Sinamics G150 - Technical Support

SINAMICS G150 drive converter cabinet units, version A and C

SINAMICS G150 drive converter cabinet units are designed for variable-speed drives in machine building and plant construction.

They have been specially tuned to the requirements of drives with quadratic and constant load characteristics, with medium performance requirements and without regenerative feedback.

The control accuracy of the sensorless vector control is suitable for most applications, and additional actual speed value encoders are therefore superfluous.

However, the SINAMICS G150 converters are optionally available with an encoder evaluator 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 matched to customers' specific requirements by adding from the wide range of available components and options.

The SINAMICS G150 drive converter cabinet units are available for the following voltages and outputs:

 

Supply voltage	Output
380 V to 480 V	110 kW to 560 kW
660 V to 690 V	75 kW to 800 kW

Degrees of protection are IP20 (standard), and as an option IP21, IP23 and IP54.

 

There are two versions of the drive converter cabinet units:

• Version A
  All the required line connection components, such as the main control switch, circuit breakers, main contactor, line fuses, line filter, motor components, and additional monitoring devices, can be installed as required.

• Version C
  With its particularly space-optimized structure without the line-side components. This version can be used where the line connection components are accommodated in a central low-voltage distribution panel (MCC) on the plant side.
