(Case): −40 °C to +80 °C IP Rating: IP65 Typical Lifetime: > 62,000 hours Manufacturer Warranty: 7 Years Information about the MEAN WELL HLG-120H-42AB The MEAN WELL HLG-120H-42AB is the premier configuration in the 120W series for 42V applications, offering a unique hybrid of manual and electronic control features. Designed for sophisticated lighting architectures, this "AB-Type" model provides installers with the ultimate toolset for both initial hardware calibration and ongoing dynamic operation. The core advantage of this unit is its comprehensive adjustment architecture. It features built-in potentiometers located under protective rubber seals, allowing for the manual fine-tuning of output voltage and current levels during setup. This is paired with an external 3-in-1 dimming control cable, supporting 1-10V DC, 10V PWM signals, and external resistance. This combination allows for a high degree of precision, enabling users to set a performance baseline and adjust light output as needed via building automation systems. Featuring a dual-mode constant voltage and constant current output, the HLG-120H-42AB ensures high stability across diverse LED configurations. The IP65-rated aluminum housing facilitates efficient thermal management and provides robust protection against environmental ingress. With 93% efficiency and active PFC, the driver meets stringent energy requirements while maintaining a typical lifespan of over 62,000 hours. Backed by a 7-year warranty, it is a top-tier choice for smart urban lighting and professional-grade industrial systems.
