Information on the MEAN WELL HLG-320H-48AB

The MEAN WELL HLG-320H-48AB is a high-performance 320W LED driver that offers the ultimate level of control and reliability for professional lighting infrastructure, backed by an extensive 7-year manufacturer warranty. As a hybrid AB-Type model, it uniquely integrates both internal potentiometers for manual voltage and current adjustment and a 3-in-1 dimming channel compatible with 0-10VDC, 10V PWM signals, or resistance. This combination allows engineers to set a precise maximum output threshold while maintaining full external dimming control, making it ideal for advanced LED street lighting, high-bay industrial lamps, and horticultural greenhouse systems. The unit features a peak efficiency of 95% and is housed in a rugged IP65-rated metal casing, enabling fanless operation through free air convection even in extreme climates ranging from -40 °C to +90 °C. With its built-in active PFC function and a typical lifetime exceeding 62,000 hours, the HLG-320H-48AB is engineered to minimize maintenance costs and energy consumption in large-scale, mission-critical installations.
