RD52.3-8C-160-R-MV-FW

The Bosch Rexroth Indramat RD52.3-8C-160-R-MV-FW from the RD 500 Drive Controllers series is a high-performance inverter operating as RD52 SFT with a nominal connecting voltage of DC 700 V (+/–10%). It delivers a rated power of 160 kW and features robust liquid cooling with internal pump to manage thermal loads under continuous operation. Manufactured to design code 3, this drive control integrates advanced sinus frontend technology for regenerative energy recovery. Installation requires careful separation of signal, power, motor, and line supply cables by a clearance distance of at least 20 cm to ensure optimal electromagnetic compatibility.

Reliability is further assured through an environmental class 3K3 rating per DIN IEC 721-3-3, protecting against dust and moisture. The unit supports a maximum output of 205 kVA at 4 kHz pulse frequency and accommodates AWG 24 to AWG 12 cable cross-sections for control voltage connections. Filter feedback is implemented via its dedicated X2 connector, while a flush filter connection to the cabinet housing and a high-quality radio interference suppression filter placed close to noise sources minimize EMI. The drive is supplied in custom military-grade packaging and includes a one-year warranty for complete peace of mind.

Auxiliary systems include fans powered by 220 V/230 V supplies and a specified cooling air requirement of 0.4 m3/s to maintain internal temperatures below critical levels. Operators must observe that hot components can exceed 30 °C and may cause burns if handled improperly. For installations using a central DC supply, the fans and control electronics must be electrically isolated from the main DC link. Proper cable routing along grounded sheet steel panels further reduces noise coupling and enhances overall system stability.
