This advantage is proved by several tests and can also theoretically be explained.   Time saving: Experience shows that by using a pulsating waveform it is possible to carry out anodizing (and also other electrodeposition treatments) at a higher average current in comparison with conventional direct current.
This may well be due to the cooling of the oxide layer in the interval between two consecutive pulses, following the known “recovery” theory. Therefore by using pulse rectifiers it is possible to get the same thickness in shorter time, with the benefits of 20-25% approx. time saving.  BETTER QUALITY (by using the same average current)   Standard size: Output ampere: 600-30000A, output voltage:0-50V Other specification can custom according to customer requirement.   Pulse output waveform:   Imported Key component or self-exploited patent key components:                         Technical Datas:
