Working Principle

The SWI18-12-E-P5R adapter is a switched-mode power supply, which means it uses switching components to provide a high level of conversion efficiency. The device uses a full bridge rectifier to convert the incoming AC line voltage into DC voltage. A control chip then regulates the output, adjusting the frequency of the switching components to provide a constant voltage regardless of the load or input conditions.

The adapter also features an active power-factor correction circuit, which helps the device to maintain a high efficiency under varying input conditions. The active PFC circuit reduces the harmonic distortion of the mains current, reducing the impact on the electrical grid.

The SWI18-12-E-P5R adapter is designed with a built-in EMI filter, ensuring that the adapter meets the latest EMI/RFI emission requirements. The filter also reduces the impact of any unwanted EMI/RFI on the connected device.
