RD52.1-8C-075-L-V1-FW

The Bosch Rexroth Indramat RD52.1-8C-075-L-V1-FW from the RD 500 Drive Controllers series is a high-performance DC supply inverter designed for precision control in demanding industrial environments. As an Inverter operating as RD52 SFT, it delivers a nominal connecting voltage of DC 700 V and a rated power output of 75 kW, making it ideal for applications in chemical and process technology, machine tools, conveyor systems, and foodstuff machinery. Its primary function is to convert DC link voltage into a controlled three-phase AC output, enabling smooth acceleration and deceleration profiles with field oriented vector control.

This drive controller is engineered with a robust forced air cooling mechanism, requiring a cooling air flow of 0.4 m³/s to manage thermal dissipation efficiently. With a rated power loss of 1.85 kW, the unit maintains optimal operating temperatures while minimizing energy waste. The RD52.1-8C-075-L-V1-FW features radio interference suppression conforming to level A2 per EN 55011 / EN 61800-3, ensuring electromagnetic compatibility in sensitive installations. Packaged in a size class D housing with IP20 protection and a weight of 32 kg, it is mountable within standard control cabinets and can be installed adjacent to other units using tapped-rail mounting.

Compatibility and ease of integration are enhanced by support for 24 V DC standby power, which sustains control electronics when the main line supply is removed. At an elevated DC link of 750 V, the drive achieves a rated apparent power of 92 kVA with a peak of 119 kVA (60 s), delivering rated currents of 104 A and peak currents of 135 A for short-term overloads. The drive’s modular design with mounting rails permits multiple units to be installed side by side without clearance gaps, simplifying system layouts. Globally shippable with a one-year warranty, this inverter controller combines reliability, efficiency, and compliance with industry standards to optimize productivity and reduce downtime in critical industrial operations.
