Frequently Asked Questions
Can I use the HLG-320H-20AB with a 1-10V dimmer to control high-power 20V LED strip installations?
Yes. The HLG-320H-20AB accepts 1-10V and PWM dimming signals and delivers up to 300W at 20V, so you can pair with a wall dimmer or automation controller to smoothly adjust brightness on large 20V LED strip runs. The built-in potentiometer also lets you set the maximum output level.
Is the HLG-320H-20AB suitable for powering 20V LED channel-letter signage with dimming control?
Yes. At 300W and 20V output with 1-10V/PWM dimming input, it can drive large 20V channel-letter or cabinet sign arrays while allowing brightness scheduling. Its wide 90-305VAC input handles most commercial mains voltages worldwide.
Can the HLG-320H-20AB power a smart-home controlled 20V LED lighting system?
Yes. The dimming input (1-10V/PWM) can be driven by most smart-home controllers or building automation systems. With 300W at 20V and an adjustable output potentiometer, you get both automated dimming and manual fine-tuning of the drive level.
How many meters of 20V LED strip can the HLG-320H-20AB power?
Divide 300W by your strip's rated power per meter. For example, a strip drawing 14W/m allows up to about 21.4 meters (300W / 14W per meter). Always check your strip's rated power per meter and keep the total load at or below 300W.
Can the HLG-320H-20AB be installed in a sheltered outdoor location like a soffit or canopy?
Yes. Its IP65 water-resistant rating protects against dust and low-pressure water jets, making it suitable for covered outdoor areas such as soffits, canopies, and awnings. For fully exposed rain installations, the IP67-rated HLG-320H-20B is a better choice.
What is the operating temperature range of the HLG-320H-20AB for outdoor use?
The HLG-320H-20AB operates from -40°C to +90°C, covering extreme cold and hot climates. This wide range means it can be deployed in freezing northern winters or hot desert summers without derating under most real-world conditions.
