The frequency converter for all applications where water or air needs to be moved
SINAMICS G120X: Master the elements
SINAMICS G120X is the new frequency converter from the proven SINAMICS family of drives – optimized for infrastructure and industrial water/wastewater applications as well as pumps and fans in building automation. This makes SINAMICS G120X the first choice for users who want to tap on the power of the elements to improve the quality of people’s lives. Part of a complete and seamless family of products, the frequency converter meets practically every requirement.
With SINAMICS G120X, users tap on the power of the elements for everyone's benefit.
The new 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.
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 with SINAMICS CONNECT 300, SINAMICS G120X also readies your drive application for digitalization.
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.
Specific functions for water / wastewater applications
SINAMICS G120X provides a deragging function to sustainably remove deposits and dirt from pump impellers. The pipe filling mode allows pipes to be gently filled at the beginning of the control process before going into closed-loop controlled operation. The innovative cavitation detection function protects pumps and reduces maintenance costs. The keep running mode reduces the speed before a possible shutdown. Multipump operation (staging) allows several pumps to be controlled from just one frequency converter. Many additional functions, directly supported by the converter, makes SINAMICS G120X universally applicable in infrastructure projects.
Delivered installed and ready-to-run with all essential features
When developing this new series of frequency converters , we placed the emphasis on simplicity – in every respect. So that you can quickly integrate SINAMICS G120X into your drive 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 SINAMICS CONNECT 300
- Simple maintenance: SINAMICS G120X indicates when service is required (using the Analyze MyDrives MindSphere application)
- Simply flexible: SINAMICS G120X can be operated with any motor – but most effectively with Siemens synchronous-reluctance motors
So that your drive application is always available
We have done a lot to adapt the reliability and the ruggedness of the SINAMICS G120X to address globally increasing customer requirements. This means that the frequency converter always 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.
SINAMICS G120X is rugged and can operate in almost any environment: 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. Coated modules are standard, 3C3 pollutant resistance is optionally available.
In addition, a comprehensive service portfolio is available to increase the availability and operation of the system. For the SINAMICS G120X, there is the option of an extended warranty up to 7 ½ years, various migration services and digitalization services.
So that your drive application is cost effective
To be both effective and cost efficient – these are key criteria for ideal converter operation. Both aspects have huge significance when it comes to state-of-the-art drive applications. The features with which we have maximized the efficiency of SINAMICS G120X have been appropriately optimized.
The frequency converters have an efficiency exceeding 98%. The flexibility of the converters when selecting an appropriate motor is also a big plus: The converter allows high-efficiency motors to be used for maximum energy-saving operation. 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.
The bypass function* allows the motor to be switched between converter and line operation to reduce energy consumption. The energy/flow calculator calculates energy saving and the flow value without requiring the installation of an external meter.
* Bypass function is only supported on induction motors
The digital transformation is in full swing. It offers a wealth of previously unimaginable possibilities when it comes to process optimization. With SINAMICS G120X, you can leverage all of these opportunities.
SINAMICS G120X can be easily connected to the Cloud via SINAMICS CONNECT 300. Your benefits: increased machine performance, increased availability, a higher degree of cost effectiveness and profitability, higher competitiveness. You not only secure the future of your company but also the quality of human lives that rely on your competence and vision.
