Minimum resistance which can be
External (According to EN12015, EN12016)
Average sound pressure level
*1) Rated capacity is calculated by regarding the output rated voltage as 440V .
*2) Output voltage cannot exceed the power supply voltage.
*3) These values correspond to the following conditions: carrier frequency is 8 kHz (2 phase modulation) and ambient
temperature is 45°C.
Select the inverter capacity such that the square average current during operation is not higher than the 80% of the
rated current of the inverter.
*4) Voltage unbalance [%] =
(Max.voltage [V] - Min.voltage [V])/ Three-phase average voltage [V] x 67 (IEC61800-3)
*5) The power supply capacity is 500kVA (ten times the inverter capacity when the inverter capacity exceeds 50kVA), and
the value of the power supply impedance is %X=5%.
*6) The admissible error of minimum resistance is ±5%.
