Information about MEAN WELL HLG-320H-C1050A

The MEAN WELL HLG-320H-C1050A is a high-wattage constant current LED driver engineered for maximum durability and performance in demanding industrial lighting environments. This A-Type variant is distinguished by its built-in internal potentiometer, which allows for manual adjustment of the output current level, providing lighting designers with the flexibility to fine-tune brightness and power consumption directly at the source. Boasting an exceptional efficiency of up to 94%, the driver operates with minimal heat generation, supported by a ruggedized metal housing designed for optimal thermal dissipation. Its IP65 ingress protection rating ensures the internal electronics are shielded from dust and moisture, making it a reliable solution for high-bay lighting, outdoor floodlights, and large-scale greenhouse systems. With a typical life expectancy of over 62,000 hours and the ability to function in extreme temperatures from -40°C to +85°C, it offers unmatched reliability. The HLG-320H-C1050A also features active PFC and is classified as Type HL for use in hazardous locations, all backed by an industry-leading 7-year manufacturer warranty for total long-term investment security.
