The power rating in kVAis determined by the following equation:
3. Input Voltage (V) x Current Rating (A)
The values shown on the tables 9.1.2 to 9.1.5 were calculated considering
the inverter rated current rating and an input voltage of 230 V for 220-230 V
models, 460 V for 380-480 V models, 575 V for 500-600 V models and 690 V
Rated Output Current is valid for the following conditions:
RelativeAir Humidity: 5 % to 90 %, non condensing.
(3.300 ft) – nominal conditions.
From 1000 m to 4000 m (3.300 ft to 13.200 ft) – with 1 % current reduction
for each 100 m (330 ft) above 1000 m (3.300 ft).
0 ºCto 40ºC (32ºF to 104 ºF) - nominal conditions.
From 0 ºC to 55 ºC (32 ºF to 131 ºF) - with 2 % current derating for each
1 ºC (1.8 ºF) degree above 40 ºC (104 ºF).
The rated current values are valid for the indicated switching frequencies.
The 10 kHz switching frequency is not possible for the 2.9Ato 79A/500-
600 V, 107A to 472 A/500-690 V and 100A to 428 A/660-690 V models.
The operation at 10 kHz is possible for V/F Control Mode and Vector
Control with Encoder Mode. In this case it's necessary to derate the
output current according to table 9.1.
