SINAMICS G120P Cabinet drive inverter cabinet units, versions A and C

With its SINAMICS G120P Cabinet drive inverter 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 into a specially designed cabinet enclosure. This design minimizes configuring and installation expenditure.

SINAMICS G120P Cabinet has been specially tailored to meet the requirements of drives for pumps, fans and compressors with quadratic load characteristic that have medium performance requirements with no regenerative feedback capability.

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

SINAMICS G120P Cabinet offers an economic drive solution that can be matched to customer-specific requirements using a range of available components and options.

There are two versions of the drive inverter cabinet units:

• Version A
  enables all optionally available line connection components, such as the main switch, main contactor, line fuses, line filter, motor-side components and additional monitoring devices to be installed
• Version C
  space-saving design with line reactor and optional main switch. This particularly slimline design can be used, for example, when line connection components are accommodated in a central low-voltage distribution panel (MCC) in the customer's plant or system.

SINAMICS G120P Cabinet drive inverter cabinet units are available for the following voltages and outputs:

The units have degree of protection IP20 as standard. They are optionally available with degrees of protection IP21, IP23, IP43 and IP54.
