Feature Specification
Line operating voltage 3 AC 380 V … 480 V ± 10%
The permissible voltage depends on the operational altitude
Input frequency 47 Hz … 63 Hz
Modulation depth 87% (The maximal output voltage is 87% of the input voltage)
Power factor λ 0.9
1.5 x Nominal output current (150% overload) for 57 s every 300 s Overload capability (HO)
5.5 kW ... 75 kW
2 x Nominal output current (200% overload) for 3 s every 300 s
1.1 x Nominal output current (110% overload) for 57 s every 300 s Overload capability (LO)
7.5 kW ... 90 kW
1.5 x Nominal output current (150% overload) for 3 s every 300 s
Inrush current Less than rated input current
Pulse frequency
4 kHz standard
The pulse frequency can be changed manually in 2 kHz steps.
Increasing the pulse frequencies above standard leads to an output
current reduction.
Electromagnetic
compatibility
Power Modules with untegrated class A filters according to EN 55011
available.
Braking Dynamic braking with regeneration (up to 100% output rating)
Protection level IP20
Temperature range
without derating (HO)
5.5 kW ... 75 kW
0 °C … +50 °C (14 °F … 122 °F)
Temperature range
without derating (LO)
0 °C … +40 °C (14 °F … 104 °F)
Temperature range with
derating
Higher operational temperature is possible with power derating
Storage temperature -40 °C … +70 °C (-40 °F … 158 °F)
Humidity < 95% RH - non-condensing
In areas of high relative humidity, measures should be taken to ensure
that condensation does not form within or around the SINAMICS G120.
Anti-condensation heaters are commonly used to prevent the formation of
condensation.
Pollution According pollution degree level 2
Do not install the SINAMICS G120 in an environment which contains
atmospheric pollutants such as dust and/or corrosive gases.
