Siemens Releases G120X Drive Series for Pumps & Fans

29 October 2019

Siemens has recently introduced the new Sinamics G120X drive, a seamless and easy-to-use drive, designed for use in pumps, fans and compressor applications. 

Sinamics G120X has a power range of 1–700 hp (0.75–630 kW) and can operate in temperature ranges from -4 to +140° F (-20 to +60° C) with standard motors, including synchronous reluctance motors (SRM). It has an integral DC choke which improves harmonics and EMC performance. The drive meets all the latest UL, NEMA and EN/IEC standards for 2019 and beyond and offers up to 100 kA short-circuit current rating (SCCR) ensuring enhanced product safety and energy efficiency.

Sinamics G120X is compliant with all relevant EU and upcoming NEMA energy-saving standards and offers an operating efficiency level of over 98% (efficiency class IE2). Its comprehensive range of integrated application-specific functions for pumps and fans ensures improved energy efficiency through the use of eco mode to automatically change the output voltage either up or down slightly to find a minimum input power or implementing efficiency optimization to change motor flux to optimize system performance and minimize energy losses.

The compact design of the G120X saves space in the control cabinet and can also be easily integrated in to MCC solutions. 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 drive has Class 3C3 coating, which is suitable for harsh environments where corrosive gases such as hydrogen sulfide (H2S), chlorine (Cl) or ammonia (NH3) are often present. A high C2 or C1 EMC category ensures the drive can be reliably used in any kind of industrial and public network.
