Automatic cathodic protection rectifiers designed to provide precise, stable control of potential, current or voltage across a range of industrial and water and wastewater applications.
The IRT C.P. Sentinel Series offers automatic cathodic protection control to meet a broad range of application requirements. Available in air-cooled and oil-cooled configurations, these rectifiers use specialized controllers to maintain operator-selected output levels, with options for potential, current and voltage control. Features such as loss-of-reference shutdown on potential-control models, anti-spiking circuitry and high-energy AC and DC surge protection support reliable operation and accurate cathodic protection monitoring.
The series includes the Aqua-Line Air Series, developed for water and wastewater applications requiring IR-drop-free potential control; the Potential Control Series, designed for applications requiring stable “ON” or IR-drop-free structure-to-reference electrode potential; and the Current/Voltage Control Series, designed to maintain a selected DC output current or voltage.
