What Is an Electroplating Rectifier? - QEEHUAAn electroplating rectifier is a specialized power supply that converts standard alternating current (AC) from the grid into the precise, stable direct current (DC) needed for electroplating, allowing for uniform metal deposition onto a surface for decorative or protective purposes. It's a crucial device that controls the voltage and current, ensuring a consistent flow of electricity to move metal ions from a solution onto the workpiece, forming a smooth, even coating.
