Compliance
AC30 series Variable Speed Inverter
Supply Harmonic Analysis (Frame N - Normal Duty)
Drive Type = Three Phase, Fundamental Voltage = 400V
Assumptions: Rsce = 120 at 400V where Q
1n
is the rated rms value of the
fundamental voltage of the supply transformer. The results meet the limits
specified in IEC61000-3-12:2011 (Table 4).
