The Siemens SINAMICS G120X is a modular frequency converter optimized for pump and fan applications in infrastructure projects. It offers high levels of integrated safety, energy savings, and network connectivity. Available power range from 0.75 to 630 kW. This series of converters is available in three voltage variants: 200-240 V, 380-480 V and 500-690 V. In addition, the SINAMICS G120X features a comprehensive safety package with an integrated Safe Torque Off (STO) safety function with SIL3 certification. Constructed with a rugged design and in accordance with 3C3 standards allows for operation under harsh environmental conditions. Thanks to its connection to the Cloud with SINAMICS CONNECT 300, SINAMICS G120X also prepares your drive application for digitalization.
Water / Wastewater Apllications
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.
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.
