The VOF-300-48 are AC DC Converters which are specially designed with a wide input voltage range of 90-264VAC, and provide a highly efficient system with low output ripple. It is mainly used for industrial applications and can supply up to 300 watt, providing high reliability without compromising performance.The VOF-300-48 is built with an advanced soft-switching technique, which enables it to deliver a constant, smooth and highly efficient power. The device is also equipped with a SMD package with high reliability and a low-profile design for space-saving applications. Furthermore, the VOF-300-48 includes over current, over voltage and over temperature protection as a safety measure.When it comes to the working principle of the VOF-300-48, this unit uses a rectifier for the AC input voltage. It then goes through a low-frequency power factor correction phase, which allows the AC input current to closely follow the waveform of the voltage. This makes the device highly efficient and prevents electrical noise.The rectified output generated by the rectifier is then converted into DC by means of an advanced Soft-Switching technique. This technique employs the principles of constant frequency PWM topology, meaning that the switching frequency is kept constant throughout the operation for better power conversion. The Soft Switching technique enables the device to achieve higher efficiency ratings and ensures peak performance and a smooth output.The DC output of the device is then provided to the output via a buck converter. This converter has a wide output voltage range, which means that it can be adjusted accordingly depending on the requirements. The buck converter is also designed with an active PFC function for high efficiency.In addition to its efficiency, the VOF-300-48 also provides an impressive power density with a high power rating. Its ultra-thin design is often used in applications where there is limited space or weight restrictions. The whole device is enclosed in a rugged casing for better protection of the internal components.Overall, the VOF-300-48 is a great choice for power converters and provides high efficiency and performance in a small package. Its improved efficiency, low profile design and wide output voltage range make it an ideal choice for industrial applications.
