DC DC Converters

DC-DC converters are devices used for converting direct current (DC) from one voltage level to another. They are most commonly used in applications where a voltage or current source is required that is different to the one supplied by the source. REC5-123.3SRW/H4/A/SMD-R is an example of such a converter. This article provides an overview of its application fields and the working principle behind it.

Application Fields

REC5-123.3SRW/H4/A/SMD-R is a DC-DC converter designed for the industrial market. It is a compact and highly efficient device that can be used in a variety of applications, including industrial automation, automotive, telecoms, consumer electronics and renewable energy systems. The wide input voltage range of this converter makes it suitable for use with both AC and DC sources. It can also provide up to 12A output current, making it ideal for powering larger applications.

Working Principle

The REC5-123.3SRW/H4/A/SMD-R is based on a switched-mode power supply (SMPS) design. This type of converter is able to step up or step down an input voltage to a different voltage level effectively and efficiently. The device works by switching the power on and off at a very high frequency, typically tens of kilohertz to megahertz. This switching creates a stepped voltage which is then filtered and rectified to give a stable output voltage. The controlling of the switching is done with the help of a control circuit, which uses a Pulse Width Modulation (PWM) technique. The output voltage is determined by the degree of modulation, i.e. how long the signal is kept ‘on’ for compared to the period it is ‘off’. This helps to optimize the output voltage to a level required by the load. Another important feature is the protection circuitry which prevents the converter from damage in the event of excessive current or over-voltage.

Conclusion

REC5-123.3SRW/H4/A/SMD-R is a DC-DC converter that provides efficient and reliable voltage conversion for a variety of applications. It is based on a switched-mode power supply design, with a control circuit that utilises a Pulse Width Modulation technique to regulate the output voltage. The device is also protected by a series of protection circuits. In summary, the REC5-123.3SRW/H4/A/SMD-R is an effective and versatile DC-DC converter suitable for use in a variety of industrial and consumer applications.
