Frequently Asked Questions

Can I use the HLG-480H-24AB to power a large 24V LED strip installation with brightness control?

Yes. The HLG-480H-24AB delivers 480W at 24V (20A), which is enough for extensive LED strip runs. It includes both output voltage/current adjustment and 1-10V/PWM dimming, so you can fine-tune brightness from a wall dimmer or automation controller. Its IP65 rating makes it suitable for sheltered outdoor or indoor installations.

Is the HLG-480H-24AB suitable for powering 24V LED signage on a storefront?

Yes. With 480W of output at 24V, it can drive high-power LED sign modules across large channel-letter or cabinet signs. The adjustable output lets you dial in the exact voltage and current your modules need within the 12-24V constant-current range. The built-in dimming input allows automated day/night brightness scheduling.

Can the HLG-480H-24AB drive 24V LED flood lights for architectural facade lighting?

Yes, as long as the total load stays at or below 480W. The HLG-480H-24AB supports dimming via 1-10V, PWM, or resistance input, which is useful for dynamic facade lighting scenes. Its wide operating temperature range of -40°C to +90°C handles year-round outdoor conditions, though the IP65 rating means it should be mounted in a sheltered location away from direct water jets.

How many meters of 24V LED strip can the HLG-480H-24AB power?

Divide 480W by your strip's rated wattage per meter. For example, a 24V strip rated at 14.4W/m would allow up to 33 meters (480W / 14.4W per meter = 33.3m). A higher-density strip at 20W/m would allow 24 meters. Always check your strip's rated power per meter and keep total draw at or below 480W.

Can the HLG-480H-24AB be mounted outdoors in a location exposed to rain?

The HLG-480H-24AB is rated IP65, which protects against low-pressure water jets and dust ingress, but not submersion or prolonged heavy rain exposure. It is best suited for covered outdoor areas such as soffits, canopies, or weatherproof enclosures. For fully exposed outdoor mounting, consider the IP67-rated HLG-480H-24B instead.

What are the differences between the HLG-480H-24, 24A, 24AB, and 24B models?

All four share the same 480W / 24V / 20A core specs with a CC range of 12-24V. The base HLG-480H-24 has fixed output and IP67 waterproofing. The -24A adds output voltage/current adjustment via built-in potentiometer (IP65). The -24AB adds both adjustment and 1-10V/PWM dimming (IP65). The -24B offers dimming input only and retains IP67 waterproofing.
