Frequently Asked Questions
Can I use the HLG-40H-48A to fine-tune output for 48V LED fixtures?
Yes. The HLG-40H-48A includes a built-in potentiometer that lets you trim both output voltage and current. This is useful when your 48V LED fixtures need a slightly lower or more precise drive level than the nominal 48V, without requiring an external controller.
Is the HLG-40H-48A suitable for 48V LED strip lighting in a retail display?
Yes. At 40W and 48V it can power short runs of 48V LED strip common in retail showcases and shelf lighting. The adjustable output lets you calibrate brightness to the exact level needed for product displays, and the compact 171 x 61.5 x 36.8 mm form factor fits in tight spaces.
Can the HLG-40H-48A power 48V LED modules for compact commercial signage?
Yes, as long as the total module load stays within 40W. The adjustable output lets you match the driver precisely to the module string voltage within the 28-48V CC range. The wide 90-305VAC input handles most commercial mains voltages worldwide.
How many meters of 48V LED strip can the HLG-40H-48A drive?
It depends on the strip's power consumption per meter. The HLG-40H-48A provides up to 40W at 48V. If your strip draws 10W/m, you could power up to 4 meters (40W / 10W per meter = 4m). Check your strip's rated power per meter and keep total draw at or below 40W.
Can the HLG-40H-48A be installed in a damp indoor location or sheltered outdoor area?
Yes. Its IP65 water-resistant rating protects against dust and low-pressure water jets, which covers damp basements, industrial kitchens, and covered outdoor locations. For fully exposed rain installations, the IP67-rated HLG-40H-48 would be the better choice.
