Switchmode rectifiers are known for their quality, efficiency, service life and workmanship. Switchmode rectifiers have been used for many years and this demonstrates the quality service they provide.Many extra features 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 and service life.

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