RD52.1-5B-075-L-F1-FW

The Bosch Rexroth Indramat RD52.1-5B-075-L-F1-FW drive converter is part of the RD 500 Drive Controllers series, offering advanced motion control for industrial applications. Manufactured by Bosch Rexroth Indramat, this unit operates on a Nominal Connecting Voltage of 3 x AC 500 V and delivers a Rated Power of 75 kW through its integrated power electronics. Featuring forced air cooling, the converter maintains optimal operating temperatures, ensuring reliable performance. Its primary function is to convert and regulate AC input into a variable-frequency output for precise motor control in manufacturing processes.

This AC Drive Converter supports a wide frequency modulation range, adjusting input frequency from 50–60 Hz to 0–500 Hz to match application requirements. The built-in brake chopper handles regenerative energy with a continuous power dissipation capacity of 45 kW and a peak of 148 kW, using a minimum resistance of 4.4 Ω. The drive operates at switching frequencies of 4/8 kHz, drawing continuous currents of 108 A and 80 A respectively. A dedicated blower unit provides forced air circulation to dissipate heat under full load, allowing operation in ambient temperatures from 0 to +40 °C without derating and at altitudes up to 1,000 meters above sea level.

Designed for seamless integration, the RD52.1-5B-075-L-F1-FW features an IP20 enclosure rating and must be installed within an IP54-rated control cabinet to ensure environmental protection. Weighing approximately 52 kg (excluding mounting hardware), it offers a compact footprint for space-constrained panels. The converter includes current filter feedback for stable operation and requires firmware configuration to suit specific drive profiles. With compliance to industrial protection standards and a one-year warranty, this robust converter enhances system efficiency, reduces downtime, and ensures consistent torque delivery in demanding applications.
