Frequently Asked Questions
Can I use the HLG-120H-30A for 30V LED strip installations under an awning or canopy?
Yes. The HLG-120H-30A delivers 30V at up to 4A (120W) with an IP65 water-resistant rating, which handles splashing water and dust in sheltered outdoor locations such as awnings, canopies, and covered walkways. For fully exposed rain installations, the IP67-rated HLG-120H-30 would be more appropriate.
Is the adjustable output on the HLG-120H-30A helpful for matching different 30V LED loads?
Yes. The built-in potentiometer lets you trim the output voltage and current to match the specific requirements of your 30V LED load. The CC voltage range extends from 15V to 30V, giving you flexibility to lower the drive level for loads that operate best below the full 30V.
Can the HLG-120H-30A power 30V LED modules for illuminated menu boards or light boxes?
Yes. At 120W and 30V output, it can drive a sizeable array of 30V LED modules for indoor or sheltered light boxes and menu boards. The adjustable output lets you dial in the precise voltage needed, and the wide 90-305VAC input accommodates most commercial mains voltages.
How many meters of 30V LED strip can the HLG-120H-30A handle?
Divide 120W by your strip's power consumption per meter. For a strip rated at 12W/m, that allows up to 10 meters (120W / 12W per meter = 10m). For a strip at 20W/m, the limit is 6 meters. Check your strip's rated power per meter and keep total load at or below 120W.
Is the HLG-120H-30A suitable for an indoor warehouse or garage with occasional moisture?
Yes. The IP65 rating protects against low-pressure water jets from any direction and complete dust ingress, making it well suited for warehouses, garages, and damp indoor environments. For locations with standing water or full rain exposure, the IP67-rated HLG-120H-30 is a better choice.
