TECHNICAL SPECIFICATIONS
NOTE!
(1) The power rating in VA is determined by the following equation:
The values shown in the table were calculated by considering the
rated inverter current, input voltage of 220V for the 220-240V models
and input voltage of 440Vfor the 380-480 models.
(2) Rated current is valid for the following conditions:
Relative air humidity: 5% to 90%, non condensing.
Altitude : 3300 ft (1000m), up to 13200 ft (4000m) with 10%
derating/3300 ft (1000m) of the rated current.
Ambient temperature: 32º to 104ºF (0...40º C) (up to 122ºF (50ºC)
with 2%/ºC derating of the rated current).
The rated current values are valid for the switching frequencies of
2.5kHz or 5kHz (factory setting). For higher switching frequencies,
10kHz and 15kHz, consider the values shown in the description of
the parameter P297(refer to chapter 6).
(3) Maximum Current:
Inverter supports an overload of 50% (maximum output current
= 1.5 x the rated output current) during 1 minute for each 10 minutes
of operation. For higher switching frequencies, 10kHz and
15kHz, consider the values shown at the description of the parameter
P297(refer to chapter 6).
(4) Rated input current for single-phase operation.
Note: The models CFW080016B2024..., CFW080026B2024...,
CFW080040B2024..., CFW080073B2024... and CFW080100B2024...
can be operated both with single-phase voltage and three-phase voltage
without output current derating.
(5) The indicated motor power ratings are only orientative values for IV-pole
motors and normal duty loads. The precise inverter sizing must
consider the actual motor nameplate and application data.
