SMDF(S)-I(II)-WDY-PLC Series Micro Arc Anodizing Power Supply

SMDF(S)-I(II)-WDY-PLC Series Micro Arc Anodizing Power Supply

Introduction:
The micro arc anodizing power supply adopts IGBT switch rectifier, chopper technology, PLC, DSP microcomputer digital control technology and touch screen operation system. This oxidation power supply realizes single direction DC, single DC pulse and positive and reversing DC pulse multi-step automatic control of constant current. Pulse amplitude is continuous and adjustable, and pulse duty ratio and frequency can also be adjustable. With good human-computer interface and nice visibility, the micro arc anodizing power supply can automatically store and record micro arc anodizing current, voltage, bath temperature and other process curves in time. This oxidation power supply can store or invoke multiple sets of process parameters with high automation. It can greatly improve the hardness, anti corrosion and compactness of parts' anodizing film layer. It is extensively used in military services like aviation, aerospace, weapon and ship, etc. The micro arc anodizing power supply (micro arc oxidation power supply ) is also used in civilian industrial enterprises, scientific research institutes and national key material labs and material school of university that carry out micro arc anodizing on parts like aluminum, aluminum alloy, magnesium alloy, titanium alloy.
