Working Principle

The 5V 5A SMPS converts 100–240V AC mains power into a regulated 5V DC output using high-frequency switching technology.

The incoming AC voltage is first rectified and filtered into DC. This DC voltage is then switched at a high frequency through a transformer, where it is stepped down to the required voltage level. The output is then rectified, filtered, and regulated to produce a smooth and stable 5V DC supply.

An internal feedback circuit continuously monitors the output voltage and automatically adjusts the switching operation to maintain constant output voltage despite variations in load or input voltage. Built-in protection circuits monitor abnormal operating conditions and automatically protect the power supply and connected equipment.
