Note: 1. The power supply capacity, is the capacity when the Inverter is operating at its rated output. The value will vary with the
impedance at the input power supply side. (Because the power factor of the input power supply changes, the power factor
will improve if an AC reactor is inserted.) The ratio with the rated current of the motor used and the rated output current of
the Inverter will vary.
2. The “heat radiation” is the power consumed in the Inverter when it is operating at its rated output.
