Frequently Asked Questions
Can I use the HLG-80H-20AB to power and dim 20V LED strip lighting?
Yes. The HLG-80H-20AB delivers 20V at up to 4A (80W) and includes both an adjustable output potentiometer and a 1-10V/PWM dimming input. You can set a baseline brightness with the potentiometer and then vary it further via a dimmer or automation system.
Is the HLG-80H-20AB suitable for smart lighting systems that need dimming control?
Yes. Its 1-10V/PWM dimming input is compatible with most building management systems and smart lighting controllers. This makes it practical for conference rooms, retail displays, or hospitality lighting where automated brightness scheduling is needed, with 80W of capacity at 20V.
Can the HLG-80H-20AB drive 20V LED channel-letter signs with adjustable brightness?
Yes. At 80W and 20V, it can power 20V sign modules. The built-in potentiometer fine-tunes voltage to match the module string, while the dimming input allows automated day/night brightness control. The wide 90-305VAC input handles varying mains voltages at commercial sites.
How many meters of 20V LED strip can the HLG-80H-20AB handle?
That depends on your strip's rated power per meter. The HLG-80H-20AB provides up to 80W at 20V. If your strip draws 8W/m, you could run up to 10 meters (80W / 8W per meter = 10m). Check your strip's rated power per meter and keep total load at or below 80W.
Can the HLG-80H-20AB be installed in a sheltered outdoor location like a covered walkway?
Yes. Its IP65 water-resistant rating protects against low-pressure water jets and dust, which is sufficient for covered walkways, awnings, and sheltered outdoor areas. For fully exposed rain installations, consider the IP67-rated HLG-80H-20B which also offers dimming.
