Frequently Asked Questions
Can I use the HLG-40H-15AB to power 15V LED strip lighting in a covered outdoor sign?
Yes. The HLG-40H-15AB delivers 15V at up to 2.67A (40W) and has an IP65 water-resistant rating, so it can handle sheltered outdoor locations like sign cabinets or canopied installations. The adjustable output also lets you fine-tune voltage and current to match your specific LED strip requirements.
Is the HLG-40H-15AB suitable for dimmable 15V LED accent lighting in a retail display?
It is a good fit for small-scale retail accent lighting where brightness control matters. The HLG-40H-15AB supports dimming via 1-10V, PWM, and resistance signals, plus the built-in potentiometer allows you to set the baseline output. Total load must remain at or below 40W.
Can I use the HLG-40H-15AB to drive a 15V LED light box with dimming?
Yes, provided the light box draws 40W or less. The HLG-40H-15AB outputs 15V at up to 2.67A in constant-current mode and accepts dimming signals, letting you reduce brightness for ambient settings or energy savings. Its 90-305VAC input handles most global mains voltages.
How many meters of 15V LED strip can the HLG-40H-15AB handle?
That depends on your strip's rated power per meter. The HLG-40H-15AB provides 40W at 15V. For example, if your strip draws 8W per meter, you could run up to 5 meters (40W / 8W per meter = 5m). Always check your strip's rated power per meter and keep total load at or below 40W.
Can the HLG-40H-15AB handle outdoor installations exposed to rain?
The HLG-40H-15AB is rated IP65, which protects against dust and low-pressure water jets, but it is not rated for submersion or heavy direct water exposure. It works well in sheltered outdoor settings such as covered walkways or enclosed sign cabinets. For fully exposed wet locations, consider the IP67-rated HLG-40H-15B instead.
What is the difference between the HLG-40H-15AB and HLG-40H-15B?
Both deliver 15V at 2.67A for the same 40W-class load. The HLG-40H-15AB offers both adjustable output (potentiometer) and dimming capability with an IP65 water-resistant rating. The HLG-40H-15B provides dimming without adjustable output but has a higher IP67 waterproof rating suitable for fully exposed wet locations.
