The specialized power units are engineered to effectively accommodate diverse electrical demand requirements.
Solar Array: Sized to provide enough wattage to maintain the protection current even during the "worst-case" winter months. A microprocessor-based power supply that regulates the output voltage and current to match the specific soil resistivity and pipe coating conditions. Battery reserve, typically engineered for 3 to 5 days of autonomy to ensure protection never dips during extended storm events. Reference copper electrodes provide a feedback loop to the controller to ensure the pipe-to-soil potential stays within the "protected" range.
