Information about the MEAN WELL HLG-120H-48AB
The MEAN WELL HLG-120H-48AB represents the ultimate flexibility in the 120W series for 48V systems. As an "AB-Type" hybrid, it combines the manual on-site adjustment capabilities of the A-series with the sophisticated remote control features of the B-series, making it a favorite for high-end industrial and architectural integration.
This model features a comprehensive control architecture. Installers can use the built-in potentiometers located under protective rubber seals to fine-tune the output voltage and set a precise current limit. Simultaneously, the driver provides an external 3-in-1 dimming cable, allowing for dynamic light regulation via 1-10V DC, 10V PWM signals, or external resistance. This dual capability ensures that a performance baseline can be established during installation while maintaining full compatibility with smart building management systems.
Operating in dual-mode constant voltage and constant current, the HLG-120H-48AB maintains 93% efficiency and features active Power Factor Correction (PFC). The IP65-rated aluminum enclosure provides excellent thermal management and protection against dust and water ingress. With a lifespan of over 62,000 hours and a 7-year manufacturer warranty, it is a top-tier choice for smart 48V urban lighting and professional horticultural applications.
