Details about the MEAN WELL HLG-120H-30AB

The MEAN WELL HLG-120H-30AB is the premier configuration in the 120W series for 30V 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 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 installation. This is paired with an external 3-in-1 dimming control cable, which supports 1-10V DC, 10V PWM signals, and external resistance for integration into smart building automation systems.

Featuring a dual-mode constant voltage and constant current output, the HLG-120H-30AB 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 lifespan of over 62,000 hours. Backed by a 7-year warranty and carrying the "Type HL" rating, it is perfectly suited for smart urban lighting and professional-grade industrial systems.
