Electroplating rectifier is a kind of electronic device which changes high voltage alternate current (AC) into low voltage direct current (DC). Electroplating rectifier is a very crucial component for any industry. For different industrial applications the electroplating rectifiers are available in a range starting from 1 Volt to 1000 Volts, to suit varying industrial requirements. Today these rectifiers are being used for various electro- chemical processes like Anodizing, Hydrogenation and more. Electroplating is a technique accomplished through electro deposition process. The process involves producing a coating, mostly metallic, on a surface by the action of electric current. Electroplating rectifiers are single phase or three phase devices on the basis of their rating. Generally, 8V, 12V, 16V, 20V, 24V rectifiers are used in industries having current rating of 500Amp and above.
