Frequently Asked Questions
Can I use the HLG-480H-C2100AB for dimmable warehouse high-bay LED fixtures?
Yes. The HLG-480H-C2100AB delivers 481W at 2100mA with both current adjustment and external dimming input (1-10V/PWM). This supports occupancy-based or daylight-harvesting dimming in warehouse high-bay installations. The potentiometer lets you set the peak current to match your fixture's LED modules precisely.
Is the HLG-480H-C2100AB a good fit for dimmable commercial LED grow lights?
Yes. At 481W and 2100mA, this driver handles high-intensity horticultural fixtures. The AB suffix gives you both a potentiometer for current fine-tuning and an external dimming interface for automated light recipes, sunrise/sunset simulation, or integration with greenhouse climate control systems.
Can the HLG-480H-C2100AB power dimmable LED floodlights for building facade lighting?
Yes. The 2100mA constant current output across 114-229V drives high-power floodlight LED arrays. The dimming input enables architectural lighting scenes and scheduled brightness profiles through a building automation system. The IP65 rating suits mounting in covered outdoor locations near the illuminated facade.
What dimming and adjustment features does the HLG-480H-C2100AB offer?
The AB suffix means this driver has two control features: a built-in potentiometer for manually adjusting the output current, and an external dimming input that accepts 1-10V analog or PWM signals. You can set a maximum current with the potentiometer and then use the dimming signal to reduce output below that level.
What LED string voltage is required for the HLG-480H-C2100AB?
The constant current output voltage range is 114-229V. Your series LED string's total forward voltage must fall within this range for the driver to regulate properly at 2100mA. The number of LEDs in the string depends on each LED's individual forward voltage.
Can the HLG-480H-C2100AB be installed in a dusty food-processing or industrial facility?
Yes. The IP65-rated aluminium enclosure is fully sealed against dust ingress and withstands low-pressure water jets, making it suitable for food-processing plants, flour mills, woodworking shops, and similar dusty environments. The operating range of -40 to +90 degrees Celsius also handles unheated or high-temperature industrial spaces.
