Frequently Asked Questions
Can I use the HLG-320H-12A to adjust output voltage for 12V LED strip runs that experience voltage drop?
Yes. The HLG-320H-12A includes a built-in potentiometer that lets you increase the output voltage slightly above nominal 12V to compensate for voltage drop over long LED strip runs. This helps maintain uniform brightness at the far end of the strip. The CC range of 6-12V also accommodates varied LED configurations.
Is the HLG-320H-12A suitable for powering large 12V LED signage installations with adjustable brightness?
The HLG-320H-12A delivers 264W at 12V with 22A output and a potentiometer for current and voltage adjustment. However, it does not have a dimming input — the potentiometer sets a fixed output level. If you need remote or automated brightness control, consider the HLG-320H-12AB or HLG-320H-12B instead.
Can the HLG-320H-12A drive 12V LED modules for retail display lighting?
Yes. At 264W and 12V, the HLG-320H-12A can power extensive 12V LED module arrays in retail displays, showcases, and backlit graphics. The adjustable output lets you fine-tune brightness to the display designer's specification. Its compact dimensions of 252.0 × 90.0 × 43.8 mm allow concealed mounting behind display walls.
How many watts of 12V LED fixtures can I connect to the HLG-320H-12A?
The HLG-320H-12A supplies up to 264W at 12V (22A). Your total connected 12V LED load must stay at or below 264W. For example, if you have ten 12V LED modules at 24W each, the total is 240W, which is within the driver's capacity. Always verify each module's rated wattage before connecting.
Is the HLG-320H-12A rated for damp or semi-outdoor locations?
Yes. The IP65 rating protects against dust ingress and low-pressure water jets from any direction. It is suitable for damp locations, ventilated outdoor cabinets, covered canopies, and sign boxes where direct rain is blocked. For fully exposed outdoor installations, consider the IP67-rated HLG-320H-12 or HLG-320H-12B.
What are the differences between the HLG-320H-12, 12A, 12AB, and 12B models?
All four share 264W / 12V / 22A core specs. The base HLG-320H-12 has fixed output and IP67 waterproof rating. The -12A (this model) adds output voltage/current adjustment via potentiometer (IP65). The -12AB adds both adjustment and 1-10V/PWM dimming input (IP65). The -12B provides dimming input only and retains IP67 waterproof rating.
