With an input voltage range from 9 to 36V, the converter can be used with a wide variety of existing power sources. It has a wide operating temperature range of -40 to +85°C, making it suitable for use in extreme temperatures. Additionally, it has an adjustable output voltage range from 24.1 to 40.8V, allowing the user to set the output to their desired voltage. Additionally, the device has a high efficiency rating, a low ripple and noise, and complies to EN standard regulations.

Applications

The QSB15048WS48 is suitable for a number of different applications. It is commonly used in industrial systems, telecommunications, automotive systems, and power supplies. In industrial systems, it is used in both indoor and outdoor settings where it provides a stable, reliable, and highly-efficient power source. It is also often used in telecommunications networks, where its low ripple and noise help reduce interference with communication signals. In automotive applications, it is used to provide the power supply necessary for vehicle operations. Finally, it is also used in power supplies to provide a constant voltage and current.

Working Principle

The QSB15048WS48 is a buck-boost DC-DC converter, meaning it is able to convert both higher and lower voltages. When the input voltage is higher than the output voltage, it operates as a step-down converter, reducing the input voltage until it is equal to the output voltage. When the input voltage is lower than the output voltage, it operates as a boost converter, increasing the input voltage until it is equal to the output voltage. It achieves this by using an internal switch connected to an inductor. When the switch is open, the inductor acts as a filter, smoothing out the current and storing energy. When the switch is closed, the inductor releases its stored energy to the load, providing a stable voltage and current.

Conclusion

The QSB15048WS48 is a versatile DC DC converter capable of providing up to 48A of current output. Its wide input voltage range, adjustable output voltage range, and operating temperature range make it suitable for a variety of different applications, including industrial systems, telecommunications, automotive systems, and power supplies. Furthermore, its buck-boost operating principle provides both the step-down and step-up function, enabling it to provide a stable and reliable output voltage regardless of the input voltage. Therefore, the QSB15048WS48 is a great choice for providing a constant DC voltage or current.
