Custom Air-Cooled Rectifier

The Corrpro® Custom Air-Cooled Rectifier combines top quality components and manufacturing methods with the best features, resulting in industry-leading cathodic protection rectifiers. Incoming AC power is stepped down, isolated and rectified to a controlled DC output. Input overload & short circuit protection is provided by magnetic-trip circuit breakers. Output protection by means of semiconductor fuses in the transformer secondary.

Primary AC/DC lightning protection is provided by high energy metal oxide varistor (MOV) arrestors and secondary surge suppression by disk-style MOVs. Output control uses 25-steps of tap adjustment, giving ample control to output settings.

Conservatively rated full-wave diode bridge assemblies coupled to a high-performance transformer combine to yield an efficient and reliable rectifier for all cathodic protection installations.
