EH Air-Cooled Rectifier

C$ C$

The Corrpro® EH 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 and short circuit protection is provided by magnetic-trip circuit breakers, and output protection by means of semiconductor fuses. Primary AC/DC lightning protection is provided by metal oxide varistor (MOV) arresters. Output control using 25-steps of tap adjustment gives ample control of output settings. Conservatively rated full-wave diode bridge assemblies coupled with a high-performance transformer combine to yield an efficient and reliable rectifier for all cathodic protection installations.
