RD52.1-4N-160-R-V1-FW

The RD52.1-4N-160-R-V1-FW from Bosch Rexroth Indramat is part of the RD 500 Drive Controllers and serves as a high-performance AC drive converter. It operates on a Nominal Connecting Voltage of 3 x AC 380-480 V, ±10% to deliver a Rated Power of 160 kW. As a Converter without a built-in brake chopper, it leverages advanced field-oriented regulation for precise motor control. The unit features liquid cooling with internal pump to maintain optimal thermal stability under continuous load.

This converter weighs 157 kg and occupies the Size Class G chassis with a robust IP20 Protection Degree housing. It meets Environmental Class 3K3 standards for ambient operation from 0 – 40 °C with a 50% power reduction at 2.5% per Kelvin above rated temperature. The drive requires a Cooling Air Requirement of 0.4 m³/s and exhibits a Power Loss of 6.5 kW during normal operation. On the output side, the unit supports a PWM Frequency of 4 kHz and an Output Frequency range of 0 – 150 Hz. It delivers a continuous current rating of 290 A and sustains a peak current of 377 A at T=60 s, while providing an apparent power of 191 kVA.

Integration of the RD52.1-4N-160-R-V1-FW into drive systems is streamlined through standard connectivity for sensors and actuators, enabling turnkey implementation in automation and process industries. Its liquid-cooled design ensures high reliability and reduced maintenance compared to fan-cooled units, even in dusty or humid environments. Backed by a global one-year warranty, this drive controller delivers consistent performance and durability in demanding applications such as conveyor systems, extrusion lines, or heavy-duty machine tools.
