Frequently Asked Questions

Can I use the HLG-320H-12AB to power long runs of 12V LED strip lighting in a commercial space?

Yes. The HLG-320H-12AB provides 264W at 12V with up to 22A of output current, making it well suited for extensive 12V LED strip installations in retail displays, office cove lighting, or hospitality environments. The built-in dimming input lets you integrate with a building management system for scene control.

Is the HLG-320H-12AB suitable for powering 12V LED channel letter signage?

Yes. At 264W and 12V, the HLG-320H-12AB can drive a substantial bank of 12V LED sign modules. Its IP65 water-resistant rating protects against dust and low-pressure water jets, making it appropriate for semi-sheltered outdoor sign cabinets or covered canopy locations.

Can the HLG-320H-12AB power 12V LED under-cabinet lighting across a large kitchen?

Yes. With 264W available at 12V, the HLG-320H-12AB can drive a large array of under-cabinet LED strips. The adjustable output lets you trim the voltage precisely, and the dimming input allows brightness control via a 1-10V or PWM signal from a wall dimmer.

How many meters of 12V LED strip can the HLG-320H-12AB support?

That depends on your strip's rated power per meter. The HLG-320H-12AB delivers up to 264W at 12V. For example, a strip rated at 14.4W/m would allow up to 264 / 14.4 = approximately 18.3 meters. Always check your strip's rated power per meter and keep total wattage at or below 264W.

Can the HLG-320H-12AB be mounted in a sheltered outdoor location like a building soffit?

Yes. Its IP65 water-resistant rating protects against dust ingress and low-pressure water jets from any direction. This makes it suitable for covered outdoor areas such as soffits, canopies, or ventilated electrical enclosures. For fully exposed installations with submersion risk, consider the IP67-rated HLG-320H-12B instead.

What are the differences between the HLG-320H-12, 12A, 12AB, and 12B models?

All four share the same 264W / 12V / 22A core output. The base HLG-320H-12 has no output adjustment and is IP67 waterproof. The -12A adds a built-in potentiometer for voltage and current adjustment and is IP65. The -12AB adds both the potentiometer and a 1-10V/PWM dimming input (IP65). The -12B adds the dimming input only and retains IP67 waterproof protection.
