Frequently Asked Questions
Can I use the HLG-480H-48AB to power a large 48V LED strip installation with dimming?
Yes. The HLG-480H-48AB delivers 480W at 48V and includes both an output adjustment potentiometer and a 1-10V/PWM dimming input. This makes it well suited for lengthy 48V LED strip runs in commercial or architectural projects where brightness control is required.
Is the HLG-480H-48AB suitable for powering 48V LED signage with brightness scheduling?
Yes. With 480W of output at 48V and built-in dimming capability, this driver can handle large channel letter signs or illuminated sign cabinets running on 48V LED modules. The dimming input allows connection to a timer or automation controller for day/night brightness scheduling.
Can the HLG-480H-48AB drive 48V LED high-bay or warehouse lighting?
Yes. At 480W and 10A of output current, the HLG-480H-48AB can power high-output 48V LED fixtures used in warehouses or industrial spaces. The adjustable output lets you fine-tune voltage to match your fixture string, and the dimming input supports occupancy-based or daylight-harvesting dimming.
How many meters of 48V LED strip can the HLG-480H-48AB support?
That depends on the strip's rated power per meter. The HLG-480H-48AB supplies up to 480W at 48V. For example, a strip rated at 20W/m could run up to 24 meters (480W / 20W per meter = 24m). Always check your strip's rated power per meter and keep total load at or below 480W.
Can the HLG-480H-48AB be mounted in a covered outdoor location?
Yes. Its IP65 rating protects against dust ingress and low-pressure water jets, so it is suitable for covered patios, soffits, or ventilated outdoor enclosures. For fully exposed or submersible installations, consider the IP67-rated HLG-480H-48B instead.
What are the differences between the HLG-480H-48, 48A, 48AB, and 48B?
All four share the same 480W / 48V / 10A core specs and aluminium casing. The base HLG-480H-48 has no output adjustment or dimming and is IP67 waterproof. The -48A adds an output adjustment potentiometer (IP65). The -48AB adds both adjustment and 1-10V/PWM dimming (IP65). The -48B provides dimming input only and retains IP67 waterproofing.
