AC DC Converters

AC/DC converters, also known as power adaptors, are a type of power supply used to convert alternating current (AC) into direct current (DC). They are commonly used in a variety of electrical and electronic devices, such as computers, televisions, and other household appliances. The RAC20-05SN is an example of a popular AC/DC converter. This article will discuss the application field and working principle of the RAC20-05SN.

Application Field

The RAC20-05SN is designed to provide a regulated output voltage of 5V-12V based on a constant input voltage of 110-240V AC. This makes it ideal for use in applications such as laptops, tablets, and other portable electronic devices. It is also suitable for use in intelligent household appliances, such as vacuum cleaners and air purifiers. In addition, its high efficiency and low ripple noise make it suitable for use in a variety of audio and visual devices, such as speakers, amplifiers, and projectors.

Working Principle

The RAC20-05SN works on the principle of rectification, in which the alternating current (AC) is converted into a unidirectional current (DC). This is done using a series of diodes, which are capable of conducting current in only one direction. The AC current is first drawn into the diodes and then passed through a set of capacitors, which store energy and are used to reduce the ripple noise. Finally, the DC current is passed through the output regulator, which sets and maintains the voltage level of the DC output.

The RAC20-05SN is designed to be highly reliable and highly efficient, with a nominal efficiency of 85-89%. It is also designed to operate safely, even in cases of short circuit or over-voltage. Furthermore, its ultra-low ripple noise level meets international standards. Thus, making the RAC20-05SN ideal for a variety of AC/DC conversion applications.

In conclusion, the RAC20-05SN is an efficient and reliable AC/DC converter designed to meet the needs of a variety of applications. It is suitable for use in laptops, tablets, and other portable devices, as well as intelligent household appliances, audio/visual equipment, and other electronic devices. Furthermore, its high efficiency and low ripple noise make it ideal for these applications.
