Frequently Asked Questions
Can I use the HLG-185H-48A to power 48V LED strips in a covered outdoor area?
Yes. The HLG-185H-48A delivers 48V at up to 3.9A (185W) with 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-185H-48 or -48B instead.
Is the adjustable output on the HLG-185H-48A useful for fine-tuning LED brightness?
Yes. The built-in potentiometer lets you trim the output voltage and current without an external dimmer. The CC voltage range is 24-48V, so you can lower the drive level to match your specific LED load or reduce brightness slightly for the desired effect.
Can the HLG-185H-48A power 48V LED modules for commercial signage?
Yes. At 185W and 48V, it can drive 48V channel letters, light boxes, or cabinet sign modules. The adjustable output is useful for precisely matching driver voltage to the module string voltage, and the wide 90-305VAC input handles most commercial mains supplies.
Can the HLG-185H-48A drive 48V architectural or cove lighting?
Yes. The 185W output at 48V suits medium-power architectural fixtures such as linear cove lights, wall washers, and accent strips. The built-in adjustment lets you dial in the exact output voltage for optimal performance across varying LED forward voltages within the 24-48V CC range.
How many meters of 48V LED strip can the HLG-185H-48A handle?
Divide 185W by your strip's power consumption per meter. For instance, a 48V strip rated at 10W/m would allow about 18.5 meters (185W / 10W per meter). Always check your strip's rated power per meter and keep the total load at or below 185W.
Is the HLG-185H-48A suitable for a damp warehouse or parking garage?
Yes. IP65 protects against low-pressure water jets and dust ingress, which is more than sufficient for damp indoor environments like warehouses, parking garages, or wash-down areas. For locations with direct rain or potential standing water, the IP67-rated HLG-185H-48 is more appropriate.
