Frequently Asked Questions
Can I use the HLG-320H-24AB with a building automation system to dim 24V LED lighting?
Yes. The HLG-320H-24AB accepts 1-10V and PWM dimming signals, making it compatible with most building management and automation systems. At 320W and 24V with an adjustable potentiometer, you get both automated and manual brightness control for large 24V LED installations.
Is the HLG-320H-24AB a good choice for dimmable 24V LED cove or indirect lighting?
Yes. With 320W at 24V, built-in dimming, and adjustable output, it is well suited for architectural cove lighting where smooth brightness transitions and precise output tuning are important. The dimming input allows integration with scene controllers or timers.
Can the HLG-320H-24AB power a large 24V LED strip installation with scheduled dimming?
Yes. The 1-10V/PWM dimming input lets you pair with a timer or daylight sensor to reduce brightness automatically, for example dimming retail display lighting after business hours. At 320W and 24V, it supports long continuous strip runs.
How many meters of 24V LED strip can the HLG-320H-24AB drive?
The HLG-320H-24AB supplies up to 320W. Divide 320 by your strip's wattage per meter to get the maximum run length. A strip rated at 16W/m, for instance, allows up to 20 meters (320W / 16W per meter = 20m). Always check your strip's rated power per meter before sizing.
Is the HLG-320H-24AB suitable for a damp indoor environment like a commercial kitchen or wash-down area?
Yes. Its IP65 water-resistant rating protects against dust and low-pressure water jets, which is adequate for commercial kitchens, food processing areas, or car washes where splashing occurs. For full submersion or direct high-pressure wash-down, an IP67 model like the HLG-320H-24B would be more appropriate.
What is the input voltage range of the HLG-320H-24AB for international installations?
The HLG-320H-24AB accepts 90-305VAC input, covering virtually all global mains voltages from 100V (Japan) to 277V (US commercial). This wide range eliminates the need for an external step-down transformer in most international installations.
