Electroplating Rectifiers With Current Rating From 50 To 5000 Amps

Rectifier is an economical and the most efficient method of obtaining D.C. from A.C. supply for electroplating, anodizing and many other electro-chemical processes. The widest applications in the field of electro-plating normally require maximum voltage of 8V, 12V, 16V and 20V D.C. at various current capacities as per requirement. A range of current rating from 50 to 5000 Amps is covered in our regular range. * A.C. Input: VIRDI's electroplating rectifiers are designed for three phase 50 Hz A.C. input supply is suitable for operation at any voltage between 380/440 volts. Thus, it covers a wide range to cater for mains voltage fluctuations. The input to the rectifier unit is to be connected through a switch fuse unit of proper rating which is never included in the scope of supply and has to be procured separately. * Circuit: The circuit employed in Virdi's rectifiers is simple and universal. A.C. supply is given to an autotransformer which in turn supplies a variable voltage to the primary of a three phase double wound delta/doublestar connected transformer. The secondary of the transformer is connected to hexa phase/ bridge connected rectified using silicon diodes. The output is obtained from the rectifier and the star points of the transformer through an inter phase transformer. Applications: * Electroplating * Anodizing * Cleaning & other electrochemical processes * Barreling * Etching
