Frequently Asked Questions
Can I use the HLG-320H-30AB for dimmable outdoor 30V LED strip lighting?
Yes. The HLG-320H-30AB delivers 320W at 30V with both adjustable output and dimming capability via 1-10V, PWM, or resistance signals. However, it carries an IP65 water-resistant rating, so it should be mounted in a sheltered location such as a covered enclosure or canopy rather than fully exposed to rain or submersion.
Is the HLG-320H-30AB suitable for powering dimmable 30V LED channel letter signage?
It is a strong fit for medium to large channel letter sign installations requiring dimming control. At 320W and 30V output, it can drive a significant number of LED modules, and the adjustable output lets you fine-tune voltage within the 15-30V constant-current range. Mount the driver inside the sign cabinet to respect the IP65 rating.
Can I power a 30V dimmable LED light box or backlit display with the HLG-320H-30AB?
Yes, as long as the total load stays at or below 320W. The built-in potentiometer lets you dial in the baseline output while the dimming input provides scene-based brightness control. Its wide 90-305VAC input means it works on virtually any mains supply worldwide.
How many meters of 30V LED strip can the HLG-320H-30AB support?
Divide 320W by your strip's rated power per meter to find the maximum length. For example, a strip rated at 14W/m could run approximately 22.8 meters (320W / 14W per meter). Always check your strip's rated power per meter and keep the total load at or below 320W.
Is the HLG-320H-30AB weatherproof enough for a rooftop or exposed outdoor installation?
The HLG-320H-30AB is rated IP65, which protects against dust and low-pressure water jets but not submersion or heavy direct rain exposure. For a rooftop or exposed location, house it in a ventilated weatherproof enclosure. If the driver must be fully exposed, consider the IP67-rated HLG-320H-30B instead.
What is the difference between the HLG-320H-30AB and the other HLG-320H-30 variants?
All four share 320W, 30V, 10.7A core specs. The base HLG-320H-30 has fixed output and IP67 waterproof rating. The -30A adds adjustable output at IP65. The -30AB (this model) combines adjustable output and dimming at IP65. The -30B offers dimming only and retains the IP67 waterproof rating.
