2000 unit is the ‘power’ behind the system. The unit operates continually from
the vehicle battery and draws only 20-30 milliamps. The twelve volt DC charge is
then stepped up to a high voltage and transferred to the Capacitive Couplers.
The Capacitive Coupler then becomes charged so as to be the positive plate of a
capacitor, whilst the structure or vehicle becomes the negative side. The high
concentrations of electrons cause the surface to become covered by a layer of
electrons. These electrons are held static by the dielectric (usually the paint
or ferric oxide). The layer of electrons prevents or slows corrosion by lowering
the metals voltage potential which means the metal becomes less reactive and
therefore less likely to corrode. Corrosion/rust is a natural reaction. Put
simply electrons escape from unprotected metal, combine with atmospheric
molecules and ‘rust’ begins. The ERPS unit constantly replaces these electrons.
