SINAMICS G120X

SINAMICS G120X, the low cost frequency converter - standardized and seamless when it comes to all supply voltages and supply types and is available in a power range extending from 0.75 kW to 630 kW.

Specific functions for water / wastewater applications

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 allows several pumps to be controlled from just one frequency converter.

Specific functions for HVAC applications

G120X 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. Multi-pump operation allows control of several pumps with just one frequency converter. Skipping critical motor speeds reduces vibration and, in turn, premature wear. Real-time clock for autonomous, time-controlled operation as well as a timestamp for fault and alarm reports.
