RD52.1-4N-011-L-V1-FW

The Bosch Rexroth Indramat RD52.1-4N-011-L-V1-FW belongs to the RD 500 Drive Controllers series and delivers precise motor management with a nominal connecting voltage of 3 x AC 380-480 V and rated power of 11 kW. This converter without a built-in brake chopper efficiently converts a 530–670 V DC input voltage range with an input voltage tolerance of ±10%, ensuring stable performance. The drive’s forced air cooling mechanism supports sustained operation even at elevated load, while selectable pulse frequencies of 4 kHz and 8 kHz enable fine-tuning of switching dynamics. Housed in a robust IP20 protection category enclosure with size class B dimensions, this controller integrates seamlessly into compact control cabinets.

Designed as a fully modular unit, the RD52.1-4N-011-L-V1-FW offers flexibility through firmware and hardware options, including a 24 V standby power supply for parameterization and field-bus operation when the main DC link is offline. The absence of an integrated brake chopper allows users to install external choppers where regenerative braking is required, simplifying maintenance and reducing unit complexity. Its converter topology assures consistent current delivery across the motor’s operating spectrum and accommodates variations in mains voltage without derating. With a lightweight design and optimized heat sink architecture driven by forced air throughput, the drive sustains near-rated output in continuous duty cycles.

Engineered for demanding applications—ranging from packaging and conveyor systems to chemical process and food machinery—the RD52.1-4N-011-L-V1-FW demands only specified ambient conditions for reliable service. Storage in a clean, dry environment between –25 °C and 70 °C preserves component integrity, and prefiltered inlet air safeguards against dust-related faults. By adhering to recommended mounting and ventilation guidelines, operators ensure long-term performance and safeguard sensitive electronics against aggressive or conductive gases.
