Frequently Asked Questions
Can I use the HLG-120H-48A to power 48V LED strip lighting in a covered outdoor area?
Yes. The HLG-120H-48A delivers 48V at up to 2.5A (120W) and has an IP65 water-resistant rating, so it handles splashing water and dust in covered patios, canopies, or soffits. For fully exposed rain installations, consider the IP67-rated HLG-120H-48 or HLG-120H-48B instead.
Is the adjustable output on the HLG-120H-48A useful for matching different 48V LED loads?
Yes. The built-in potentiometer lets you trim the output voltage and current, which helps when your LED fixture operates best at a slightly lower drive level. The CC voltage range is 24-48V, giving you room to lower the output without needing an external dimmer.
Can the HLG-120H-48A drive 48V LED modules for commercial signage?
Yes. At 120W and 48V output, it can power 48V channel letters, light boxes, or cabinet sign modules. The adjustable output is useful for matching the driver precisely to the module string voltage. Its 90-305VAC input handles most commercial mains supplies worldwide.
How many meters of 48V LED strip can the HLG-120H-48A handle?
Divide 120W by your strip's power consumption per meter. For instance, a strip rated at 15W/m would allow about 8 meters (120W / 15W per meter = 8m). Always check your strip's rated power per meter and keep total load at or below 120W for reliable operation.
Is the HLG-120H-48A suitable for a damp basement or garage installation?
Yes. IP65 protects against low-pressure water jets and dust ingress, which is more than sufficient for damp indoor environments like basements, garages, or parking structures. For locations with direct rain or standing water, the IP67-rated HLG-120H-48 would be more appropriate.
