12 / 24 V @ 30 Amp Cathodic Protection Controller

Application

Used to control the current injected into the ground bed to prevent the rusting of iron and/or steel objects inbedded in the ground. This highly efficient highly and stable multiple control mode unit switches automatically between the various control modes to maintain the proper structure potential as the ground bed resistance changes with operating conditions.
