SINAMICS G120X frequency converter

Why SINAMICS G120X?

Master the elements: the SINAMICS G120X converter is optimized for pumps and fans in water and wastewater systems as well as HVAC applications in building automation. Its specialized functions, like deragging and cavitation detection, help provide reliable operation and pump protection to reduce your overall maintenance costs. Choose SINAMICS G120X for reliability and efficiency as you execute your infrastructure projects.The frequency converter comes as a complete product series – standardized and seamless when it comes to all supply voltages and supply types, and available in a power range extending from 0.75 kW to 630 kW. The devices are in compliance with global EMC standards and motor cable lengths of up to 150 m are permissible while maintaining EMC limit values. The integrated Safe Torque Off (STO) safety function is certified according to SIL3.

Key benefits

Set up with ease

You can quickly integrate SINAMICS G120X into your drive application, as it’s delivered installed and ready-to-run with all essential features. Enjoy simple ordering, integration, commissioning, operation, setup and settings.

Operate in extreme environments

SINAMICS G120X is rugged and can operate in most environments: its operating temperature extends from -20°C up to 60°C (depending on the exact version). The converter complies with IP20 with an option for IP21 in UL open type.

Improve efficiency and reduce costs

The frequency converters have an efficiency exceeding 98%. The flexibility of the converters when selecting an appropriate motor allows high-efficiency motors to be used for maximum energy savings.

Featured capabilities

Integrated DC link reactor

The frequency convertor reliably operates with a high degree of stability – even during line supply fluctuations. To reduce harmonics, up to a power of 250 kW, devices have an integrated DC link reactor.

ECO Mode

For low dynamic loads, the ECO mode ensures the best possible performance and lowest losses for low dynamic loads. It also optimizes the output power to reduce the energy consumption of the driven load.

Bypass function

The bypass function allows the motor to be switched between converter and line operation to reduce energy use. The energy/flow calculator calculates energy saving and the flow value without the installation of an external meter.
