In the “worlds” of electroplating and industrial washing, the current rectifiers and pulsed current generators of the PE series are indispensable components for the electrochemical treatments envisaged in surface finishing systems. These current rectifiers and pulsed current generators have excellent regulation, programming and electrical efficiency qualities and are suitable for all types of electrochemical treatment, even when the applications are “demanding”. The PE series current rectifiers and pulsed current generators consist of the current rectifier and pulsed current generator elements, the elements for programming and control (control panel, or connector for Profibus interface systems, etc.) and the connecting elements. The current rectifier and pulsed current generator elements connected to the anodes and cathodes of the treatment tanks are electrically “connected” to the elements for programming and control through the connection elements. All types of current rectifiers and pulsed current generators are components made according to the technical specifications required by the customer.
