TEX 120-124

AC DC Converters – The TEX 120-124 Application Field and Working Principle

The TEX 120-124 series of AC DC converters are devices designed to convert electricity from alternating current (AC) to direct current (DC). It is used for a variety of applications, ranging from industrial processes and home appliances to computer and telecommunication equipment. The core of the converter is the transformer, which is responsible for converting the incoming AC voltage into an intermediate voltage that is suitable for the desired DC output.The TEX 120-124 is a transformer-based AC DC converter, based on the Flyback topology. It includes an input rectifying circuit, a main switching element, a control section, an output voltage regulator, and a output filtering section. The input rectifier converts the AC mains to a DC voltage, which is then sent to the main switching transistor. The pulse-width modulation (PWM) control section of the converter is responsible for regulating the output voltage, by varying the duty-cycle of the switching transistor. This duty-cycle is in turn determined by the reference voltage generated from the output voltage regulator. The output filter section is used to smooth out any residual AC ripple, ensuring a steady and clean output voltage.The TEX 120-124 is designed to provide a reliable and accurate DC output voltage from an unsafe AC mains. It features an overvoltage protection circuit, which will protect the converter and the connected load from potentially dangerous AC voltage fluctuations. Additionally, it has a low standby power consumption and an extended temperature range, making it suitable for a wide range of applications. The TEX 120-124 AC DC converters can be used in a variety of applications, such as industrial automation and control, home appliances, computer systems, electronic instruments, security systems, telecommunications, and many more. It is also suitable for use in hazardous environments, such as mines and shipyards.The TEX 120-124 series of AC DC converters offer a cost-effective and reliable solution for meeting the power requirements of a wide range of commercial and industrial applications. They are highly reliable, easy to maintain, and feature a wide range of safeguards ensuring a safe and efficient operation.
