AC DC Converters and the TUNS500F28The use of electricity in industrial and residential applications is ever-increasing. This is, in part, due to the development of high-tech, efficient and robust AC (alternating current) to DC (direct current) converters. The TUNS500F28 is one such product, with reliable features and a wide range of applications.The TUNS500F28 is a high-efficiency AC/DC converter with wide input voltage range, high power density, and low temperature rise. It features active power factor correction (PFC) and isolation transformer. With its high power density and advanced protection features, the converter allows for robust operation in both harsh and benign environments. Its wide input voltage range gives it the flexibility to operate between 85V –265VAC, allowing it to be deployed in a variety of applications.The advanced PFC stage of the TUNS500F28 further increases the efficiency to more than 0.9, making this converter a prime choice for high-power applications. In addition, the TUNS500F28 also features isolation transformer for the input. This helps to reduce the amount of harmonic distortion reaching the power supply and limit the amount of power that the converter draws from the main power source.In terms of applications, the TUNS500F28 can be used for a wide range of applications, such as UPS, solar energy harvesting, digital signage, and lighting systems. The converter has also been designed with an edging current for more robust operation even in extreme environmental conditions.In terms of working principle, the TUNS500F28 is designed to convert AC power from the mains into DC power with a high efficiency rating. The converter features two stages of operation: the PFC stage, which reduces the AC voltage and increases the power factor to a value greater than 0.9; and the DC/DC stage, which further steps down and shapes the voltage waveform into one suitable for the application.In conclusion, the TUNS500F28 is a powerful and reliable AC/DC converter with robust features and a wide range of applications. With its wide input voltage range, high efficiency, and advanced protective features, it is a prime choice for applications ranging from industrial to residential.
