The WR9QA2000USBNMEDR6B AC DC Desktop, Wall Adapters are designed to provide a steady, regulated output of direct current (DC) voltage from an alternating current (AC) source. It converts 110V AC to an output voltage of 12V DC. It is widely used in medical, audio, lighting and automotive applications.

Components

The AC DC Desktop, Wall Adapters are usually composed of the following components:

• AC input connector
• Voltage regulator
• Transformer
• Rectifier bridge
• Capacitor

Working Principle

The AC DC Desktop, Wall Adapters work in the following basic steps:

1. The AC input connector receives 110V AC.
2. The transformer steps down the voltage to a low AC voltage.
3. The rectifier bridge then rectifies the incoming AC voltage to a pulsating DC voltage.
4. The capacitor acts as a filter, smoothing the pulsating DC voltage.
5. The voltage regulator regulates the DC voltage to the desired level.
6. The output is a steady and regulated DC voltage of 12V DC.
