Here is the product introduction of the MEANWELL PS-120 series 120W single-output switching power supplies:
The PS-120 series is a group of 120 - watt single - output AC - DC switching power supplies designed by MEANWELL. These power supplies are suitable for a variety of electronic devices that require a stable DC power supply. They can convert the input AC voltage into a stable DC output voltage to meet the power needs of different equipment.
Features
Universal Input Voltage Range: It can work with an input voltage ranging from 90V to 264V AC, covering a wide range of voltage standards, which makes it adaptable to different power grids.
Multiple Protections: It has short - circuit, overload, and over - voltage protection functions to protect the power supply and connected equipment from damage.
High - Efficiency Conversion: With high - efficiency conversion circuits, it can achieve relatively high conversion efficiency, reducing energy loss.
Low Leakage Current: The leakage current is less than 0.75mA, ensuring safety and reliability in operation.
Free Air Convection Cooling: It adopts free air convection for cooling, which helps to dissipate heat effectively and maintain stable operation.
