Information about the MEAN WELL HLG-480H-48A
The MEAN WELL HLG-480H-48A is a high-performance 480W power supply engineered for the most demanding LED lighting and industrial applications. As an A-Type model, it is equipped with integrated internal potentiometers that allow users to manually calibrate the output voltage level (40.8 ~ 50.4 V) and constant current range (5 ~ 10 A), providing tailored power delivery for specialized equipment. Its rugged metal housing and IP65 rating ensure superior protection against dust and moisture, making it an ideal choice for high-stress environments such as LED harbour lighting, stadium floodlights, and large-scale mining operations where reliability is non-negotiable.
Beyond its physical durability, the HLG-480H-48A excels with its dual-mode output design, allowing it to function seamlessly in both Constant Voltage (CV) and Constant Current (CC) modes. This versatility is complemented by an extraordinary efficiency rating of up to 95.5%, which enables the driver to operate reliably via fanless free air convection even at case temperatures reaching +90 °C. Featuring active PFC function and a comprehensive 7-year manufacturer warranty, this power supply represents a premium, long-term solution for professional lighting designers and engineers seeking maximum uptime and energy savings.
