RD52.1-4N-160-R-NN-FW/S149

The Bosch Rexroth Indramat RD52.1-4N-160-R-NN-FW/S149 from the RD 500 Drive Controllers series operates with a nominal connecting voltage of 3 x AC 380-480 V and delivers a rated power of 160 kW. This converter without a built-in brake chopper utilizes liquid cooling with internal pump to maintain optimal thermal performance in demanding applications. Designed for three-phase AC motor control, it supports a 170% overload for 1 second and features a compact size class G housing. Built to IP20 standards, the drive balances high power density with robust protection.

At a pulse frequency of 4 kHz, the RD52.1-4N-160-R-NN-FW/S149 provides a motor output of 160 kW across an output frequency range of 0 to 150 Hz. The drive sustains a rated current of 290 A and a peak current of 377 A for 60 seconds, delivering a rated drive output of 191 kVA and a peak drive output of 248 kVA under transient conditions. Power loss is limited to 6.5 kW at this switching rate, ensuring efficient energy conversion under continuous operation.

When switched to 8 kHz pulse frequency, the unit adjusts to a motor output of 132 kW with a rated current of 230 A and a 60-second peak current of 299 A. The corresponding rated drive output is 151 kVA with a peak of 197 kVA, and power loss drops to 5.2 kW for improved efficiency at higher switching speeds. Encased in an IP20 frame weighing approximately 157 kg, the RD52.1-4N-160-R-NN-FW/S149 offers reliable performance and global shipment readiness backed by a one-year warranty from Wake Industrial.
