Siemens Sinamics G120 AC Drives

General industrial modular frequency converters of the series SINAMICS G120 They have a universal set of functions and capabilities for a wide range of uses, three voltage options for organizing the drive's power supply. Designed to control electric motors in the power range up to 250 kW, there are six body dimensions available, maximum compactness of the design and a high level of power density. It supports popular industrial network protocols, and innovative software is built in for easy adaptation, start-up and operation of the electric drive.

Thanks to the modular construction concept, you can always choose the most optimal option for the necessary requirements. It is possible to use a wide range of encoder interfaces, as well as positioning functions, an advanced security system (STO, SS1, SBC, SLS, SDI, SSM) and energy recovery without additional devices.

SINAMICS G120 applications include conveyor and lifting equipment of various types, radial and axial fans, compressors, agitators, crushers, mixers, extruders, hydraulic and dosing pumps, packaging plants and other production applications.
