Technical Information & Details for the MEAN WELL HLG-120H-12AB Power Supply Rated Power: 120 W Output Voltage (DC): 12 V Rated Current: 10 A Input Voltage Range: 90 – 305 V AC / 127 – 431 V DC Efficiency (typ.): 92 % Ripple & Noise (max.): 150 mVp-p Adjustability: Voltage (10.8–13.5V) and current (5–10A) via internal potentiometers Dimming Technology: 3-in-1 dimming (1–10V DC, 10V PWM signal, or resistance) Operating Temp. (Case): −40 °C to +80 °C IP Rating: IP65 Typical Lifetime: > 62,000 hours Manufacturer Warranty: 7 Years Details about the MEAN WELL HLG-120H-12AB The MEAN WELL HLG-120H-12AB is the premier configuration in the 120W series, offering a unique hybrid of manual and electronic control features. Designed for sophisticated lighting architectures, this "AB-Type" model provides installers and engineers with the ultimate toolset for both installation 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 on the rugged metal enclosure, allowing for the manual fine-tuning of output voltage and current. This is paired with an external 3-in-1 dimming control cable, which supports 1-10V DC, 10V PWM signals, and external resistance. This combination allows for a high degree of precision, enabling the user to set a performance baseline and vary the light output as needed via building automation systems. Featuring a dual-mode constant voltage and constant current output, the HLG-120H-12AB ensures high stability across diverse LED load types. The IP65-rated aluminum housing facilitates efficient thermal management and provides robust protection against environmental ingress. With 92% 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 for hazardous locations, it is perfectly suited for smart urban lighting, high-bay industrial luminaires, and professional-grade horticultural lighting systems.
