Frequently Asked Questions
Can I use the HLG-480H-C1400A to power LED high-bay fixtures in a large industrial facility?
Yes. At 480W and 1400mA constant current with a CC voltage range of 171-343V, this driver is designed for high-power LED fixtures used in factories, warehouses, and distribution centers. The adjustable output lets you trim the current to match your specific fixture's requirements. Its -40°C to +90°C operating range covers demanding industrial environments.
Is the HLG-480H-C1400A suitable for powering long LED module strings in large-format signage?
Yes. The 1400mA constant current output with a 171-343V CC range supports long series strings of LED modules used in billboards and large illuminated signs. At 480W total output, it handles substantial LED arrays. The built-in potentiometer allows fine-tuning the current to optimize brightness uniformity across the sign.
Can I use the HLG-480H-C1400A for outdoor stadium or sports facility LED lighting?
The 480W output and 1400mA constant current make it powerful enough for stadium-grade LED fixtures with forward voltages summing to 171-343V. Its IP65 rating protects against dust and rain in sheltered mounting locations such as under canopies or inside ventilated enclosures. Fully exposed installations may need additional weather protection.
How many LEDs can I connect in series to the HLG-480H-C1400A?
The count depends on each LED's forward voltage. This driver outputs 1400mA constant current across a CC voltage range of 171-343V. Sum your LEDs' forward voltages and verify the total falls within that range. The high voltage window accommodates relatively long series strings, and the adjustable output lets you optimize the drive current.
Can the HLG-480H-C1400A operate in extreme temperature environments?
Yes. It is rated for -40°C to +90°C, one of the widest operating ranges in the HLG series. The aluminium casing and 262mm x 125mm x 43.8mm form factor provide effective heat dissipation at 2.8 kg. This makes it suitable for unheated cold-storage facilities, desert installations, or rooftop equipment housings.
What does the 'A' suffix mean on the HLG-480H-C1400A compared to the AB variant?
The -C1400A includes a built-in potentiometer for output current adjustment but no dimming signal input. The -C1400AB adds both a potentiometer and a 1-10V/PWM dimming input, enabling external brightness control from dimmers or building automation. Both share the same 480W, 1400mA, 171-343V specs and IP65 rating.
