RD52.1-4B-090-D-F1-FW

RD52.1-4B-090-D-F1-FW, Bosch Rexroth Indramat, RD 500 Drive Controllers delivers a robust field-oriented vector control solution optimized for industrial converters. It operates on a nominal connecting voltage of 3 x AC 380-480 V with a tolerance of ±10%, supplying a continuous rated power of 90 kW. The drive integrates a built-in brake chopper within its Converter with a built-in brake chopper architecture to manage regenerative energy. Designed for safety and longevity, the unit meets stringent EMC compliance standards for both noise emission and immunity.

Incorporating a plug-through cooler mechanism, the RD52.1-4B-090-D-F1-FW maintains thermal stability under heavy load while its AL electrolytic capacitors serve as a fortified DC link capacitors bank. The control offers an output frequency range of 0–250 Hz and employs a precision 22.5 mm mechanical grid for rack or panel mounting inside any control cabinet mounting configuration. Service and installation lockouts utilize standard M6 screws, and the module is specified for operation only in a dust-free environment to preserve internal electronics. A clear type plate displays all ratings, and the device carries a one-year warranty.

Engineers will appreciate streamlined integration into existing automation architectures—no additional brake resistors or external cooling loops are required. Its compact footprint and standardized grid pattern reduce cabinet redesign, while Bosch Rexroth Indramat’s support and the drive’s protective design ensure high reliability in machine tool and process applications. The RD52.1-4B-090-D-F1-FW stands out for its longevity, easy serviceability, and consistent performance under demanding conditions.
