AC DC Converters

AC-DC converters are devices that convert alternating current (AC) to direct current (DC). They are a type of power electronics that work to provide reliable, efficient, and cost-effective power conversion solutions. AC-DC converters are commonly used in a variety of application fields and industries, such as industrial, renewable energy, aerospace, automotive, military, and medical.

CUS200M24 application field and working principle

The CUS200M24 is an AC-DC micro-module converter from Cosel USA. It features an ac-input voltage range of 85 to 264 VAC, and a maximum DC-output voltage of up to 24VDC. The CUS200M24 has been designed to be used in a variety of applications, including industrial instrumentation and control systems, medical equipment, office automation, telecommunication, and many more. The CUS200M24 provides high efficiency, low power loss and no-load power consumption, as well as overload, short circuit, over current, over voltage, and over temperature protections.

The CUS200M24 provides a wide range of operating functions, with a multi-mode PFC converter, enabling a system to meet a variety of regulatory standards. It also features a minimum load-dependent start up function, as well as step start-up current control to reduce system inrush current. The CUS200M24 has a minimum start up voltage of 180VAC, and its built-in active power-factor correction (PFC) circuit works to reduce THD, as well as improve system efficiency. The PFC circuit helps to reduce power waste and improve overall system power efficiency.

The CUS200M24’s working principle is based on the use of a bridge rectifier and a voltage regulating circuit. When an AC voltage is applied to the CUS200M24 input, it will be converted to a rectified DC voltage by the bridge rectifier. This DC voltage is then converted to a regulated DC voltage by the voltage regulating circuit. This voltage regulating circuit consists of two main components: the voltage regulator and the DC-DC converter. The voltage regulator works to maintain a constant voltage at the output, while the DC-DC converter works as an amplifier to increase the output current. The output voltage can be adjusted by either the voltage regulator or the DC-DC converter.

The CUS200M24 also features a built-in EMI filter, which helps to reduce conducted and radiated emissions. The EMI filter consists of multiple stages, and its components are designed to handle a wide range of input and output frequencies. The CUS200M24 also features an internal thermal protection, which will automatically shut down the unit when it reaches a certain temperature. This ensures that the CUS200M24 is safe and efficient, and its components will not be damaged by an abnormal operating temperature.

In conclusion, the CUS200M24 is a high efficiency, multi-mode AC-DC converter that is commonly used in various application fields and industries. It is designed with built-in safety features that will help to ensure reliable operation. The working principle of the CUS200M24 is based on a voltage regulating circuit, which consists of a bridge rectifier and a voltage regulator and DC-DC converter. It also features a built-in EMI filter and a thermal protection, for improved performance and safety.
