Transformer rectifiers are AC (alternating current)-powered electrical equipment that provide DC (direct current) for impressed current cathodic protection systems. Transformer rectifier units are often custom manufactured and equipped with a variety of features, automatic output adjustment, various type of electrical enclosures, for operation in single or three phase AC input.
Our air cooled cathodic protection rectifiers are industry leading in quality, workmanship and service life offering many years of trouble-free operation. Typically, air cooled rectifiers find wide application in pipelines, storage tanks, and many locations where continuous duty, DC cathodic protection power is required.
