PSAA20R-240-R-CR4 is an AC/DC desktop, wall adapter that is used for electronics appliances. It has an input voltage range of 100 to 240 volts and an operating temperature range of -10 to 70 degrees Celsius. This wall adapter has a 5.5mm x 2.1mm plug with a voltage rating of 20 volts and a maximum current rating of 1.2A. This output voltage can be adjusted by the user, by controlling a voltage switch on the adapter itself.
Overview of the PSAA20R-240-R-CR4
The PSAA20R-240-R-CR4 is a good choice for electronics appliances when it comes to urban usage because it is highly efficient in terms of energy consumption. It is equipped with overvoltage protection, overheating protection and short circuit protection. This wall adapter also features overcurrent protection to ensure safety and stability. All these features make the adapter perfect for a range of applications including computers, routers and sound systems.Working Principle
The PSAA20R-240-R-CR4 wall adapter operates on the principle of switching to a frequency that is close to the required voltage. It has a pair of transistors connected in series with the positive and negative outputs. An oscillator controls the transistors to switch on and off electrically. This oscillator produces a signal that is applied to the base of the transistors which, when the signal is pulsed, causes the transistors to switch. This switching action modulates the electrical signal which then passes through a diode bridge. The output of this bridge is then rectified and then fed to a filter. The filtered signal then passes through a voltage regulator which produces an output voltage that is regulated and suitable for the attached device.Safety Features
The PSAA20R-240-R-CR4 is well equipped with safety features that protect the device against overvoltage and overheating. It has an in-built overcurrent protection circuit which prevents burn out of the transistors and ensures protection of the electrical equipment in case of unexpected current overload. Furthermore, this wall adapter has an in-built short-circuit protection circuit which helps in prevention of any overload situation or unexpected voltage drops.Conclusion
The PSAA20R-240-R-CR4 wall adapter is a highly efficient, reliable and safe for a wide range of applications. It has an adjustable output voltage which means it can be used for any number of electronic devices. The wall adapter is also equipped with safety features like overvoltage protection, overheating protection, short circuit protection and overcurrent protection, making it a great choice for any urban setting.The specific data is subject to PDF, and the above content is for reference
