MEAN WELL HLG-120H-48A – 120W Adjustable LED Power Supply, 48V DC, 2.5A, IP65
The MEAN WELL HLG-120H-48A is a high-efficiency 120W AC/DC LED power supply designed to deliver stable and reliable power for professional LED lighting systems. Featuring adjustable output voltage and current, active Power Factor Correction (PFC) and a durable IP65-rated metal enclosure, it is suitable for industrial, commercial and outdoor lighting applications.
The power supply provides a nominal 48V DC output with a maximum current of 2.5A. Its output voltage can be adjusted between 43V and 53V, while the output current can be adjusted from 1.2A to 2.5A using built-in potentiometers. This flexibility allows the power supply to accommodate different LED lighting requirements.
With a typical efficiency of 93.5%, the HLG-120H-48A minimizes energy losses and heat generation. Its fanless design uses natural air convection for silent operation, while the robust aluminium enclosure provides effective heat dissipation and protection against dust and water ingress.
The integrated active PFC function improves power factor performance, making the unit suitable for professional lighting installations where energy efficiency and electrical performance are important.
