RD52.1-8N-132-R-V1-FW/S121

The Bosch Rexroth Indramat RD52.1-8N-132-R-V1-FW/S121 belongs to the RD 500 Drive Controllers series and serves as a high-performance DC supply inverter for industrial motion control. It operates at a nominal connecting voltage of DC 700 V with a tolerance of ±10% and delivers a rated power of 132 kW. The inverter features liquid cooling with internal pump technology to maintain optimal temperature during continuous operation. Designed without an integrated brake chopper, this unit type provides efficient energy conversion for demanding drive applications.

In detailed specification, the RD52.1-8N-132-R-V1-FW/S121 inverter dissipates 5.2 kW of heat during operation, necessitating adequate clearance from heat-generating equipment and ensuring reliable performance within an ambient temperature range of 0 to 40 °C. Above 40 °C, output derates until 50 °C, beyond which operation is not permitted. The controller supports selectable pulse frequencies of 4 kHz—yielding the full 132 kW motor output—and 8 kHz, where rated output reduces to 110 kW. The device is classified in size class G and weighs approximately 105 kg, offering a robust construction suited for heavy-duty industrial environments.

Additional features include a degree of protection rated IP20 per EN 60529, indicating resistance to solid objects ≥12 mm but requiring indoor cabinet mounting for enhanced environmental protection. A standby power function with an external 24 V DC supply preserves control electronics during main power loss. Installation and commissioning must be performed by qualified personnel to ensure safety and compliance. With global shipping availability and a one-year warranty, the RD52.1-8N-132-R-V1-FW/S121 delivers reliable, efficient, and durable drive control solutions that enhance productivity and process stability in industrial automation applications.
