Application
This is 8000A rectifier for hard chrome plating and electroplating water cooling or air cooling are available.
For hard chrome plating, normally the current value is higher, up to 10000A, 20000A, 25000A or more. We developed up to 30000A 12V IGBT based rectifier specially used for hard chrome plating.
Hard chrome plating is the plating on a variety of substrate surface with a thickness of chromium coating, its thickness is generally more than 20um, making use of chromium's characteristics to improve parts' hardness, wear resistance, temperature resistance and corrosion resistance and other properties.
Application Field
The IGBT rectifier is used for the fields wherever require DC output power. such as:
Electrochemistry: Plating, anodizing, electro polishing, electrolysis, electro winning, electro refining, electronic cleaning, tinning, pickling, surface coloring, cathode protection
Heating: Inductive heating, DC heating, single phase AC heating
Water treatment:Waste water treatment, seawater desalination
Others: other fields require DC power
Working principle
The circuit takes alternating current (AC) from the wall outlet and converts it into a positive direct current (DC) output.
