Description
Siemens frequency converters from the SINAMICS range are designed for reliable control of electric motors in industrial and infrastructure applications. They are used to regulate motor speed, torque and operating behavior in pumps, fans, conveyors, compressors, production machines and other motor-driven systems.
Depending on the application, Siemens offers different SINAMICS converter families. SINAMICS V20 is a compact and cost-effective basic converter for simple motion sequences, with a power range from 0.12 to 30 kW. SINAMICS G120C is a compact converter with integrated safety functions and a power range from 0.55 to 132 kW. SINAMICS G120 is a modular multifunctional converter for more flexible and demanding applications, with a power range from 0.55 to 250 kW. Siemens also offers specialized versions such as G120X for pumps and fans, as well as higher-power converter solutions for complex industrial systems.
These converters are suitable for machine building, water and wastewater systems, HVAC, production lines, conveyor systems, industrial utilities and automation projects where efficient motor control is required. The correct model is selected according to motor power, supply voltage, control method, overload requirements, communication interface, safety functions, application type and installation conditions.
