    Using a Single Phase Power Source <Figure-2 Typical Single-Phase Configuration> 12.2 Power(HP), Input Current and Output Current When using a three-phase VFD with single-phase input, derating the drive’s output current and horsepower will be necessary due to the increase in DC bus ripple voltage and current. In addition, the input current through the remaining two phases on the diode bridge converter will approximately double, creating another derating consideration for the VFD.

    Using a Single Phase Power Source 12.4 Wiring and Peripheral Device It is important that input wiring and branch circuit protection be selected based on the drive’s single-phase input current rating indicated in Table 1–2. The single-phase input current after derating differs from the three-phase input indicated on the VFD nameplate.
