The Cathodic Protection Controller is designed for trouble free service in all environments and includes many special features which make it easy to operate and maintain in the field. Power consumption and heat generation are minimised in the CP since efficient solid state circuitry is used instead of ballast resistors typical of earlier cathodic protection units. The power circuit contains no moving parts to wear out or break down. Quality digital voltage and current meters provide output monitoring which facilitates field adjustment. This is easily performed by inserting a small screwdriver through the faceplate. Recalibration can be performed in minutes without special tools or meter equipment. Since corrosion protection systems normally operate in remote, unattended sites, they should be protected from the common effects that make them fail such as: lightning exposure, battery damage, and short – circuits. That’s why every Sollatek CP Unit includes lightning transient suppression, a low battery shutdown circuit and output overload protection. Our dual transient protection network will suppress electrical spikes and surges that normally damage field equipment. If the storage batteries become discharged due to cloudy days or photovoltaic system failure, the CP Unit will automatically shut down, preventing excessive discharge and protecting the battery from permanent damage and costly replacement. Our built-in circuit breaker prevents damage to the CP and other components, should the output leads become shorted to one another. To help reduce overall system cost, the CP includes adjustable current and voltage outputs. Standard photovoltaic modules can be used and the CP output adjusted to the desired level.
