Working Principle of MW173KB1503F01

The MW173KB1503F01 AC/DC desktop/wall adapter works by converting the AC power source from a universal AC input of 90-264V/50-60Hz to DC power. Its internal components include an isolation transformer, a rectifier, a filter circuit, a regulator, and a Galvanic Isolation Circuit. The transformer acts as an inductor which changes the AC voltage into a lower AC voltage suitable for the rectifier. The filter circuit blocks the high frequency, and the regulator ensures a steady output.

The Galvanic Isolation Circuit is a critical safety feature in the MW173KB1503F01. This circuit prevents any unintentional electrical connections between the input and output of the adapter, providing a means of short-circuit protection. The Galvanic Isolation Circuit also provides improved noise reduction, reducing interference from nearby electronics.

The MW173KB1503F01 accepts an input voltage from 90-264V/50-60Hz and provides regulated outputs of 12V,5V and 3V for applications such as IT products, small household appliances, automotive electronics, and industrial control. It is designed to be compliant with telecom, safety, EMC, and low-voltage standards.
