Information about the MEAN WELL HLG-320H-36AB
The MEAN WELL HLG-320H-36AB represents the peak of versatility in the HLG family, offering a "best of both worlds" approach for professional lighting designers. As an AB-Type model, it features dual-control capability: technicians can manually fine-tune the output voltage and current levels via internal potentiometers for hardware-level calibration, while the integrated 3-in-1 dimming interface (0-10VDC, 10V PWM, or resistance) allows for automated, real-time light management. This hybrid design ensures the driver can adapt to nearly any high-power LED array architecture, providing stability in both Constant Voltage (CV) and Constant Current (CC) modes. Encased in a ruggedized metal housing with an IP65 rating, it is engineered for extreme durability in harsh environments, such as LED high-bay lighting, urban infrastructure, and greenhouse lighting systems. With an impressive efficiency of 94% and built-in active PFC, the unit operates with minimal energy waste and thermal stress, enabling a completely fanless operation even at temperatures up to +90 °C. Supported by an industry-leading 7-year warranty and a typical lifetime of over 62,000 hours, the HLG-320H-36AB is the definitive choice for mission-critical power delivery.
