Overview
SINAMICS G150 drive converter cabinet units, versions A and C
With its SINAMICS G150 drive converter cabinet units, Siemens
is offering a drive system on which all line-side and motor-side
components as well as the Power Module are integrated ex-
tremely compactly into a specially designed cabinet enclosure.
This approach minimizes the effort and expense required to con-
figure and install them.
SINAMICS G150 has 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 enco-
ders are therefore superfluous.
However, the SINAMICS G150 converters are optionally avail-
able with an encoder evaluator in order to handle applications
that require an encoder for plant-specific reasons.
SINAMICS G150 drive converter cabinet units offer an economic
drive solution that can be matched to customers’ specific re-
quirements by adding from the wide range of available compo-
nents and options.
There are two versions of the drive converter cabinet units:
7 Vers io n A
All available line connection components, such as the main
switch, circuit-breakers, line contactor, line fuses, line filter, mo-
tor-side components, and additional monitoring devices, can
be installed as required. This version is also available with
power units connected in parallel.
7 Vers io n C
This offers an extremely space-optimized structure without
line-side components. This particularly slimline version can be
used, for example, when line connection components are ac-
commodated in a central low-voltage distribution panel (MCC)
on the plantside.
The SINAMICS G150 drive converter cabinet units are available
for the following voltages and power ranges:
Degrees of protection are IP20 (standard), and, as an option,
IP21, IP23, IP43 and IP54.
Global use
SINAMICS G150 drive converter cabinet units are manufactured
in compliance with relevant international standards and regula-
tions, and are therefore suitable for global use (# Technical
specifications).
