AC/DC converters are devices that convert alternating current to direct current. They are often used for powering electrical equipment from mains sockets. The QS20.481 is a type of AC/DC converter specifically designed for medical applications. This article will discuss the application field and working principle of the QS20.481.

The QS20.481 is compliant with medical device safety regulations, and is approved to UL/EN/IEC60601-1 standards. It is intended for use in IT and laboratory equipment, medical diagnostic and treatment equipment, and class I and II surgical and non-surgical medical devices. It includes a wide range of features, such as recognition of standby and load conditions, an auto-ranging input voltage range, a high efficiency and low power consumption, and reliable overvoltage protection.

The QS20.481 uses a voltage regulator to convert AC input voltage into a regulated DC output voltage. The AC input voltage is rectified through a full-bridge rectifier made up of two diodes to the opposite direction. The input is filtered by a capacitor and then sent to the regulator. The regulator controls the amount of output voltage to the device it is powering, by measuring the difference between the output voltage and the reference voltage. The higher the input voltage, the more current sent to the device, and vice versa.

The QS20.481 is designed to be highly efficient. When the output load is in a lower range, the device is able to switch to an idle mode; this reduces the amount of power consumed by the device. When the output load is higher than 50%, the device is able to switch to a step-down DC/DC converter mode for improved efficiency. The combination of power saving features and efficient operation results in minimal power consumption and maximised efficiency.

The QS20.481 is designed for use in medical applications. It is able to meet the stringent safety and performance requirements of medical power supplies. It is also highly efficient and reliable, offering excellent power savings and a low power consumption. With its wide range of features and safety certifications, the QS20.481 is an excellent choice for powering medical devices.
