Product Description:

The RZS01.1-5-034 is a passive line filter manufactured by Bosch Rexroth Indramat and supplied within the RZS Sinusoidal Filters series. Designed for cabinet mounting downstream of an inverter output, the device shapes the converter’s switching waveform into a sinusoidal voltage so that standard motors can run cooler, quieter, and with reduced electromagnetic emission in automated production lines. As part of drive systems that employ AC output stages, the device prevents cable reflection issues over long motor leads. It is commonly applied where inverter-fed motors must operate with standard winding insulation and stable acoustic behavior. This filtering action also helps limit steep voltage transitions at the motor terminals during routine drive operation.

Electrically, the filter operates on a line-to-line input of 3 x AC 500 V, matching typical converter outputs used in factory automation. Its windings and core are sized for a continuous load of 34 A, allowing it to pair with drives that feed moderate-power induction or synchronous machines. During operation, the filter dissipates 180 W of heat, a figure that must be considered for panel ventilation. It supports a motor control span from 0 ... 100 Hz, enabling low-speed torque as well as nominal running speed without saturating the magnetic circuit. For converters that switch at carrier frequencies near 8 kHz, the filter presents the necessary inductance and capacitance to attenuate high-frequency voltage edges while keeping fundamental losses low. In use, the filter smooths the pulse-width-modulated waveform before it reaches the motor, which can reduce electrical stress on connected equipment during continuous duty.

The unit is matched to converter power classes of 022 / 030, ensuring impedance and thermal capacity are correct for those drive sizes. Input voltage may deviate within a window of ±10 % without compromising waveform quality, giving tolerance against normal grid variation. The product is part of Product Line 01 and uses Design Version 1, which distinguishes it within the series and supports consistent documentation. These identifiers help separate this filter from other members of the same product range without changing its intended electrical role.
