Frequently Asked Questions
Can I use the HLG-480H-C2800AB to drive high-power LED grow lights?
Yes. The HLG-480H-C2800AB delivers 479W at a constant current of 2800mA with a CC voltage range of 85-171V, which suits high-power LED arrays commonly used in horticultural lighting. Its IP65 rating and -40°C to +90°C operating range also allow installation in greenhouse environments.
Is the HLG-480H-C2800AB suitable for powering large LED high-bay fixtures?
Yes. At 479W and 2800mA constant current, it can drive high-bay LED fixtures used in warehouses, factories, and gymnasiums. The wide 90-305VAC input handles global mains voltages, and the aluminium casing with IP65 protection allows mounting in dusty or damp industrial settings.
Can I dim and adjust the output of the HLG-480H-C2800AB?
Yes. The AB suffix means this model includes both a built-in potentiometer for output adjustment and a dimming input that accepts 1-10V, PWM, or resistance signals. This makes it well-suited for applications where you need precise current tuning and external dimming control, such as architectural or horticultural lighting scenes.
Can the HLG-480H-C2800AB drive LED street light or parking lot fixtures?
Yes. Its 479W output at 2800mA constant current and IP65 water-resistant rating make it appropriate for outdoor area lighting such as street lights and parking lot fixtures. The wide operating temperature range of -40°C to +90°C handles extreme seasonal conditions.
How many LEDs can I run in series with the HLG-480H-C2800AB?
The number of LEDs depends on each LED's forward voltage. The CC voltage range is 85-171V, so your total series string voltage must fall within that window. Divide 85-171V by your LED's forward voltage to estimate the minimum and maximum number of LEDs in one series string.
Can the HLG-480H-C2800AB be installed outdoors in an exposed location?
It carries an IP65 water-resistant rating, which protects against low-pressure water jets and dust. This is sufficient for sheltered outdoor locations such as canopies, soffits, or ventilated enclosures. For fully submerged or standing-water conditions, an IP67-rated enclosure or alternative driver would be more appropriate.
