Siemens Sinamics S150 AC Drives

Frequency converters of the line SINAMICS S150 designed to work with uniaxial electric motors with a capacity of up to 1200 kW with variable speed. The ideal solution for production applications where high performance indicators, dynamics characterized by frequent high-energy braking stages and four-quadrant control (regeneration) are required. At the discretion of the customer, the standard equipment can be supplemented with optional modules and accessories from a wide list of available products.

This series is also equipped with a Clean Power filter, thanks to which the system is characterized by minimal indicators of nonlinear distortion. The modular design is very compact, installation, start-up and adjustment of the drive does not cause any inconvenience. Simplicity and ease of handling have been achieved through the use of pre-installed software algorithms and a user-friendly user interface.

The basic equipment includes the following units: chassis modules, control, sensor, and terminal blocks, an extended control panel for the operator. All sensitive elements are protected from the effects of aggressive media by a special coating. Popular applications of SINAMICS S150 include centrifuges, elevator and crane equipment, test benches, presses, cutters, energy-intensive conveyor belts, winches, etc.
