Adapters for AC-DC desktop, wall and mobile applications are numerous and provide a vital service for those who require them. They are commonly used for powering computers, phones, laptops and other electronic devices. The PSAA20R-120-R-CN3 adapter is one such adapter and is extremely reliable. Here, we will discuss the application field and working principle of this adapter.

The main application field for the PSAA20R-120-R-CN3 adapter is providing an output voltage of 3.3V but is also capable of providing a maximum output current of 2.0A. The adapter is also suitable for wall-mounted applications, being equipped with both screw terminals and spade terminals for secure mountings. Additionally, it is suitable for use with DC power supplies and as a mobile power bank for charging a handheld device or powering small circuits.

Now let’s take a look at the PSAA20R-120-R-CN3 adapter’s working principle. It’s the primary component of an AC to DC conversion system. It works by supplying an AC voltage of 120V to a power transformer with a step-down function, reducing the voltage from 120V to 3.3V. This reduced voltage is then rectified by a rectifier, which further smoothens the signal for stable and accurate power supply. The output of the rectifier is then filtered by a capacitor, which filters the ripple in the output voltage and prevents any interference in the signal.

The output of the filter is then passed on to the regulated output of the adapter. The voltage regulator is used to regulate the output voltage and current of the adapter depending on the input voltage given to it. The voltage regulator also prevents any unwanted fluctuations that may occur due to voltage fluctuations in the external input voltage. Thus, the PSAA20R-120-R-CN3 adapter can be used in applications requiring a reliable voltage and current.

In summary, the PSAA20R-120-R-CN3 adapter is suitable for both desktop andwall-mounted applications, providing an output voltage of 3.3V with a maximum output current of 2.0A. It is also equipped with a voltage regulator that ensures reliable and accurate output voltage and current regardless of external voltage fluctuations. With its reliable performance and wide range of applications, the PSAA20R-120-R-CN3 adapter from Fairchild is a great choice for those who need efficient and precise power conversion.
