SMDF(S)-MDY-PLC DC Superimposed Pulse Anodizing Power Supply

WHFD-DY-PLC High Frequency Inverter Soft Switch Anodizing Power Supply

Description:
This DC power supply adopts thyristor and IGBT switch rectifier technology, PLC, DSP microcomputer digital control technology and touch screen operation system. DC superimposed pulse anodizing power supply owns anodizing current's automatic control and DC superimposed pulse output control. Pulse duty ratio and frequency can be adjustable. With good human-computer interface and nice visibility, this DC power supply can automatically store and record real-time process curves of anodizing current, voltage, bath temperature, etc. It can also store or invoke multiple sets of process parameters with high automation, which can greatly improve the hardness of anodizing film layer. DC superimposed pulse anodizing power supply can be widely used in military services like aviation, aerospace, weapon and ship, etc. This DC power supply  can also be used to carry out common anodizing and hard anodizing on parts like aluminum, cast aluminum, aluminum alloy, magnesium alloy, titanium alloy and composite materials, etc.
