The Bosch Rexroth Indramat RD52.2-5B-015-L-A2-FW from the RD 500 Drive Controllers series is a high-performance Converter with a built-in brake chopper engineered for demanding industrial applications. This AC drive converter operates at a Nominal Connecting Voltage of 3 x AC 500 V with a tolerance of ±10%, delivering a continuous Rated Power of 15 kW. It features a robust forced air cooling mechanism to ensure reliable thermal management under heavy loads. The unit complies with EMC directives per EN 50082-2 for both noise emission and immunity, making it ideal for sensitive automation environments.
The RD52.2-5B-015-L-A2-FW is rated for a 20 A Rated Current at an 8 kHz Pulse Frequency, enabling precise motor control and smooth torque delivery. Enclosed to IP20 Protection in accordance with EN 60529, the drive converter safeguards internal electronics from accidental contact and debris. Built-in safety features include a full brake chopper circuit and fault diagnostics to minimize downtime. Its electronic modules are serviceable only when necessary, and a mandatory 30-minute cooldown period before access ensures operator safety.
Weighing just 11.3 kg, this converter remains compact for efficient cabinet integration, yet rugged enough for assembly and handling systems. It incorporates AL electrolytic capacitors as DC link storage elements, which can be stored without power for up to two years at ≤40 °C without performance degradation. With global delivery and support, the RD52.2-5B-015-L-A2-FW offers a balanced combination of power density, precision control, and long-term reliability.
