Siemens 6SN1145-1BA00-0BA0 Overview

Siemens 6SN1145-1BA00-0BA0

The Siemens 6SN1145-1BA00-0BA0 is a sophisticated and versatile 611-D Infeed/Regen Feedback Module designed to operate within the SIMODRIVE 611 system. This module serves a crucial role in industrial applications by connecting the drive group to the line supply and generating the necessary DC voltage for the DC link. With a power rating of 16/21 kW, it is equipped to handle demanding tasks and provides regulated power for various operational requirements.

Infeed Modules and Application: 

The primary purpose of the 6SN1145-1BA00-0BA0 infeed module is to establish a connection between the drive group and the line supply. It plays a pivotal role in generating the required DC voltage for the DC link, ensuring a stable and reliable power source for the connected components. The module is compatible with different line supply voltages, including 3-phase 400 V AC ±10% at 50 Hz/60 Hz, 3-phase 415 V AC ±10% at 50/60 Hz, and 3-phase 480 V AC with a range of +6% to -10% at 50 Hz/60 Hz.

Line Supply Compatibility: 

The module's compatibility extends to different line supply configurations. In cases where the infeed modules are connected to non-standard or unconventional line supplies, specific considerations are necessary. An additional transformer with separate windings in vector group yn is required, particularly when dealing with upstream transformers or alternative line supply voltages such as 3-phase 200 V/220 V/240 V/440 V/500 V/575 V AC ±10% at 50 Hz/60 Hz.

Cooling Solutions: 

The 6SN1145-1BA00-0BA0 module incorporates advanced cooling mechanisms to ensure optimal performance and prevent overheating. Two cooling options are available:

Internal Cooling: 

Infeed modules can be equipped with internal heatsinks that facilitate cooling within the control cabinet. For wider 300 mm modules, a pipe cooling option is also available, allowing direct air cooling through a connected pipe.

External Cooling: 

Alternatively, modules can feature external heatsinks for cooling. These heatsinks are inserted through openings at the rear of the cabinet and cooling is managed on the customer's side. This configuration may require a mounting frame for each module.

Module Arrangement and Installation: 

Proper module arrangement and installation are crucial for maintaining safe and efficient operation. Between module groups mounted at the same height, a minimum lateral clearance of 50 mm must be maintained. To guide air efficiently over the module heat sinks, externally mounted fans and air baffle plates can be added, especially for modules with a width of 100 mm. Other module widths may require custom baffle plates based on the provided dimensions.

The Siemens 6SN1145-1BA00-0BA0 infeed/regen feedback module stands as a reliable and robust component within the SIMODRIVE 611 system. With its capacity to generate regulated power from various line supply voltages and its advanced cooling options, the module ensures the stability and efficiency necessary for demanding industrial applications. Its integration capabilities and versatile cooling solutions make it valuable in optimizing processes and enhancing operational reliability across various industries.
