DC DC Converters

DC DC converters, or direct current to direct current converters, are electronic components used to convert direct-current (DC) electrical power from one voltage to another, providing regulated outputs for power supplies, radios, computers, and other sophisticated devices. The REC3-2415DRW/H4/A/SMD/CTRL is a DC DC converter specifically designed to provide reliable and efficient operation in high voltage environments.

Device Specifications

The REC3-2415DRW/H4/A/SMD/CTRL is a non-isolated step-down DC DC converter with a continuous output power of 15 W over a wide input voltage range of 4.5-24 V DC and adjustable output voltage of up to 3 V DC. It has a high efficiency of up to 92% and a wide operating temperature range of -40 to +90°C, providing a reliable and long-lasting operation of the device under harsh atmospheric conditions or extreme temperatures. It complies with the internationally recognized safety standards of the RoHS, UL, and TUV requirements, providing a safe and secure operation of the device.

Application Field

Owing to its features and specifications, the REC3-2415DRW/H4/A/SMD/CTRL is suitable for a variety of applications in telecommunications, automotive, industrial, medical, and consumer devices. It can be used as an AC-to-DC voltage regulator for industrial automation devices, for example, as a separate power supply for machine controllers or for cellular repeaters. It is also commonly used in industrial automation, IoT and medical monitoring systems, for powering alarms and sirens, LED lighting systems, and electric instruments.

Working Principle

The REC3-2415DRW/H4/A/SMD/CTRL converter operates on the PFM (pulse frequency modulation) working principle, in which the pulse frequency is modulated as per the output voltage requirements. The output DC voltage is generated by converting the input AC or DC voltage into a high frequency pulse train with the help of the power switching transistor. This pulse train is then rectified and filtered, and then fed to the transformer. The transformer reduces the voltage and delivers the output voltage at the required level. The output voltage can be adjusted by varying the frequency of the pulse train.

Conclusion

The REC3-2415DRW/H4/A/SMD/CTRL DC DC converter is a high-efficiency device designed to meet the needs of demanding applications in harsh environments. It is widely used in a variety of industrial applications, telecommunications, and medical monitoring systems. The device works on the Pulse Frequency Modulation (PFM) working principle, in which the pulse frequency is variably modulated in order to obtain the required output voltage.
