Power and current ratings
The input current is affected by the supply voltage
and impedance. Therefore, to aid the selection of
cables and fuses, the values of Maximum
continuous input current stated are for the
worst-case condition.
The values of maximum current for models 1201 to
1205 are stated for a 200V
AC supply rated at ten
times the kVA of the Drive, with 2% negative
phase-sequence imbalance and a typical motor load.
The values of maximum current for models 2201 to
2203 and 3301 to 3304 are stated for a 200V
AC supply having a 5kA short-circuit capability and a
2% negative phase-sequence imbalance.
The values of Typical input current are stated
for a balanced 200V
AC supply having a 5kA
short-circuit capability; these values are given to aid
calculations for power flow and power loss.
