Information about the MEAN WELL HLG-120H-C1050A
The MEAN WELL HLG-120H-C1050A is a high-performance 150W AC/DC LED driver designed for constant current operation in large-scale lighting projects. As an "A-Type" model, it features an IP65-rated aluminum housing with a built-in potentiometer, allowing installers to manually adjust the output current from 525mA to 1050mA to precisely match the LED requirements.
With an outstanding efficiency of 94% and active Power Factor Correction (PFC), the unit minimizes energy loss and thermal stress. The fanless design enables reliable operation under natural air convection, making it perfect for LED bay lighting, street lighting, and agricultural greenhouse applications. Backed by a 7-year warranty, it offers long-term stability and protection against short-circuit, over-voltage, and over-temperature conditions.
