Kaihong is a professional leader China Pulsed DC regulated power supply manufacturers with high quality and reasonable price. Pulsed DC voltage regulated power supply. In the process of pulsed electroplating, when the current is switched on, the electrochemical polarization increases, metal ions near the cathode region are fully deposited, and the coating is fine and bright. When the current is turned off, the discharge ions near the cathode region return to the initial concentration, and the concentration polarization is eliminated.
