Information about the MEAN WELL HLG-320H-36B
The MEAN WELL HLG-320H-36B is a high-performance 320W LED driver specifically designed for professional applications requiring advanced brightness control. As a B-Type variant, it is equipped with a sophisticated 3-in-1 dimming function, allowing users to modulate light output via 0-10VDC, 10V PWM signals, or resistance through a dedicated control cable. This feature makes it a perfect fit for modern smart lighting networks and automated industrial environments. The driver utilizes a dual-mode output, ensuring maximum stability in both Constant Voltage (CV) and Constant Current (CC) regions, providing immense flexibility for different LED array architectures. Housed in a durable metal enclosure and fully potted to achieve an IP67 rating, it is engineered for long-term use in harsh outdoor conditions, such as LED street lighting, parking lot illumination, and high-bay industrial setups. Its superior 94% efficiency and active PFC function significantly reduce thermal stress, enabling a completely fanless operation at case temperatures reaching up to +90 °C. With a typical lifetime of over 62,000 hours and an industry-leading 7-year warranty, the HLG-320H-36B represents a premier choice for mission-critical power delivery.
