Ask for AvailabilityThe Bosch Rexroth Indramat RZS02.1-6-135 is a sinusoidal filter from the RZS Sinusoidal Filters series. It is designed for a connecting voltage of 3 x AC 380 to 400 V with a voltage tolerance of ±15 percent and a nominal current of 135 Amps. This filter handles a maximum output frequency of 200 Hz and features a pulse frequency of 8 kHz with a power loss rating of 400 Watts.
Internal Product Review
The RZS02.1-6-135 is a Bosch Rexroth Indramat sinusoidal filter well suited for improving output quality in drive systems. A 3 x AC 380 to 400 V connection and 135 A nominal current make the unit a strong match for substantial industrial loads. Operation across 0 to 200 Hz supports broad application flexibility, and the 8 kHz pulse frequency is a key performance advantage.

Product Description:
The RZS02.1-6-135 sinusoidal filter is produced by Bosch Rexroth Indramat and belongs to the RZS Sinusoidal Filters series. The unit sits between a PWM inverter and the motor, reshaping steep-edged drive pulses into a smoother sine wave so cable stress, motor insulation wear, and acoustic noise are reduced in industrial automation cells. By lowering dv/dt at the motor terminals, it supports long cable runs and helps meet electromagnetic compatibility targets in multi-axis machine tools and material-handling lines.
Electrically, the filter is rated for a line connection of 3 x AC 380 … 400 V, permitting installation on standard 400 V systems, and it remains functional within a tolerance band of ±15 %, giving headroom for supply fluctuations common to large plant grids. Its core network is tuned to cover 0 … 200 Hz, so the same assembly can accompany variable-frequency drives that control low-speed positioning or high-speed spindles without retuning. Internal inductors are sized for a carrier or pulse frequency of 8 kHz, which is a typical switching rate for modern IGBT converters. Thermal dissipation is limited to 400 W, so cabinet ventilation must remove that continuous loss during operation.
For load handling, the filter carries a nominal phase current of 135 A, matching converters in the 090 power class and allowing proportional motor current on the output side up to its specified upper frequency. The identifier 6 in the type code corresponds to wiring cross-sections, while the design index 1 indicates mechanical dimensions from the first manufacturing release. The product line code 02 places the module among second-generation low-dv/dt accessories used with compatible frequency inverters. This arrangement supports consistent electrical integration with matched drive and motor combinations.
