Frequently Asked Questions
Can I use the HLG-480H-C1750AB for dimmable high-bay industrial LED lighting?
Yes. The HLG-480H-C1750AB provides 480W at 1750mA constant current with both output adjustment and external dimming input (1-10V/PWM). This makes it ideal for warehouse or factory high-bay fixtures where you need to dim lights based on occupancy or daylight harvesting while also fine-tuning the drive current to match your specific LED modules.
Is the HLG-480H-C1750AB a good choice for dimmable LED grow lights?
Yes. At 480W and 1750mA, it supplies enough power for high-output horticultural fixtures. The AB suffix means you can adjust the output current via potentiometer for optimal plant-spectrum tuning and dim externally via 1-10V or PWM signal to simulate sunrise/sunset cycles or adjust intensity for different growth stages.
Can I use the HLG-480H-C1750AB for dimmable outdoor architectural LED floodlights?
Yes. The 1750mA constant current output across 137-274V suits high-power floodlight arrays for building facades or landscape features. The dimming input allows scene control through a building management system, and the IP65 rating protects the driver in covered outdoor mounting locations.
What dimming methods does the HLG-480H-C1750AB support?
The AB suffix indicates the driver accepts 1-10V analog and PWM dimming signals via an external input. The built-in potentiometer also allows manual adjustment of the output current. These two features can be used independently or together to set a maximum current level via the potentiometer and then dim below that level with the external signal.
What LED string voltage range is compatible with the HLG-480H-C1750AB?
The constant current output voltage range is 137-274V. Your series LED string's total forward voltage must fall within this range for the driver to regulate at 1750mA. The exact number of LEDs you can connect depends on each LED's individual forward voltage.
Can the HLG-480H-C1750AB be mounted in a dusty manufacturing environment?
Yes. The IP65 rating means the aluminium enclosure is fully sealed against dust ingress and protected from low-pressure water jets. This suits factories, workshops, and processing plants where airborne particulates and occasional washdown spray are present. The -40 to +90 degree Celsius operating range also handles unheated industrial spaces.
