RD52.2-4B-018-L-A1-FW

The Bosch Rexroth Indramat RD52.2-4B-018-L-A1-FW from the RD 500 Drive Controllers series combines robust power conversion and precise automation control in a single compact unit. With a nominal connecting voltage of 3 × AC 380-480 V and a rated power of 18.5 kW, this converter meets the demands of high-performance industrial drives. Its forced air cooling mechanism ensures continuous thermal management, while the converter with a built-in brake chopper topology provides integrated protection against regenerative overcurrents. Engineered for global applications, the RD52.2 model is built to rigorous quality standards, guaranteeing reliability and ease of integration.

Efficiency and processing capability are paramount: this controller maintains up to 95 % efficiency under nominal loads and leverages a 32-bit floating-point signal processor for advanced control algorithms and rapid response to dynamic motor demands. The device operates at a rated current of 35 A and can withstand short-term peaks up to 46 A for 60 s without derating, ensuring resilience under transient loads. Flexible connectivity is achieved through dedicated power cables for drive input and motor feedback cables for high-speed data exchange, streamlining installation and commissioning in complex machine environments. The broad 380–480 V operating range accommodates regional voltage variances, reducing the need for external transformers or voltage converters.

Safety and maintenance are built in: the integrated brake chopper protects the power stage from deceleration energy spikes, minimizing the risk of damage to power semiconductors and extending service life. A standard one-year warranty supports global deployment and simplifies lifecycle management, backed by Bosch Rexroth Indramat’s extensive service network. Compact yet powerful, the RD52.2-4B-018-L-A1-FW AC drive converter is ideally suited for applications in packaging, material handling, and precision motion control where reliability and performance are non-negotiable.
