MEANWELL PS-120-12 PS-120 Series 120W single-output switching power supplies

The MEANWELL PS-120-12 is a 120W single-output switching power supply from the PS-120 series, designed to convert AC input voltage into a stable 12V DC output. Here is a detailed introduction:

Features

Wide input voltage range: Able to operate at an AC input voltage of 90V to 264V, adapting to grid voltage fluctuations in different regions.

High efficiency: The use of advanced circuit design and power devices achieves high conversion efficiency and reduces energy loss.

Multiple protection functions: With short-circuit protection, overload protection and overvoltage protection, it can effectively protect the safety of power supply and load equipment.

Low ripple and noise: The output voltage ripple and noise are low, providing a stable and pure power supply for the load.

Natural air cooling: Heat dissipation is carried out by natural air cooling, without the need for additional cooling fans, reducing operating noise and maintenance costs.

Full load aging test: Each power supply undergoes a full load aging test before leaving the factory to ensure the quality and reliability of the product.
