RD52.1-4B-045-L-V1-FW

The Bosch Rexroth Indramat RD52.1-4B-045-L-V1-FW from the RD 500 Drive Controllers series delivers a robust unit type Converter with a built-in brake chopper engineered for universal three-phase operation. It accepts a nominal connecting voltage of 3 x AC 380-480 V and provides a rated power of 45 kW for demanding applications. This Design 1 type module employs field-oriented regulation for high-precision motor control. Heat dissipation is managed by a forced air cooling mechanism optimized for continuous duty.

Featuring an integrated brake chopper, the RD52.1-4B-045-L-V1-FW supports a continuous brake power of 27 kW and a peak brake power of 111 kW (1 s) with a minimum chopper resistance of 5.8 Ohm. The converter draws a cooling air requirement of 0.2 m³/s to maintain stable temperatures. Enclosure protection meets IP20 standards (excluding connection terminals), guarding against ingress of objects ≥20 mm. Users can access the drive via a removable operator panel or through the intuitive RDwin PC software for rapid parameterization.

Built for industrial environments, this converter is rated to Size Class C and Environmental Class 3K3 per DIN IEC 721-3-3, with an operating ambient temperature range of 0 °C to 40 °C. Its modular hardware and software design ensures seamless integration into chemical plants, food packaging lines, and machine tools. The RD52.1-4B-045-L-V1-FW combines high performance, compact dimensions, and flexible commissioning options to streamline installation and maximize uptime.
