RD52.1-4N-200-F-V1-FW

The Bosch Rexroth Indramat RD52.1-4N-200-F-V1-FW from the RD 500 Drive Controllers series is a high-performance field-oriented vector control unit. This converter without a built-in brake chopper operates on a nominal connecting voltage of 3 x AC 380-480 V and delivers a rated power of 200 kW. It employs a forced air cooling with integrated liquid circulation mechanism to ensure thermal stability under continuous operation. The compact design combines rugged construction with advanced electronics for reliable integration into industrial automation systems.

Safety and reliability are central to the RD52.1-4N-200-F-V1-FW’s design. The device features a line code of 52 and mandates a copper conductor cross-section of at least 10 mm² for all power connections. An externally accessible emergency stop switch must be installed and fully functional before commissioning. The converter is rated for a maximum operating temperature of 50 °C and exhibits a power loss of 6.5 kW under full load. Its enclosure meets the 3K3 environmental class per DIN IEC 721-3-3, ensuring protection against airborne contaminants and excessive humidity.

Commissioning is simplified by an integrated operator panel with a graphical display and guided prompts, while a durable type plate provides key certification, voltage, current, and frequency ratings. Firmware is supplied as a separate subitem to guarantee traceable version control. The RD52.1-4N-200-F-V1-FW ships with a one-year warranty and must be used in its original configuration without structural modifications. Its robust design and clear mounting instructions make it an ideal choice for heavy-duty conveyor systems, pump drives, and precision motion control applications.
