Information about the MEAN WELL HLG-185H-48AB
The MEAN WELL HLG-185H-48AB represents the ultimate flexibility in the 185W HLG series by combining internal manual tuning with external intelligent dimming. As an "AB-Type" model, it empowers professional installers to fine-tune the output voltage and current levels via built-in potentiometers while simultaneously supporting a versatile 3-in-1 dimming interface compatible with 1-10VDC, PWM signals, or external resistance. This hybrid design is ideal for sophisticated LED installations that require a precise static setup alongside dynamic brightness adjustment. The durable IP65-rated metal housing ensures high resistance to dust and water, making it perfect for outdoor and industrial environments such as LED street lights, high-bay lighting, and professional greenhouse systems. Featuring dual-mode constant voltage and constant current output, the driver reaches an exceptional efficiency of 94%. Its fanless cooling design allows for reliable operation across a broad temperature range of -40 °C to +90 °C. Backed by a 7-year manufacturer warranty and a typical life expectancy of over 62,000 hours, the HLG-185H-48AB is a top-tier choice for sustainable, long-term architectural and infrastructure projects.
