AC/DC converters are invaluable devices which make it possible for electric currents to transfer from AC to DC, a feature which has allowed for the creation of a wide range of electrical and electronic products and models. One such converter is the TB110S48K, a non-isolated topology DC/DC switch mode converter which can accept 40-60VAC input voltage and can provide up to 12V DC output. In this article, we\'re going to explore the application field and working principle of the TB110S48K.

Application Field

The TB110S48K has a wide range of uses and is a great choice for many applications which require AC to DC conversion. It has a wide input range of 40 VAC to 60 VAC and offers a high voltage efficiency of up to 96%. The input voltage is internally limited to 28VAC to stops any direct currents. As a practical example, TB110S48K could be used for powering remote monitoring Instrumenation without an isolator, or it could be used in a constant voltage/constant current driver applications.

Working Principle

The TB110S48K uses a synchronous rectification and a non-isolated topology DC/DC switch mode converter circuit to convert AC to DC. The circuit consists of a rectifier, controller, transformer, switches, and output circuitry. The rectifier converts the AC inputs to three phase DC inputs which are then provided to the controller. The controller then controls the switching of the switches, providing a constant output, depending on the needs of the application. The transformer and output circuitry provide the power to the output DC voltage.

The TB110S48K features closed cycle control with input current and short circuit protection, as well as input and output overvoltage protection. In addition, the converter has a wide temperature range from -25°C to 85°C and can operate with a wide line range from ±5%. The efficiency of the TB110S48K is up to 96%, which provides the user with a reliable and efficient power supply.

Conclusion

The TB110S48K is a non-isolated topology AC/DC converter which can accept 40-60VAC input voltage and can provide up to 12V DC output. It is a great choice for many applications which require AC to DC conversion and features closed cycle control with input current and short circuit protection, as well as input and output overvoltage protection. In addition, it has a wide efficiency range of up to 96%, making it a reliable and efficient solution.
