SINAMICS G120

The modular multifunctional frequency converter

The SINAMICS G120 is a modular frequency converter for the most diverse requirements. The modular structure of the components and the wide power range from 0.55 to 250 kW ensure that you are always able to assemble the ideal converter for your requirements.

This series of converters is available in three voltage variants for connection to 200 V, 400 V and 690 V networks. In addition, the SINAMICS G120 features a comprehensive safety package. STARTER or SINAMICS Startdrive is used for commissioning the safety functions.

Host of combination options

The modular SINAMICS G120 converter system comprises the Power Module, the Control Unit, and an optional operator panel

The Control Unit controls and monitors the Power Module and the connected motor using multiple selectable closed-loop control types. It supports communication with a local or central controller and monitoring devices.

The Power Module supplies the motor in a power range from 0.37 kW to 250 kW. It features state-of-the-art IGBT technology with pulse width modulation for extremely reliable and flexible motor operation.

Comprehensive protection functions provide a high level of protection for the Power Module and the motor.
