Providing the necessary electrical power for painting metal surfaces, known as Electro-Deposition, is an organic coating process that uniformly applies thin primers and single-layer coatings on automotive and household appliance products. ED painting is widely used in the automotive industry. Applying high-quality DC voltage over the entire voltage range, for a precise time, with an adjustable slope along with real-time reporting of the performance of individual anodes and the amount of painting of each workpiece, requires the simultaneous use of advanced rectification technology, online control and industrial automation in the design and implementation of the ED rectifier system. By achieving this special technology, KhazarTransfo specialists have provided the most reliable solution for the automotive and household appliance industries.
