SINAMICS G150 converter cabinet units, versions A and C

With its SINAMICS G150 converter cabinet units, a drive system is available on which all line-side and motor-side components are integrated together with the Power Module extremely compact into a specially designed cabinet enclosure. This approach minimizes the effort and expense required to configure and install them.

SINAMICS G150 has been specially designed to meet the requirements of drives with square-wave and constant load characteristics, with medium performance requirements, and without regenerative feedback capability.

The control accuracy of the sensorless vector control is suitable for most applications, which means that an additional actual speed value encoder is not required.

SINAMICS G150 converter cabinet units are optionally available with an encoder evaluation function in order to handle applications that require an encoder for plant-specific reasons.

SINAMICS G150 converter cabinet units offer an economic drive solution that can be adapted to customer-specific requirements through a wide range of components and options.

SINAMICS G150 is available in two versions:

• Version A
  All optionally available line connection components, such as the main switch, circuit breakers, line contactor, line fuses, line filter or motor-side components and additional monitoring devices, can be installed as required. This version is also available with power units connected in parallel.
• Version C
  Offers an extremely space-optimized structure without line-side components. This particularly slimline version can be used, for example, when line connection components are accommodated in a central low-voltage distribution panel (MCC) in the plant.

The following voltages and power ratings are available:

Degrees of protection are IP20 (standard) and optionally IP21, IP23, IP43 and IP54.
