Information about MEAN WELL HLG-320H-C1050AB

The MEAN WELL HLG-320H-C1050AB is a top-tier 315W constant current LED driver, uniquely engineered to provide maximum flexibility for high-power professional lighting systems. This hybrid AB-Type model combines two powerful control features: an internal potentiometer for manual output current calibration and an integrated 3-in-1 dimming interface (0-10V, 10V PWM, or resistance) for advanced external automation. This makes it an ideal choice for complex lighting architectures, such as stadium floodlighting, high-bay industrial luminaires, and architectural facades where precise on-site tuning and centralized control are both essential. With a high efficiency rating of 94%, the driver minimizes energy loss and operates via free air convection within a ruggedized IP65-rated metal enclosure, designed to withstand temperatures from -40°C to +85°C. Its Type HL classification ensures safety in hazardous locations, while the built-in active PFC optimizes power quality across global voltage ranges. Backed by a 7-year manufacturer warranty and a typical lifetime of over 62,000 hours, the HLG-320H-C1050AB stands as a reliable, long-term power solution for the most demanding LED applications worldwide.
