Features:

  • 16 kW rated infeed and regenerative power (35 kW max) with 30 A DC link current for multi-axis SINAMICS S120 drives.
  • Booksize format (100 mm width) with internal air cooling, saving cabinet space while providing 65 kA short-circuit strength.
  • Regenerative feedback capability returns braking energy to the line, reducing energy costs and eliminating the need for braking resistors.
The 6SL3130-6TE21-6AA4 is a Smart Line Module that serves as the front-end power supply for SINAMICS S120 multi-axis drive systems. It converts 3-phase AC line voltage (342-528 V) into a regulated DC link that powers multiple connected Motor Modules. Unlike standard diode bridges, this module is regenerative, meaning it feeds braking energy back into the line instead of dissipating it as heat in braking resistors. This reduces energy consumption and cabinet cooling requirements. The rated infeed and regenerative power is 16 kW (21 kW for S6 duty, 35 kW maximum), with a DC link current of 30 A at 540 V DC (27 A at 600 V DC). Maximum DC link current is 59 A.

This slim profile allows multiple modules to be mounted side by side in a shared cabinet, maximizing power density. The module weighs 7.0 kg and has IP20 protection. It uses internal air cooling with 0.016 m³/s airflow, suitable for ambient temperatures up to 40°C. Installation altitude is up to 1,000 m without derating. The module includes screw-type terminals for line connection (2.5-10 mm² / AWG 14-8) and an integrated shield connection plate for EMC compliance. The DC link busbars support up to 100 A.

The regenerative capability of the 6SL3130-6TE21-6AA4 is a key advantage for applications with frequent deceleration cycles, such as centrifuges, winders, and test stands. By returning energy to the line, the module reduces overall power consumption and eliminates the need for external braking resistors. The module has a short-circuit strength of 65 kA when used with recommended Class J fuses or UL489 circuit breakers. Power losses are 0.190 kW at rated power, with a sound pressure level of 60 dB. The electronics power supply requires 24 V DC (20 A busbar ampacity) and draws up to 0.95 A. The module meets CE and cULus standards and includes built-in radio interference suppression (category C2 with line filter).

The 6SL3130-6TE21-6AA4 Siemens Line Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
