In some embodiments, an ICCP system includes an AC-DC rectifier receiving AC power from an AC power source and providing a DC output having a constant voltage or a constant current, a cathode connection electrically coupling the AC-DC rectifier to a structure to be protected by the ICCP system, current-emitting anodes arranged in parallel and receiving the DC output from the AC-DC rectifier, and a controller communicating with the AC-DC rectifier to set a maximum value for the constant voltage or constant current of the DC output. In other embodiments, an ICCP system includes a converter assembly including an AC-DC rectifier and a rectifier chassis enclosing and environmentally sealing the AC-DC rectifier. The ICCP system also includes an environmentally-sealed controller communicating with the AC-DC rectifier and an environmentally-protected Input-Output connection assembly. Junctions electrically connect the converter assembly, the environmentally-sealed controller, and the environmentally-protected connection assembly.
