MagneStep is a voltage step controller designed to adjust the protection potentials in sacrificial anode cathodic protection systems. Using a MagneStep, it is possible to select one of four steps to keep the protection potential within the acceptable limits, thus avoiding over-protection voltages.

MagneStep is a voltage-based device which provides protection potentials to be almost independent of the protection current. The protection current can range from micro-amperes to amperes with little difference in the protection voltage.

MagneStep also provides a relatively high fault current path (>100A) which provides self-protection under fault conditions. The MagneStep is also fail safe, which means the anode will always be connected to the protected structure even if the fault current exceeds the MagneStep’s rating.
