Automatic Air-Cooled Rectifier

The Corrpro® Automatic Series of custom air-cooled rectifiers combines top quality components and manufacturing methods with a wide variety of features and available options, resulting in an industry-leading solution for cathodic protection.

Available modes of operation with this series are constant current or constant potential control with voltage limiting. The AC input supply is isolated by a step-down transformer before being applied to a fully controlled, SCR, full-wave bridge assembly. This controlled and rectified voltage is filtered by a choke and capacitor combination (optional) to yield a low ripple DC output. The low ripple has the advantages of increased efficiency, no communication interference and more precise control of the output.

Rectifiers are constructed in natural convection, air-cooled, rugged steel enclosures rated Type 3R or, optionally, Type 4 or 4X. Enclosures are typically finished with a white, fusion-bond, polyester powder paint.

The Corrpro® Automatic Series of rectifiers provides the best choice for automatic control of your cathodic protection current & potential requirements.
