An impulse power source is actually an on-off direct-circuit power supply. During the impulse power electroplating, the strong instantaneous current produced when the circuit is electrified will drive metallic ions to deoxidize under the extremely high electric potential and generate fine granule at the depositing layer, while when the circuit is broken, the density at the cathode will recover, allowing the use of high impulse current density in the next impulse cycle. MC serial impulse power sources are capable of improving functionality of the plate when used to electroplate gold, silver, nickel, tin and alloys, make the plate have uniform color, excellent brightness and corrosion resistance when used for protective or decorative electroplating, and achieve higher purity when used to purify precious metals. Impulse power is superior to the traditional electroplating power, and represents the trend of the electroplating power supply. Compared to single impulse power, SMC serial double impulse power can achieve more delicate plate and better brightness. The anodized dissolution produced by the reverse impulse of the double impulse power causes the density of metallic ions to quickly recover, conducing to application of the high impulse current density by the next cathode cycle and making the plate compact, bright and have less holes. The anodized peeling by the reverse impulse of the double impulse power greatly reduces content of organic impurities (including brighteners), making the plate high in purity and strong in resistance to color change. SMC serial double impulse power is applicable to electroplating of gold, silver, rare metals, nickel, zinc, tin, chrome and alloys, electroform of copper and nickel, anode oxidization of aluminum and titanium products, electrolytic polishing of precise parts, recharge of storage batteries and so on. Features of MC & SMC Serial Impulse Power 1. Impulse power source consumes less electricity by 25-30% than traditional electroplating power supply, with the efficiency exceeding 95%; electroplating value for workpieces. The reversal time for the double impulses can be preset with the switch, allowing automatic timing and automatic change of current direction. During the operation, the reversal time and cy
