The converter for every application involving water and air

SINAMICS G120X – Master the Elements: This converter is designed for HVAC applications in building automation as well as pump and fan applications in the water and wastewater industries. Because of this, SINAMICS G120X is the best option for harnessing the power of the elements to raise standard of living. The frequency converter is a seamless and comprehensive family of products that satisfies almost all needs.

Utilise the elements’ power

Applications involving pumps and fans in infrastructure projects are best suited for SINAMICS G120X.

Users can harness the power of the elements for the good of all with SINAMICS G120X.

With a power range spanning from 0.75 kW to 630 kW, the new frequency converter is offered as a comprehensive product line. It is standardised and seamless across all supply voltages and supply types. EMC limit values are maintained even at motor wire lengths of up to 150 m, and the devices are compliant with international EMC regulations. SIL3 certification is held by the integrated Safe Torque Off (STO) safety function.

Thanks to its rugged design with optional protection against dripping water, SINAMICS G120X can be used in harsh conditions. The frequency converter can also be operated under environmental conditions according to the 3C3 standard.

Thanks to its connection to the Cloud, SINAMICS G120X also prepares your drive application for digitalization.

Specific functions for water / wastewater applications

The deragging feature of SINAMICS G120X helps to clean pump impellers of deposits and grime in an environmentally friendly manner. Before switching to closed-loop controlled operation, the pipe filling mode enables pipes to be gradually filled at the start of the control process. The unique cavitation detecting feature lowers maintenance costs while safeguarding pumps. Before a potential shutdown, the speed is lowered in the remain operating mode. Multiple pumps can be managed with a single frequency converter thanks to multipump operation, also known as staging. The converter directly supports numerous new functions, which broadens the application of SINAMICS G120X in infrastructure projects.

Specific functions for HVAC applications

The flying restart function reduces starting times after brief power failures. SINAMICS G120X also provides an automatic restart function after power failures. The essential service mode maintains fan operation for smoke extraction systems or emergency ventilation systems for as long as required in extreme situations. Multipump operation (staging) allows for the control of several pumps with just one frequency converter.

Skipping critical motor speeds is another HVAC-specific feature. This reduces vibration and, in turn, premature wear.

SINAMICS G120X also provides a real-time clock for autonomous, time-controlled operation as well as a timestamp for fault and alarm reports.

System overview

appealing from all angles and appropriate for the future

The capabilities that are needed for infrastructure applications are perfectly provided by the SINAMICS G120X series. Everything you require to harness the power of nature is provided for the good of all.

Convincingly simple

Delivered fully functional, installed, and equipped with all necessary features

We prioritised simplicity above all else while creating this new line of frequency converters. in order for SINAMICS G120X to be swiftly integrated into your driving application.

  • Simple ordering (see the ordering systematics at the bottom)
  • Simple integration into existing applications
  • Simple commissioning (using the multi-color IOP-2 operator panel or Smart Access Module)
  • Simple operation, setup and settings
  • Simple connection to the Cloud using SIMATIC FDE Gateway, SIMATIC S7-1200/1500 SPS or SIMATIC IOT2040
  • Simple maintenance: SINAMICS G120X indicates when service is required
  • Simply flexible: SINAMICS G120X can be operated with any motor – but most effectively with Siemens synchronous-reluctance motors

Reliable & rugged

In order for your Drive application to always be accessible

We have made significant efforts to modify the SINAMICS G120X’s robustness and dependability in order to meet the ever-growing demands of our customers worldwide. This indicates that even in the face of variations in the line supply, the frequency converter always performs with a high level of stability. Devices with an integrated DC link reactor minimise harmonics up to 250 kW of power.

The SINAMICS G120X is a tough device that can function in nearly any setting. Depending on the model, its operating temperature range is -20°C to 60°C. The converter is IP20 compliant, with an IP21 alternative available in UL open type. Modules with coatings come standard, while 3C3 pollutant resistance is an optional feature.

To improve the system’s operation and availability, a full service portfolio is also offered. An extended warranty of up to 7.5 years, a variety of migration services, and digitization services are available for the SINAMICS G120X.

Efficient

In order for your drive application to be economical

The best converter operation must meet these two important requirements: it must be economical and efficient. In the context of cutting-edge driving applications, these factors are extremely important. The features that allow us to optimise the SINAMICS G120X’s efficiency have been suitably tuned.
The frequency converters are more than 98% efficient. Another significant benefit is the converters’ versatility in terms of choosing the right motor: High-efficiency motors can be utilised with the converter to maximise energy savings. The ECO mode makes sure that there are the least amount of losses and optimal performance for low dynamic loads. Additionally, it optimises the output power to lower the driving load’s energy consumption.

To save energy, the motor can be switched between converter and line operation using the bypass function*. Energy savings and flow values can be computed using the energy/flow calculator without the need to install an external metre.

SINAMICS G120X: Capable of handling any task

Make greater use of the data from your SINAMICS G120X to boost efficiency and transparency.

The shift to digital is well underway. It provides an abundance of hitherto unthinkable opportunities for process optimisation. You may take advantage of all of these chances with SINAMICS G120X.

There are multiple ways to link SINAMICS G120X to the cloud: using SIMATIC FDE Gateway as a serial interface solution, using SIMATIC S7-1200/1500 PLC, or using SIMATIC IOT2040 for direct PROFINET connections to Insights Hub.

Benefits for you include improved machine performance, greater availability, improved profitability and cost effectiveness, and enhanced competitiveness. You safeguard not just the company’s future but also the well-being of people whose lives depend on your skill and foresight.
