Siemens 6SL3131-7TE28-0AA3 SINAMICS S120 Active Line Module
A booksize Active Line Module with 380–480 V three-phase input, 600 V DC output, 133 A rating and external air cooling.
Overview
6SL3131-7TE28-0AA3 is an 80 kW SINAMICS S120 Active Line Module in booksize format. It converts a three-phase line supply into the regulated DC-link power used by a compatible S120 drive line-up and supports regenerative energy feedback through the Active Line Module architecture.
The 6SL3131 prefix identifies external air cooling, separating the power-section heat path from the main cabinet space. The exact 0AA3 version includes the specified DRIVE-CLiQ cable and must not be confused with the internally cooled 6SL3130-7TE28-0AA3.

Features
- Active Mode regulates the DC-link voltage independently of line-voltage variation within the supported operating arrangement.
- Smart Mode maintains the DC-link voltage in proportion to the rectified line voltage when selected for the application.
- Regenerative operation returns suitable braking energy through the line-side system instead of relying only on resistive dissipation.
- External air cooling moves most power-section heat through the designated rear cooling path.
- The included DRIVE-CLiQ cable supports integration into the SINAMICS S120 control and diagnostics architecture.
Applications
- Multi-axis SINAMICS S120 drive line-ups requiring an 80 kW regenerative infeed.
- Machine tools, production machines and motion systems where controlled DC-link voltage supports dynamic drive operation.
- Cabinet designs that use external air cooling to reduce power-loss heat released into the electronics compartment.
- S120 installations engineered with a compatible Active Interface Module, line-side protection, DC-link components and Control Unit.
Lifecycle
- Use the complete 6SL3131-7TE28-0AA3 article number for service planning because cooling method, power level and version suffix are part of the identity.
- Do not substitute the internally cooled 6SL3130 form solely because it shares the 80 kW class; cabinet cutout and thermal routing differ.
- Before replacement, record the Control Unit project, DRIVE-CLiQ topology, Active Interface Module, line filter, DC-link arrangement and external-air path.
- Check line-side protection, fan airflow, DC-link polarity and commissioning data before enabling the replacement infeed.
FAQ
What rated power does this exact article provide?
It is the 80 kW Active Line Module with a 133 A, 600 V DC output rating.
What does the 6SL3131 cooling variant indicate?
It identifies the externally air-cooled booksize construction.
Can 6SL3130-7TE28-0AA3 be treated as a direct mechanical substitute?
No. The 6SL3130 product uses internal air cooling, so the cabinet and cooling arrangement must be reviewed.
What is the difference between Active Mode and Smart Mode?
Active Mode regulates the DC link independently, while Smart Mode keeps it proportional to the rectified line voltage.
Which line-side component requires verification?
The compatible Active Interface Module, filtering and protective devices must match the engineered S120 system.
What should be backed up before exchange?
Retain the Control Unit project, DRIVE-CLiQ topology, infeed parameters and complete line-side configuration.
