Switchmode Rectifiers

Switchmode Rectifiers have been used for many years and this demonstrates the sophistication & ease of use for the quality service they provide. They also offer many extra features that can be installed in order to fit the specific Cathodic Protection needs. The switchmode rectifier is a newer technology and is significantly more advanced than transformer rectifiers utilizing high frequency switching devices resulting in far greater feedback responsiveness, efficiency & service life.

Switchmode Cathodic Protection rectifiers can typically be used with corrosion protection systems on pipelines, tank farms and other vulnerable metals, that are at risk of corrosion, where impressed DC currents are required.
