RD52.1-4N-200-R-NN-FW

The Bosch Rexroth Indramat RD52.1-4N-200-R-NN-FW from the RD 500 Drive Controllers series by Bosch Rexroth Indramat delivers robust, high-power AC drive conversion in a single, compact unit. Designed for three-phase grids, it supports a nominal connecting voltage of 3 x AC 380-480 V with a tolerance of ±10%, ensuring stable operation under voltage fluctuations. With a rated power of 200 kW, the converter excels in demanding industrial applications such as machine tools, conveyor systems, and process technology. Its unit type: converter without a built-in brake chopper simplifies integration where external braking units are preferred.

Able to handle dynamic loads, the RD52.1-4N-200-R-NN-FW features an output frequency range of 0–150 Hz driven by advanced flux vector control for precise torque and speed regulation. The drive is equipped with a liquid cooling with internal pump mechanism that maintains optimal thermal performance even at full load. Classified per DIN IEC 721-3-3 as environmental class 3K3, it operates reliably up to 40 °C ambient temperature. Encoders—incremental, resolver, or sin-cos—link via fiber-optic peer-to-peer connections for high-speed feedback and minimal electromagnetic interference.

Built for industrial endurance, the controller meets IP20 protection degree per EN 60529, guarding against solids greater than 12 mm while permitting internal airflow. The removable operator panel with a four-line graphical display simplifies commissioning and on-site diagnostics, and firmware updates are offered as optional modules to tailor functionality. Backed by a one-year warranty through Wake Industrial, the RD52.1-4N-200-R-NN-FW combines power density, precision control, and modular flexibility for the toughest drive challenges.
