SINAMICS G120C parks a lot in a compact space

SINAMICS G120C Compact Vector Drive

SINAMICS G120C has been specially designed for machine manufacturers  looking for an economic, space-saving and easy-to-operate standard AC drive providing a surprisingly wide range of functions. This device combines compactness with superior power density and is characterized by fast installation and commissioning, user-friendly connections, and easy-to-use operating tools.

With its four frame sizes, the SINAMICS G120C covers a performance range of 0.75 to 25 HP (0.55 to 18.5 kW). The energy-efficient device serves the most common communication interfaces and is an integral part of Totally Integrated Automation.
