RZS02.1-6-135

The RZS02.1-6-135, Bosch Rexroth Indramat, RZS Sinusoidal Filters opens a new chapter in drive system protection with its robust sinusoidal filtering capabilities. This precision-engineered filter maintains a Connecting Voltage of 3x AC 380 – 400 V ±15% (0 – 200 Hz) and supports a Max. Rated Current of 135 A at nominal line conditions. The unit’s Line designation of 2 aligns it perfectly with dual-line applications requiring high electromagnetic compatibility. Its compact, modular housing ensures straightforward integration into existing control cabinets without sacrificing accessibility or serviceability.

In detailed performance terms, the RZS02.1-6-135 features a low-pass cutoff that smooths inverter output into an almost perfect sine wave, reducing motor bearing stress and shielding sensitive electronics from harmful reflections. Its nominal current rating of 135 A handles peak inverter currents while its power class of 090 accommodates short-duration overloads without saturation. The filter’s low DC resistance minimizes voltage drop across the device, preserving drive efficiency and thermal stability. A dedicated 2-line code structure ensures symmetrical attenuation across both phases, translating to reduced audible noise and lower radiated emissions.

Engineers will value the RZS02.1-6-135’s plug-and-play footprint: it installs directly ahead of the inverter, delivering immediate protection against intense voltage spikes and preserving motor insulation integrity. Proven reliability in harsh industrial settings makes it ideal for automated material handling, packaging lines, and precision machining centers. With Bosch Rexroth Indramat’s reputation for durability, this filter streamlines commissioning and extends system uptime under challenging operational demands.
