Frequently Asked Questions
Can I use the HLG-480H-48A to fine-tune output for a 48V LED lighting array?
Yes. The A suffix indicates a built-in potentiometer for adjusting output voltage and current. With a CC range of 24-48V, you can trim the 48V output to precisely match your LED array's optimal drive point. This is useful for maximizing efficiency or extending LED lifespan by avoiding over-driving.
Is the HLG-480H-48A suitable for powering 48V LED strips in a long commercial corridor?
Yes. At 480W and 48V, it can handle long LED strip runs common in commercial corridors. The 48V output reduces voltage drop over distance compared to lower-voltage drivers, and the adjustable output lets you compensate for any remaining drop by trimming the voltage slightly upward at the source.
Can the HLG-480H-48A drive 48V LED horticultural lighting in a greenhouse?
Yes. With 480W at 48V and 10A, it has capacity for high-power grow light panels. The adjustable output lets you dial in the exact drive current for different growth stages. However, its IP65 rating protects against water jets and dust but not submersion, so keep it away from direct flooding or standing water in the greenhouse.
How many meters of 48V LED strip can the HLG-480H-48A handle?
Divide 480W by the strip's power rating per meter. A 48V strip consuming 10W/m could run up to 48 meters (480W / 10W per meter = 48m). Always verify your strip's rated power per meter and ensure total load remains at or below 480W.
Is the HLG-480H-48A rated for damp indoor environments like parking garages?
Yes. Its IP65 water-resistant rating protects against dust and low-pressure water jets, which covers the splashing, dripping, and humidity found in parking garages, loading docks, and similar damp indoor spaces. For fully submerged or rain-exposed locations, choose the IP67-rated HLG-480H-48 or HLG-480H-48B.
