Details about the MEAN WELL HLG-120H-24AB
The MEAN WELL HLG-120H-24AB is the premier 120W LED driver for applications requiring absolute control. As an "AB-Type" hybrid model, it is engineered for projects that demand both a baseline hardware calibration and ongoing dynamic electronic control, making it the most versatile unit in the 24V product line.
The unit features a dual-control architecture. It is equipped with built-in internal potentiometers protected by rubber seals, allowing for the manual fine-tuning of output voltage and current levels during installation. Simultaneously, it provides an external 3-in-1 dimming control wire, supporting 1-10V DC, 10V PWM, and resistance signals for integration into smart building automation systems.
Encased in a rugged IP65-rated metal housing, the HLG-120H-24AB ensures excellent thermal management and protection against dust and moisture. Its fanless design relies on natural air convection, enabling silent operation and a typical life expectancy exceeding 62,000 hours. Backed by an industry-leading 7-year warranty and a "Type HL" rating for hazardous locations, it is a top-tier choice for smart urban lighting, industrial high-bay luminaires, and professional horticultural systems.
