can I install the HLG-320H-C1050A outdoors under a canopy or in a ventilated cabinet?
Yes. The IP65 rating protects against dust ingress and low-pressure water jets, making it safe for covered outdoor locations such as canopy-mounted fixtures, ventilated electrical cabinets, or sheltered pole-mount enclosures. Avoid fully submerged installations.
