DC DC Converters

DC-DC converters are devices that can transform a DC voltage to another, lower or higher, DC voltage. The R-551.2DA converter is a type of DC-DC converter that is specifically designed and used for power conditioning and conversion. It lets user access power from a battery source has a higher voltage than the one needed for the electronic device or appliance.

R-551.2DA Application Field and Working Principle

The R-551.2DA converter is mainly used in industrial applications, telecommunication systems, and IoT (Internet of Things) applications. It can also be used to provide power to a low voltage load like an LED light, a DC motor, or a solar panel. This converter can handle input voltages range from 8 volts to 16 volts and deliver outputs from 7 volts to 15 volts, at up to 10 watts.The working principle of the R-551.2DA converter is based on the switched-mode power supply technology. This type of converter operates in a switching mode that involves switching the voltage on and off, at a very high frequency, to achieve the desired output voltage.The converter has an interlink system that consists of a series of transistors, diodes, inductors, and capacitors. When the high input voltage is applied, the transistors activate and switch the internal circuitry to charge up the inductor. The voltage stored in the inductor is then used to charge up the output capacitors which provide the output power at the right voltage.As the input voltage drops, the number of transistors reduce and so does the current delivered to the inductor. This reduces the amount of voltage available to charge up the output capacitors. As the input voltage returns to normal levels, the transistors again switch on and the current and output voltage return to their nominal values, allowing the output feed to remain constant.

Advantages of the R-551.2DA

One advantage of the R-551.2DA is its high efficiency which is up to 96%, compared to much lower efficiency of linear DC power supplies. Since the R-551.2DA converter uses high frequency switching, it exhibits very low levels of electromagnetic radiation, making it suitable for electromagnetically sensitive applications.Moreover, it features current limiting and over-voltage protection, with adjustable limits, to provide voltage regulation, as well as short circuit protection and thermal protection for overload conditions. The adjustable limits makes it easier to use for various input voltage levels.Finally, the R-551.2DA converter has a universal input voltage and can be used with both AC and DC power sources. This makes it ideal for use in a wide range of industrial and portable power supply applications.

Conclusion

The R-551.2DA DC-DC converter is a versatile and reliable power supply solution that offers many advantages compared to traditional linear DC power supplies. It is suitable for a wide range of applications, from industrial applications to small, portable electronics, thanks to its universal input voltage. Moreover, its high efficiency, low electromagnetic radiation emissions and adjustable limits of current limiting and over-voltage protection makes it ideal for sensitive devices or equipment.
