Product description

The Siemens SINAMICS G120C is a compact variable frequency drive (VFD) designed for a wide range of industrial applications. It operates on a 3-phase 380-480V AC power supply. This model provides a rated power of 0.55kW for low overload conditions (150% for 3s) and 0.37kW for high overload conditions (200% for 3s). It includes an unfiltered external 24V supply, an I/O interface with 6DI, 2DO, 1AI, 1AO, and an integrated Safe Torque Off function. Fieldbus communication is supported via USS/MODBUS RTU. The drive has an IP20 protection rating and is UL Open Type certified.

This VFD is ideal for controlling the speed of AC motors in applications such as conveyor systems, pumps, fans, and general machinery where precise speed control and energy savings are required. Its compact size (FSAA, 173x73x155mm) allows for easy integration into control cabinets.
