Each element is controlled by it's own phase-angle fired SCR Power Controller.
Manual controls allow each element to be tuned for maximum life.
Voltage and current are automatically varied to provide the most economical, minimum power usage for optimum efficiency. Compensation in voltage for the change in resistance with age of the heating elements is automatic.
