DC-DC converters are power converters that convert one DC power supply to another. Likewise, the REC3-0509SRW/H/B/M converters are part of this same series and are capable of operating in a variety of power conditions and environments. In this article, we will discuss the application field of the REC3-0509SRW/H/B/M converters as well as its working principle.

Application field of the REC3-0509SRW/H/B/M converters

These converters are mainly suitable for usage in power distribution and transmission systems that need to adjust the power voltage to meet different industrial standards. This makes them perfect for connecting loads that require different voltage levels for operation. Furthermore, these converters are also beneficial in various fields such as telecommunications, medical equipments, defense, and even aviation and space exploration technology.

In a more specific context, the REC3-0509SRW/H/B/M converters possess a wide input voltage range of around 7V to 54V with up to 800W for their base model and up to 600W for the H-model. This makes them suitable for connection to a variety of power sources. Moreover, they possess a galvanic isolation resistance of up to 1500V, which makes them suitable for applications that require high voltage insulation.

Working principle of the REC3-0509SRW/H/B/M converters

The working principle of the REC3-0509SRW/H/B/M converters is based on the boost switching converter, which is a different topology from the standard Power Factor Correction (PFC) converter. In the boost converter, an inductor is connected to the input along with a diode and a capacitor. During the ON time, the inductor accumulates energy from the input, while in the OFF time, the energy is released to the output via a diode. This enables the converter to change the voltage and current level.

The diode and inductor together form a LC filter that suppresses the input current ripple. The capacitor on the output is used to filter the output voltage ripple. In addition, the highfrequency switching also helps reduce the current ripple at the input. As a result, the overall system achieves high power density with low noise, enabling it to handle heavy loads in harsh power conditions.

Conclusion

In conclusion, the REC3-0509SRW/H/B/M converters are versatile DC-DC power converters that are suitable for a variety of applications ranging from telecommunications to medical use. As discussed in this article, these converters possess a wide input range that makes them suitable for connection to a variety of power sources. Moreover, the working principle based on a switching boost converter enables them to handle heavy loads with low noise in various power conditions.
