AC DC Converters

The VOF-20B-S9 is an AC/DC Converter designed to safely and efficiently convert low power AC energy into DC energy. The device is suitable for use in various AC/DC converters, car chargers, and other low power devices, and is highly efficient up to 90%.The VOF-20B-S9 is designed to reduce the energy losses of an AC to DC conversion process. The device features a synchronous rectification controller and a high frequency transformer, both of which are necessary to create a high efficiency AC/DC conversion. The device also features protection against overload, overcurrent, and overvoltage, as well as a voltage controlled output protection.The device is designed to work in a range of input voltages from 90 VAC to 264 VAC, meaning it can be used in both domestic and international applications. The device is capable of converting these input voltages into DC outputs up to 20 V and 1.2 A, making it suitable for a wide range of low power applications.The device works by first using the synchronous rectifier controller to convert the incoming AC power into a DC voltage, which is then rectified to the desired voltage and current. This voltage is then passed through a series of components, such as resistors, capacitors, and inductors, to step down the voltage and current, while regulating the overall output. The components used in the circuit are carefully chosen to provide the most efficient conversion process possible, while still reducing energy losses.The device also features a voltage controlled output protection, which ensures that the output voltage does not exceed the set points, even if the output current is changed or disturbed. This is essential to protect the device from overvoltage and overcurrent, and helps extend the life of the device.The device is designed to work in both domestic and international applications, and is tested and approved to meet necessary global safety standards. In summary, the VOF-20B-S9 AC/DC converter is a highly efficient and reliable device, suitable for use in a wide range of low power applications.
