The QS10.481 AC/DC converters are a perfect example of the efficient and reliable power supply applications that can be achieved with modern high-efficiency technology. These converters are based on a full-bridge rectifier topology. A full-bridge rectifier is a type of AC to DC converter that converts alternating current (AC) to direct current (DC). It is typically used when relatively high currents are involved and the output voltage needs to be adjusted.

The QS10.481 includes an input stage rectifier, a voltage controller, a primary controller, an output stage rectifier, and an output voltage regulator. Input stage rectifiers convert AC voltage into DC voltage and are connected to the primary controller. Primary controllers are used to control the output voltage and current level of the device. Output stage rectifiers are used to convert the output power from the primary controller into a regulated DC output voltage. The output voltage regulator monitors and adjusts the output voltage accordingly based on the input from the primary controller and the output stage rectifier.

The main working principle of the QS10.481 converter is that AC voltage is supplied to the input stage rectifier and is converted into DC voltage, which is then supplied to the primary controller. The primary controller then limits the amount of power that can be drawn and adjusts the output voltage according to the required value. The output stage rectifier then changes the DC output voltage back to AC voltage and the output voltage regulator ensures that the output voltage is maintained within a specified range. This ensures that the device provides a consistent output voltage, even under varying load.

The QS10.481 AC/DC converters are primarily used in a wide variety of industrial and commercial applications. These applications include industrial power control systems, domestic appliances, office equipment, medical equipment, telecommunications systems, and test and measurement systems. Moreover, they are also used to provide power to telecommunications and IT equipment operating outdoors, such as base station antennas, routers, switches, and signal boosters. By using a full-bridge rectifier topology, the QS10.481 provide a reliable, efficient, and cost-effective solution for providing continuous power supply.
