Information about the MEAN WELL HLG-480H-54A
The MEAN WELL HLG-480H-54A is a premium 480W LED driver designed to meet the rigorous demands of industrial-grade lighting solutions. This unit stands out with its dual-mode operation, functioning seamlessly in both Constant Voltage and Constant Current modes. The "A-Type" designation is particularly valuable for specialized setups, as it features built-in potentiometers that allow for manual fine-tuning of the output voltage (45.9 – 56.7 V) and current levels (4.4 – 8.9 A). This manual adjustability ensures that users can optimize performance for specific LED configurations, compensating for voltage drops or tailoring current to specific thermal requirements.
Beyond its electrical performance, the HLG-480H-54A is engineered for survival in harsh environments. Its rugged metal housing is IP65 rated, providing robust protection against dust and moisture, making it ideal for high-mast lighting, greenhouse cultivation, and outdoor stadium applications. Operating at an industry-leading efficiency of up to 95.5%, the driver minimizes energy waste and heat generation, enabling a reliable fanless design that works at case temperatures up to +90°C. With a projected lifetime exceeding 62,000 hours and a comprehensive 7-year manufacturer warranty, it represents a top-tier investment for long-term infrastructure projects.
