AC DC Converters

AC to DC converters are an important component of any electronic device, providing a reliable and efficient means of converting alternating current (AC) power into direct current (DC) power. AC DC converters, such as the RAC20-05SB, are designed to meet the exacting power requirements of the modern electronics industry, and are capable of providing clean, regulated DC power with minimal loss. In this article, we will take a closer look at the RAC20-05SB application field and working principle, and discuss how this versatile converter can be used for a variety of applications.

Application Field

The RAC20-05SB is a fully featured AC DC converter, able to provide output power up to 10W. This makes it suitable for a wide range of applications, from consumer electronics and automotive to industrial and medical. Its input voltage range is 90-264VAC, making it suitable for use across a wide variety of different AC power networks. It also has a wide temperature range of -40 to +85°C, making it an ideal choice for both indoor and outdoor applications.

Working Principle

At its most basic, the RAC20-05SB is a switching type DC power supply, using a switching transistor to convert an alternating voltage to a regulated direct voltage. The switching transistor works like a switch, alternating rapidly between two states: On and Off. When the switch is “on”, power is supplied to a primary coil, forming a magnetic field. This magnetic field is then “fed” into a secondary coil, inducing a current in it. This induced current is then rectified and regulated, forming the desired DC power output.

Advantages

As a switching converter, the RAC20-05SB has several distinct advantages over traditional linear transformers. Foremost among these is its efficiency – switching converters are significantly more efficient than linear transformers, converting up to 97% of energy input into usable power output, as opposed to less than 60% for linear transformers. This increased efficiency leads to significant reductions in energy costs, as well as improved device longevity. The RAC20-05SB is also significantly lighter and smaller than traditional AC DC converters. As a result, it can easily be used in portable and compact designs. Finally, the RAC20-05SB has a comprehensive range of protections, including over-voltage, over-current, overload, and short-circuit protections, making it suitable for a variety of different applications and ensuring a safe and stable power supply.

Conclusion

The RAC20-05SB provides a reliable and efficient means of converting AC power into DC power, making it suitable for a variety of applications. Its switching technology ensures a high degree of efficiency, and its wide input voltage range and extensive protections make it a suitable choice for both indoor and outdoor environments. The RAC20-05SB is an excellent choice for any electronic device that requires a stable and reliable power supply.
