OWA-90U-30-P1M Application Field and Working Principle

OWA-90U-30-P1M belongs to the AC-DC desktop, wall adapters category which is used to transfer electric energy from the AC supply to a DC voltage output. OWA-90U-30-P1M is suitable for various electronic products, such as digital cameras, lighting and multimedia televisions, players and more. Its working principle is to use a rectifier circuit to convert AC voltage into DC voltage.

The OWA-90U-30-P1M adapter is composed of a core component, a rectifier bridge, a filter capacitor, a voltage regulator and other components, as well as and a PFC switch. The core component of the OWA-90U-30-P1M adapter is an AC power supply, which has a power range of 0-90W. It is used to convert AC voltage into a DC voltage, and its voltage adjustment range is 0.3-1M. In order to increase the stability of the electric energy, a rectifier bridge is used to convert AC voltage into DC voltage. The rectifier bridge acts as a one-way valve, and the two ends of the rectifier bridge connected to the core component are output with a stepping voltage of 220V.

At the output end of the rectifier bridge, PFC switch is also installed, which makes the DC voltage generated by the rectifier bridge meet the requirements of the European Commission’s PFC regulations. The filter capacitor is designed to store electricity and filter out AC components. Generally, the filter capacitor is connected in parallel with the output terminal of the rectifier bridge.

Finally, a voltage regulator is installed to adjust the output voltage of the adapter. The voltage regulator is the most critical component of the adapter, and its function is to keep the output voltage of the adapter stable despite the fluctuation of the input voltage. The voltage regulator can adjust the output voltage of the adapter in a range of 0.3-1M, ensuring the stability of the output voltage.

In summary, OWA-90U-30-P1M AC-DC desktop, wall adapter converts AC voltage into DC voltage, and its working principle involves core components, rectifier bridge, filter capacitor, voltage regulator and other components. The core component is an AC power supply with a power range of 0-90W. Rectifier bridge is used to convert AC voltage into DC voltage. The filter capacitor acts to store electricity and filter out AC components, and the voltage regulator adjusts the output voltage of the adapter from 0.3-1M, ensuring the stability of the output voltage.
