Introduction

DC-DC converters have become an essential component in modern power electronics, providing numerous capabilities such as adjustable output powers, multiple output voltages, and the ability to perform voltage regulation, all in a small package. REC3-243.3SRW/H2/A, a buck-boost DC-DC converter from Mean Well, is a versatile tool for powering a variety of applications, and is capable of providing a steady output voltage despite great variations in input voltage.

Applications

The REC3-243.3SRW/H2/A is a solid-state buck-boost DC-DC converter, capable of providing an output voltage of between 0-36V, with a maximum output current of 3A. It is designed for applications that require a regulated output voltage, such as portable electronics, laptop computers, server power supplies, and automobile, marine, and telecommunication systems. The wide range of input voltages that the converter can accept makes it suitable for powering applications in different locations across the globe. It is also equipped with a power switch to provide a safe shut down in case of an overload, making it more reliable.

Working Principle

The buck-boost converter of the REC3-243.3SRW/H2/A has two power stages: buck and boost. The buck stage reduces the input voltage and regulates it to the required output voltage, while the boost stage increases the output voltage if there is a need. The power switch for overload protection turns on or off as required.When the input voltage is higher than the output voltage, the buck stage is used. The converter draws current from the input source and converts it to regulated DC voltage using MOSFET switching. When the input voltage is lower than the output voltage, the boost stage is activated. The converter draws energy from the input source and transfers it to the output, through the inductor.

Conclusion

In conclusion, the REC3-243.3SRW/H2/A is a versatile, solid-state buck-boost DC-DC converter from Mean Well, designed for powering a variety of applications with input voltages from 160V to 500Vac and output voltages from 0-36V. Working on the principle of buck-boost conversion, it provides a steady output voltage despite great variations in input voltage. Applications of this converter include portable electronics, laptop computers, server power supplies, car, marine and telecommunication systems. It is also equipped with a power switch to provide a safe shut down in case of overload, making it more reliable.
