Designed to drive up to eight low-impedance CDI coils, the CDI-8 effectively combines an 8 channel ignition expander with an 8 channel CDI module in one compact unit. The circuitry can reliably deliver 450 volt primary voltage at 15,000 RPM (or at 30,000 RPM for 4 cylinders). The output stages deliver up to 200 A into the CDI coil primary.
