Information about the MEAN WELL HLG-320H-42
The MEAN WELL HLG-320H-42 is a high-performance 320W AC/DC LED driver, specifically engineered to meet the rigorous demands of industrial and outdoor lighting. A defining feature of this series is its dual-mode output, which allows the driver to operate seamlessly in both Constant Voltage (CV) and Constant Current (CC) regions, providing engineers with significant flexibility for various LED array configurations. Housed in a rugged aluminum enclosure and fully potted to meet IP67 standards, it is effectively protected against dust and water, making it ideal for LED street lighting, parking lot illumination, and high-bay industrial setups. The unit features a highly advanced circuit design with built-in active PFC and an efficiency of 94%, which minimizes heat dissipation and maximizes energy savings. This thermal efficiency enables a fanless design that operates silently under free air convection, even at extreme case temperatures up to +90 °C. With a typical lifetime of over 62,000 hours and backed by an industry-leading 7-year warranty, the HLG-320H-42 remains a top-tier choice for mission-critical lighting and greenhouse lighting systems where maintenance-free longevity is paramount.
