Frequently Asked Questions

Can I use the HLG-320H-24A to fine-tune the voltage for a 24V LED lighting installation?

Yes. The HLG-320H-24A includes a built-in potentiometer that lets you trim the output voltage and current. With a CC voltage range of 12-24V, you can lower the drive level to match specific LED loads without an external dimmer, which is useful for optimizing brightness or extending LED life.

Is the HLG-320H-24A suitable for powering 24V LED strips in commercial display or retail lighting?

Yes. At 320W and 24V with adjustable output, it can power long runs of 24V LED strips used in retail display cases, shelf lighting, or showroom coves. The potentiometer lets you dial in the exact brightness level needed for the display.

Can the HLG-320H-24A drive 24V LED modules for architectural accent lighting?

Yes. With 320W at 24V and adjustable output, it handles large architectural LED accent installations such as facade lighting, cove lighting, or landscape up-lighting. The ability to trim output voltage ensures precise brightness matching across different LED module brands.

How many meters of 24V LED strip can the HLG-320H-24A support?

Divide 320W by your strip's rated wattage per meter. For example, a strip drawing 20W/m allows up to 16 meters (320W / 20W per meter = 16m). Always check your strip's rated power per meter and keep total load at or below 320W for reliable operation.

Can the HLG-320H-24A be installed in a covered outdoor patio or parking structure?

Yes. Its IP65 water-resistant rating protects against dust ingress and low-pressure water jets, which is appropriate for covered outdoor areas like patios, carports, or parking garages. For locations with direct rain exposure, consider the IP67-rated HLG-320H-24 instead.

What are the differences between the HLG-320H-24, 24A, 24AB, and 24B models?

All four share the same 320W / 24V / 13.34A core specs. The base HLG-320H-24 has no adjustment or dimming and is IP67 waterproof. The -24A adds output adjustment via potentiometer and is IP65 water-resistant. The -24AB adds both adjustment and 1-10V/PWM dimming (IP65). The -24B offers dimming input only and retains IP67.
