What advantages does DC current (continuous) have in powering the titanium anodes over AC (alternating current)?
ANSWER 10: Because the system uses DC current, the batteries can be used as a power source. The system uses sophisticated power regulators to control the battery usage and reduce the consumption necessary to protect the boat. The regulators send under 3 volts of current to the titanium anodes ensuring a minimal drain on the batteries. The system also makes it impossible to overprotect the boat. Even if someone were to turn the regulators to full power, it would never reach a reading of -1200mV: a reading still well below the point where paint begins to fall off.
