Siemens Sinamics G120C AC Drives

Compact converters with rich functionality of the series SINAMICS G120C they show high power density indicators in operation, they are suitable for controlling electric motors up to 132 kW. The scope of application of this line of drives covers the following areas: various types of conveyor equipment, agitators, crushers, compressors, extruders, centrifugal pumps, fans (axial and radial) and other production plants. Easy commissioning and intuitive interface for configuration, long service life and reliable operation.

The series is available in seven body sizes, all of which provide significant workspace savings with equivalent performance. The three largest dimensions have a built-in DC reactor. Scalar (volt-frequency dependence) or sensorless vector control, support for popular industrial network standards, is used as a method of monitoring and evaluating operating parameters. The most modern software tools are already built in and allow you to quickly and visually interact with the electric drive system.
