RD52.1-4N-001-D-NN-FW

The RD52.1-4N-001-D-NN-FW by Bosch Rexroth Indramat joins the robust RD 500 Drive Controllers family, offering precise AC drive control in a compact footprint. Engineered for demanding industrial environments, this converter adapts seamlessly to three-phase mains and delivers consistent performance. Built on Rexroth's legacy of innovation, the RD52.1 model benefits from proven hardware and software integration. Its plug-through cooler mechanism enhances thermal management without external fans, ensuring sustained uptime even under heavy loads.

Incorporating a Nominal Connecting Voltage of 3 x AC 380-480 V, the unit provides Rated Power of 1 kW to support a Rated Motor Output of 1.5 kW at 400 V and 500 V, and up to 2 kW at 460 V. The converter sustains a Rated Current of 4 A and handles Peak Currents of 5.2 A for 60 s, 6.8 A for 1 s, and 8 A for 0.5 s. With an overall Unit Type defined as a converter without a built-in brake chopper, it integrates an internal line filter for EMC compliance, minimizing noise emissions. Its Dimensions of 90 mm (W) x 560 mm (H) x 200 mm (D) and Weight of 15 kg facilitate installation in space-constrained panels.

Designed for modular assembly, the RD52.1's bottom-to-top airflow and plug-through cooler deliver dependable cooling even in high-humidity or dusty plant floors. A removable operator panel allows rapid parameter loading and local diagnostics without disassembly. With Bosch Rexroth's global support network, this drive converter ensures minimal downtime and streamlined commissioning, making it ideal for packaging machines, conveyors, and multi-axis motion systems.
