6SL3202-0AE31-8SA0 SIEMENS Exclusive Sinus Filter Original Brand New

The 6SL3202-0AE31-8SA0 SIEMENS sinus filter is engineered to enhance the performance and lifespan of motors operated through SINAMICS drive systems. Designed for applications requiring stable voltage conditions, this filter minimizes electrical stress on motor windings and ensures smoother operation across a wide range of industrial environments. Its ability to reduce peak voltages and limit voltage rise (dv/dt) makes it a highly effective component for protecting equipment and extending service life. By creating a nearly sinusoidal output waveform, the filter contributes to reduced heating and a quieter overall operating profile.

This model supports 380–480 V 3AC systems with a current rating of 182.0 A, making it suitable for medium to large-scale installations where reliability and efficiency are essential. The filter allows the use of longer motor cables, offering flexibility in system layout and installation. By lowering bearing currents, it becomes possible to operate standard motors without requiring specialized insulation or insulated bearings, which contributes to simplified maintenance and reduced overall system cost.

In environments where electromagnetic compatibility is a crucial factor, the sinus filter delivers advantages by significantly lowering the rate of voltage rise on motor cables. This characteristic helps minimize electrical noise, and in many cases, short motor cable configurations may not require shielding to meet EMC standards. Furthermore, the suppression of converter-induced stray losses results in smoother motor behavior with noise levels comparable to direct mains-fed systems.

Overview

Sine-wave filters limit voltage peaks, reduce dv/dt stress, and support longer cable lengths. They improve EMC characteristics, minimize converter-related stray losses, and reduce motor noise. These filters also support standard motors without the need for specialized insulation or insulated bearings.

Important operational notes include permissible pulse frequencies between 4 kHz and 8 kHz for outputs up to 90 kW, an output frequency limit of 150 Hz, and the necessity of operating with a connected motor. Automatic pulse frequency reduction functions must also be disabled during operation.
