1. Inverter Input Current
■
This section describes selecting peripheral devices and cables.
Table 3.1 Various current value through inverter
NOTE: • The inverter efficiency is calculated using individual value by capacity. The input effective value current is obtained for following condi-
tions:
[30HP or smaller]
• Power source capacity : 500kVA
Power source impedance : 2.5%
[40HP or larger]
• Power source capacity and impedance are calculated using values corresponding to Fuji's recommended capacity.
• For different power voltages such as 230V or 380V, input current is in inverse proportion to the power voltage.
50Hz, 200V (400V, 100V)
60Hz, 220V (440V)
