Information about the MEAN WELL HLG-185H-48B

The MEAN WELL HLG-185H-48B is a high-performance 185W AC/DC LED driver specifically engineered for advanced lighting control and industrial-grade durability. This "B-Type" model is distinguished by its versatile 3-in-1 dimming interface, allowing for seamless adjustment of the output constant current level via 1-10VDC, a 10V PWM signal, or external resistance. Built with a rugged, fully potted metal enclosure rated at IP67, the HLG-185H-48B is completely protected against dust and water immersion, making it a premier choice for harsh environment applications such as high-bay industrial lighting, outdoor floodlights, and horticultural LED systems. It features a unique dual-mode output, enabling efficient operation in both Constant Voltage and Constant Current regions. Boasting a peak efficiency of 94% and a fanless design that operates reliably between -40 °C and +90 °C, this driver minimizes thermal stress and energy loss. With a typical life expectancy exceeding 62,000 hours and an industry-leading 7-year manufacturer warranty, it provides an exceptionally reliable and long-lasting power solution for professional infrastructure and architectural projects.
