  • Page 471: Using A Single Phase Power Source

    16 Using a Single Phase Power Source 16.1 Single Phase Rating The SV-iS7 series inverter is a three-phase variable frequency drive (VFD). When applying single- phase power to a three-phase VFD, there are several limitations that need to be considered.

    Using a Single Phase Power Source <Figure-2 Typical Single-Phase Configuration> 16.2 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 16.4 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.
