Siemens SINAMICS G120
The SINAMICS G120 frequency converter is designed to provide precise and cost-effective speed/torque control of three-phase motors.
SINAMICS G120 is a modular converter system that essentially comprises two function units:
- Control Unit (CU)
- Power Module (PM)
The Control Unit controls and monitors the Power Module and the connected motor using several different closed-loop control types that can be selected. It supports communication with a local or central controller and monitoring devices.
The Power Module supplies the motor in the power range 0.37 kW to 250 kW. It features state-of-the-art IGBT technology with pulse-width-modulated motor voltage and selectable pulse frequency. Comprehensive protection functions provide a high degree of protection for the Power Module and the motor.
The Control Units can be combined with the following Power Modules, PM240-2 and PM250
