The Siemens SINAMICS G120C Series Inverter Drive is a compact and robust device designed to provide efficient speed and torque control of three-phase motors. With a power rating of 4 kW and an operational voltage range of 380 to 480 V ac, this inverter is well-suited for a variety of industrial applications. It offers a wide frequency output of 0 to 550 Hz when operating in V/F Control mode and 0 to 240 Hz in Vector Control mode, catering to diverse operational requirements.
The inverter's design is optimised for space-saving installation, with dimensions of 73 x 196 x 203 mm, making it an excellent choice for situations where space is at a premium. The SINAMICS G120C is engineered to handle both Low Overload (LO) and High Overload (HO) conditions, ensuring reliable performance and adaptability to fluctuating load demands.
This inverter drive is unfiltered and operates with a power factor of 0.70 to 0.85 and an impressive efficiency rating of 0.97, which contributes to energy savings and reduced operational costs. The sound pressure level is a quiet 52 dB, minimising noise in the working environment.
For integration into various control systems, the inverter includes a PROFIBUS DP communication interface, multiple digital and analog inputs/outputs, and a PTC/KTY interface for motor temperature monitoring. The device is also equipped with an integrated fan for air cooling, ensuring it operates effectively within an ambient temperature range of -10 to 40 °C.
The SINAMICS G120C Series Inverter Drive is compliant with international standards, including UL, cUL, CE, and C-Tick (RCM), ensuring it meets the rigorous safety and performance requirements for the UK and global markets. Its advanced features and reliable performance make it a valuable component for optimising industrial processes and machinery efficiency.
