Note 1.
The power supply capacity is the capacity for the Inverter’s rated output. It will vary depending on the impedance at the input power supply. (This is due to fluctuations in the power factor. The power factor can be improved by inserting an AC reactor.) There will also be variations in the ratio between the rated current of the motor that is used and the rated output current of the Inverter.
2.
The heat radiation is the electric power consumed in the Inverter at the
Inverter’s rated output.
