Rectifiers & D.C. Power Supply Systems

Low-voltage thyristor rectifiers for electroplating and electrolysis


Electroplating: galvanizing, tin – plating, chromium – plating, nickel – plating, blackening, silver – plating, etc. Plants for sewage water treatment, coagulation. Electrolysis of copper, gallium, magnesium dioxide, silver, etc. Regeneration of electrolyte – electrowinning.

Used in

– supplying customers with direct single– or different pole current;             
– forming the intricate current characteristics: pulse, reverse, etc.
