Tips: 2000A plating rectifier advantages

2000A plating rectifier uses IGBT switch rectification, PWM chopping technology + DSP microcomputer digital control technology and touch screen operating system. It has automatic constant current and automatic constant voltage control functions for unidirectional DC pulse and bidirectional DC pulse. The pulse amplitude is continuously adjustable, the pulse duty cycle is adjustable, and the frequency is adjustable as well. With good man-machine interfaceand the strong visibility, can automatically store and record electroplating current, voltage, bath temperature and other real-time process curves. Multiple sets of process parameters can be stored or recalled, and the degree of automation is high. It can greatly improve the finish, compactness, corrosion resistance, reduce porosity, eliminate hydrogen embrittlement, improve product coating quality, and save a lot of precious metals. It can be widely used as a rectifying power supply for pulse plating of precious metals such as gold, silver, palladium and titanium in aviation, aerospace, weapons, ships and other enterprises and scientific research institutes.
