SMDF(S)-JDY-PLC Asymmetric AC Pulse Anodizing Power Supply


Asymmetric AC pulse anodizing power supplies adopt high frequency inverter soft switch rectifier technology, PLC, DSP microcomputer digital control technology and touch screen operation system. This AC anodizing power supply is controlled automatically by multi steps with anodizing current. With good human-computer interface and nice visibility, asymmetric AC pulse anodizing power supplies can store or invoke multiple sets of process parameters with high automation. The AC anodizing power supply can be extensively applied to military services like aviation, aerospace, weapon, ship, and so on. The asymmetric AC pulse anodizing power supplies are also used in civilian industrial enterprises that carry out sulfuric acid anodizing, chromic acid anodizing, phosphoric acid anodizing, sulfur phosphoric acid anodizing, sulfur boric acid anodizing and oxalic acid anodizing rectifier power of aluminum, cast aluminum, aluminum alloy, magnesium alloy, titanium alloy, composite materials, etc.
