SIEMENS 6SL3130-7TE28-0AA3 Product Description

The SIEMENS 6SL3130-7TE28-0AA3 is a SINAMICS S120 booksize active line module designed to supply stabilized DC bus power for multi-axis servo drive systems. This active line module accepts 3AC 380-480V input and delivers 600V DC, 133A rated output with 80kW power capacity, adopting internal air cooling for cabinet installation. This active line module supports power regeneration back to the grid, reducing energy consumption during motor deceleration and braking cycles. This active line module comes with DRIVE-CLiQ interface for high-speed digital communication with motor modules and control units in the S120 drive group.

This SIEMENS regulated power supply unit maintains constant DC link voltage regardless of grid fluctuation and dynamic load variation. Its high-performance power rectifier unit converts three-phase alternating current into stable direct current to feed the shared DC bus. The power rectifier unit uses advanced IGBT technology to achieve low harmonic distortion and improve power factor of the whole drive cabinet. The power rectifier unit integrates comprehensive protection functions including overvoltage, undervoltage, overcurrent and overtemperature protection to safeguard the entire drive system. The compact layout of the power rectifier unit helps reduce overall cabinet volume for multi-axis machine configurations.

The module works in tandem with S120 single motor modules to build a common DC bus drive architecture for synchronized motion equipment. Reliable dc bus power regulation stabilizes DC link voltage during rapid acceleration, deceleration and heavy load switching. Stable dc bus power regulation enables regenerative energy recycling, cutting operational power cost for high-cycle production machinery. Precise dc bus power regulation suppresses voltage spikes caused by motor braking and protects downstream servo power units. Robust dc bus power regulation ensures consistent power supply even when multiple axes run simultaneously under peak load conditions.

The SIEMENS 6SL3130-7TE28-0AA3 has IP20 protection grade and adopts modular booksize design for side-by-side cabinet assembly. It supports full diagnostic functions, recording fault alarms and operating status for maintenance troubleshooting via STARTER engineering software. The built-in DRIVE-CLiQ connection simplifies wiring and supports automatic module identification during commissioning. It complies with IEC and CE international standards, widely used in CNC machine tools, printing machines, textile equipment and metal forming production lines. As the core power supply component of SINAMICS S120 multi-axis drive system, this SIEMENS active line module provides high-efficiency and stable DC power support for demanding industrial motion control applications worldwide.
