Information on the MEAN WELL HLG-320H-24B
The MEAN WELL HLG-320H-24B is a high-performance LED driver specifically engineered for applications requiring advanced light intensity management through its versatile 3-in-1 dimming interface. Unlike standard models, the B-Type variant features a dedicated dimming cable that supports 0-10VDC, 10V PWM signals, or resistance-based control, offering seamless integration into automated building systems and professional dimming setups. This driver utilizes a dual-mode design, maintaining stable operation in both Constant Voltage (CV) and Constant Current (CC) regions to accommodate various LED array requirements. Built for the most demanding environments, the HLG-320H-24B is housed in a robust aluminum casing and is fully potted to achieve an IP67 ingress protection rating, making it waterproof and suitable for outdoor or high-humidity industrial sites. Its superior 94% efficiency and active PFC function ensure minimal heat generation, allowing for a reliable fanless operation even at elevated temperatures up to +90 °C. With a 7-year manufacturer warranty and a typical lifetime of over 62,000 hours, this power supply is a premier choice for high-bay lighting, street illumination, and large-scale signage where durability and precision control are paramount.
