Siemens releases Sinamics G120X drive series for pumps, fans and compressors

March 22, 2019 – Siemens has introduced the new Sinamics G120X drive, designed for use in pump, fan and compressor applications in industries such as pulp and paper, water/wastewater and other industrial environments.

Sinamics G120X has a power range of 1–700 hp (0.75–630 kW) and can operate in a temperature range from -4 to +140° F (-20 to +60° C) with any standard motor, including synchronous reluctance motors (SRM).

It has an integral DC choke, which the company says improves harmonics and EMC performance. Sinamics G120X meets all the latest and upcoming UL, NEMA and EN/IEC standards for 2019 and beyond and offers up to 100 kA short-circuit current rating (SCCR) for product safety and energy efficiency.

The compact design of the G120X saves space in the control cabinet and can also be integrated in to MCC solutions (including plug-in buckets). Even without an additional output reactor, Sinamics G120X drives enable motor cable lengths of up to 492 ft. (150 m) with category C2 or C3 filter and up to 1476 ft. (450 m) without filter and have hardware-based SIL3-certified safety functions built-in.  

The G120X has Class 3C3 coating which is suitable for harsh environments where the presence of corrosive gases such as hydrogen sulphide (H2S) is present. A high C2 or C1 EMC category ensures the drive can be reliably used in any kind of industrial and public networks.

Sinamics G120X can be linked to the cloud-based Siemens Mindsphere IoT operating system by using Sinamics Connect 300 and the Mindsphere app Analyze MyDrives. This offers users the opportunity to analyze valuable operating data gathered from the drive, and enables the visualization and analysis of status information, providing users with data that can be used as the basis for process optimization and maintenance strategies.
