Information about the MEAN WELL HLG-320H-36

The MEAN WELL HLG-320H-36 is a professional-grade 320W AC/DC LED driver engineered to provide maximum stability for high-power lighting systems. Its primary strength lies in its dual-mode output, which allows the unit to operate seamlessly in both Constant Voltage (CV) and Constant Current (CC) regions, providing engineers with incredible design flexibility. Encased in a rugged metal housing and fully potted to meet IP67 ingress protection standards, this driver is perfectly suited for harsh outdoor environments and high-bay industrial lighting. The advanced circuitry includes an active PFC function and achieves a superior efficiency of 94%, which minimizes internal heat generation. This high thermal performance enables a fanless design that functions reliably via natural convection even at extreme case temperatures up to +90 °C. Whether it is used for LED street lighting, parking lot illumination, or greenhouse lighting, the HLG-320H-36 ensures long-term maintenance-free operation. Backed by a 7-year manufacturer warranty and featuring a typical lifetime exceeding 62,000 hours, it remains the industry standard for mission-critical power delivery.
