Surface treatment rectifiers are DC power supply devices specifically designed for processes such as electroplating, electrolysis, and anodizing. Their performance directly determines the coating quality, energy consumption level, and production efficiency. With the advancement of intelligent manufacturing, these devices are evolving from simple power converters into key nodes for process intelligence.

Surface treatment rectifiers convert industrial frequency AC power into smooth DC power through a three-phase bridge rectifier circuit. The core technology lies in precisely controlling the ripple coefficient of the output voltage and current. High-quality rectifiers can control ripple to within 5%, ensuring uniform deposition of metal ions on the workpiece surface. Compared to ordinary industrial power supplies, their unique features include:

• Low ripple output: preventing defects such as pitting and blistering in the plating layer
• High-precision current/voltage regulation: current accuracy must reach ±1% to meet high-end process requirements
• Corrosion-resistant design: able to withstand the strong acid, alkali, and high humidity environments of electroplating workshops.
