60V 2000A High Frequency Switch Power Supply For Hard Chrome Plating

60V 2000A high frequency switch power supply for hard chrome plating

 
During the oxidation process, the workpiece continuously generates gas, hindering the continued oxidation, making the oxide film loose and porous, and the intermittent high and low current conversion rectifier of the pulse power rectifier works, which is conducive to the precipitation of gas, easy to form a film, the film thickness increases, the oxide film It is denser, and its hardness, thickness and color are greatly improved. At present, the commonly used oxidation power supply is a DC power supply, and its output has no pulse, so the output generated is relatively loose, and the thickness, hardness, and color of the oxide film cannot reach the effect of pulse oxidation rectifier;
Superior performance of hard oxide pulse rectifier:
 
1-32 minutes adjustable soft start time, and can be used as a pulse soft start, especially suitable for hard oxidation process;
1-256 minutes running time is adjustable (independent of soft start time), automatic shutdown;
Multiple working options: pure pulse, pulse superposition, DC, etc .;
During the operation, it can display all operating parameters at any pulse frequency, duty cycle, pulse-based high & peak value, so that you can fully control what workpiece is in the end;
Under operating conditions, the parameters can be freely modified, adjusted, and stored at any time. After the power is turned off, the time is saved for 35 years. The stored parameters will be automatically run at the next startup;
According to the anodizing characteristics of aluminum and titanium, the working method is current stabilization and voltage limiting work to ensure sustainable and efficient oxidation. With the extended power bath of electrical solutions, the thickness of the oxide film increases if the output voltage rises to safety In the set value tree, the voltage stops rising, and crent gradually decreases, which really protects the workpiece from melting;
Perfect safety guarantee measures, with a variety of intelligent fault protection, over current, fault phase, phase sequence error, short circuit;
The transformer coil winding and bus bar are made of high-quality copper (copper content 99.99%), with good conductivity and high current efficiency;
The transformer coil adopts double vacuum impregnation process, which has good insulation and corrosion resistance.
