Consult Amtech for the details on models AMT-011-X to AMT-030-X
The input power factor is 0.9 with 3% ACL
The inverter efficiency will be >98%
Note1: Indicates the total effective value including the higher harmonics
Note2: The maximum applicable motor output is given for a standard induction motor.
Note3: If the default carrier frequency is exceeded, derate the output current by 5% per 1 kHz as the reduced rating.
