Siemens Answers with the SINAMICS S150 Enclosed High Performance Regenerative Drive

SINAMICS S150 Enclosed Drive

SINAMICS S150 is an enclosed air-cooled AC/AC variable speed drive ideal for high performance applications that require power regeneration back into the power supply system.

As standard, the unit also contains a controller (CU320) with PROFIBUS port, an advanced operator panel (AOP30) and a terminal module (TM31) for digital and analog inputs and outputs. Standard interfaces guarantee quick integration into the plant and process control scheme, and easy start-up and operation.

SINAMICS S150 regenerative drives are available in several configurations covering a broad range of voltages and power ratings, with a wide variety of standard options to adapt to industry and site specific needs. It is ideal for applications with high requirements regarding dynamic response and speed accuracy, frequent braking cycles with high braking energies, and four-quadrant operation. SINAMICS S150 offers high-performance speed control with high accuracy and dynamic response. The user-friendly AOP30 operator panel with graphical LCD and plain-text display provides easy commissioning and parameterization using interactive menus, and alarm and fault logs.


  • Integral clean power filter technology
    with a THID of typically 3% or better, which meets the requirements of IEEE519-1992 under all operating conditions

  • Adjustable input power factor
    at unity or controlled in the range 0.8 leading to 0.8 lagging

  • Controlled DC link voltage
    allows stable motor operation also on weak or fluctuating power supply systems, able to compensate for even severe voltage dips and sags

  • Energy Regeneration with Smart Infeed or Active Infeed

SINAMICS S150 is offered in accordance with IEC or North American/NEMA standards. All versions/designs of SINAMICS S150 of a particular rating (IEC or NEMA) use identical drive electronics components – power module, CU320 controller and CompactFlash card, door mounted AOP30 operator panel and TM31 I/O module. Differences between the versions are found in the enclosure type and the power distribution/circuit components, as well as in the scope of auxiliary equipment included and excluded, and the range of available standard and custom options.

SINAMICS S150 to North American NEMA standards

The NEMA version was designed to meet the standards and codes applicable in North America.

  • Basic NEMA 1 enclosure, optional NEMA 1 filtered or NEMA 12 ventilated

  • Optional UL listing

SINAMICS S150 to IEC standards

The IEC version is offered in North America for customers that intend to export to other parts of the world. The IEC version is not suitable for installation in North America as it does not comply with NEC/CEC requirements.

  • IP20 enclosure, optional IP21, IP23, IP46, IP54
