The frequency converter SINAMICS G120X from Siemens Master the elements for the pump/fan applications, the water/wastewater (W/WW) and building technology/HVAC sectors. The SINAMICS G120X impresses due to the straightforward selection and ordering, easy handling "out of the box" and simple integration in the application. Simple setup with the SINAMICS G120 Smart Access Module or the IOP-2 operator panel.

The SINAMICS G120X operates stably under all line conditions, optionally complies with the EMC categories C2 and C1, and is particularly robust due to its operating temperature from -20 °C to +60 °C. Specific industry functions such as tube filling mode and bypass function make the converter especially efficient. All devices in the series are harmonized and integrated in terms of their voltages and networks, as well as consistently designed for cost-optimized and resource-saving operation. Their compact design saves space in the control cabinet.

The SINAMICS G120X series are available in nine different frame sizes and performance ratings ranging between 0.75 kW and 630 kW. The SINAMICS G120X frequency converter can be put into operation easily using various options such as the external Basic Operator Panel (BOP-2), the Smart Access Module (SAM) and the Intelligent Operator Panel (IOP-2). SINAMICS – simply my drive!

The Siemens SINAMIC G120x series of converters are used in a wide range of industrial applications. Some of the most common are

Power units with DC link reactor for extremely high active power component thanks to efficient converter topology - for the same drive power, the converter requires a lower line current than comparable converters
Flux reduction through automatic adaptation of the motor current to the prevailing load conditions with closed-loop control modes V/f (ECO) and vector without sensor (SLVC) and savings of up to 5 % under partial load conditions
Hibernation mode dependent on set points in the process
High efficiency η ≥ 98 %
Local commissioning without specialized knowledge of converters thanks to default settings and graphical user interface
Unique: SINAMICS SD memory card for pre-parameterization and cloning of converter data sets
Data backup for easy replacement
Commissioning/diagnostics and controlling of converters
Four integrated PID controllers Distributed closed-loop control for motor-independent process control without higher-level controller (PLC)
Three freely programmable digital timer switches Control for freely selectable daily and weekly programs
