RD52.1-4N-045-L-NN-FW

The RD52.1-4N-045-L-NN-FW, Bosch Rexroth Indramat, RD 500 Drive Controllers section presents a robust industrial converter engineered for continuous operation under demanding conditions. This AC drive converter supports a nominal connecting voltage of 3 x AC 380-480 V and delivers a rated power of 45 kW. It features a converter format without a built-in brake chopper, optimizing installation flexibility for tailored regenerative solutions. The modular package includes a forced air cooling design that maintains optimal thermal performance across extended duty cycles.

Detailed specifications underscore the unit’s high-performance capabilities. The drive achieves a pulse frequency of 12 kHz to ensure precise motor control and low acoustic noise. Its output frequency spans from 0 Hz to 1400 Hz, accommodating both low-speed torque requirements and high-speed fan applications. An integrated chopper presents a minimum resistance of 5.8 Ω, while a field-oriented regulation line code of 02 provides smooth dynamic response. The IP20-rated enclosure complies with EN 60529, protecting internal electronics from foreign objects. The control unit is commissioned via an operator panel with a graphical display, offering guided parameterization and real-time diagnostics.

Engineers benefit from seamless integration into industrial automation networks, with protective-conductor grounding enforced before commissioning. The converter’s high overload margin and stable forced air cooling ensure reliable performance in continuous-duty applications. Together with Bosch Rexroth Indramat’s service network, the RD52.1-4N-045-L-NN-FW drive delivers the uptime and precision required for pump, fan, and material-handling installations.
