The Beginning
​
20 years ago in Durban, South Africa, 3 electronic engineers with previous experience in cathodic protection on ships and pipelines got together to try and overcome the many pitfalls of electronic rust protection for open air structures. They identified that if there was a way to combine the two proven technologies; impressed current and sacrificial anode; they could get the best of both and find an effective way to protect an open air structure using electronic rust protection. Combining these two technologies was a complex procedure as it is not a case of having them run in tandem, they need to be fully integrated. In 1988, after months of testing and adjusting, there was a breakthrough and the first RustStop® was made.


UPGRADED COMPONENTS
The key components on the RS-5 have been upgraded from commercial grade components to industrial standard components. This offers greater reliability and efficiency to ensure that the system operates effectively under all conditions. The use of over-spec components from world leading manufacturers like ON semiconductors, HP and Fairchild means that our system can handle any situation that can occur in a vehicle, and more
• NEW COMPONENTS
A few new components have been introduced, including the following:
​The UF4004 polarity protection diode which improves on reverse polarity protection,
The CMOS IC’s upgrade, has increased the voltage range, thus offering better over voltage protection to prevent damage from a faulty vehicle regulator or when the system is connected to the incorrect voltage supply,
New MOSFET technology, to reduce current draw (less than 0.009A under normal conditions) while maintaining
the systems effectiveness.
An on-board Pico-Fuse has been introduced which will pop if the system experiences a major fault to ensure
that it cannot draw any excess current (popped fuse still covered by warranty).
• NEW ENCLOSURE MATERIAL
The new RS-5 enclosure has been upgraded to the latest flame retardant plastic polymer material ensuring the
highest safety. The RS-5 itself could never cause a fire, but in the event of there being a fire in the engine
compartment, this new material ensures that the RS-5 will not ignite and will in fact self-extinguish any flame
contact.
• C-TICK APPROVAL
The new RustStop® RS-5 now complies to international EMC and RFI standards and has acquired
C-Tick approval. Overall RFI (interference) has been reduced by improving on the PC board ground
plane, PC board tracks and upgraded SABS approved wires.
• WATERPROOFING
New potting material and methods as well as modified internal enclosure design have increased the systems
overall waterproofing and reliability.
