Converter Cabinet Units SINAMICS G150

█

General information

SINAMICS G150 cabinets are ready-to-connect, high-output AC/AC converters in a standard cabinet. An extensive
range of electrical and mechanical options means that they can be configured easily to meet individual requirements.
They are designed for applications with less stringent requirements in terms of control quality and feature a simple,
6 - pulse rectifier, i.e. they are not capable of regenerative operation.
SINAMICS G150 cabinets are available for the line supply voltages and outputs listed in the table below:
Line supply voltage
380 V – 480 V 3AC
500 V – 600 V 3AC
660 V – 690 V 3AC
Line supply voltages and output power ranges of SINAMICS G150 cabinets
There are two versions of the SINAMICS G150 cabinets:
•
Version A
is designed to allow installation of all the available line connection components, such as line fuses,
main circuit breaker, main contactor, circuit breakers, line filter or motor-side components and
additional monitoring equipment. This version is also available in the higher power range with two
Power Units connected in parallel.
•
Version C
with specially space-optimized design without line-side components. This version can be used, for
example, when line connection components are accommodated in a central low-voltage distribution
panel (MCC) in the plant.
SINAMICS G150 cabinets are available in a range of cabinet widths, starting at 400 mm and increasing in increments
of 200 mm.
The standard model has a degree of protection IP20, but further models with degrees of protection IP21, IP23, IP43
and IP54 are available as options.
SINAMICS G150 cabinets feature as standard the AOP30 Advanced Operator Panel for control, monitoring and
commissioning tasks. It is mounted in the cabinet door.
The customer interface on the G150 is provided in the form of a PROFIBUS interface on the CU320 Control Unit and
the TM31 Terminal Module which adds a large number of analog and digital inputs/outputs.
The digital inputs and outputs on the CU320 Control Unit are used for internal purposes on G150 cabinets and are
not therefore available for use as a customer interface. The TM31 Terminal Module must always be used for this
purpose.

Rated data of converters for drives with low demands on control performance

Main applications
SINAMICS G150 cabinets are primarily intended for applications which require a lower standard of dynamic response
and control accuracy and are usually operated in sensorless vector control mode.
They are basically not capable of regenerative operation. For applications where the drive operates in regenerative
mode for brief periods, it is possible either to activate the V
L62).
Where the application requires a higher standard of control, i.e. where the control accuracy is more important than
the dynamic response, SINAMICS G150 cabinets can be equipped with an SMC30 speed encoder interface which
enables them to operate with TTL/HTL incremental encoders (option K50).
