Working Principle

The working principle of the SGA12U12-P1J AC/DC desktop wall adapter is based on the concept of switching power supply technology. This is a power supply technology that uses transistors to convert AC power into DC power in a more efficient way than linear regulators. It includes a power factor correction (PFC) circuit, which helps reduce electric noise and power distortions, and an EMI filter, which helps reduce electromagnetic interference.

The SGA12U12-P1J AC/DC desktop wall adapter is connected to an AC power source, such as a wall outlet. The incoming AC current is converted into DC current using a rectifier circuit. The primary power switch then turns on the PFC circuit, which in turn activates the EMI filter. Now, the switching IC drives the primary switch and adjusts the output to the specified voltage level. After that, the output current is filtered and regulated using output diodes and secondary filters, enabling the device to provide a stable DC output.

Conclusion

The SGA12U12-P1J AC/DC desktop wall adapter is a reliable and versatile power supply device, boasting a range of impressive features and great versatility. Its wide input voltage range, wide operating temperature range, and numerous safety features make it an ideal choice for powering desktop computers, chargers, and various other electronic devices.
