A Plating Rectifier is an electrical power supply unit used in electroplating processes to convert AC (Alternating Current) into controlled DC (Direct Current) required for metal deposition on workpieces. It supplies precise voltage and current to the plating bath, enabling metal ions from the electrolyte solution to deposit uniformly onto the surface of the component.

Plating rectifiers are designed to provide stable, adjustable, and ripple-free DC output, allowing accurate control of plating thickness, adhesion, and surface quality. They are widely used in electroplating, anodizing, electroforming, and metal finishing industries, and are available in manual, semi-automatic, and fully automatic configurations.
