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

The Bosch Rexroth Indramat RD52.1-4B-160-R-V1-FW from the RD 500 Drive Controllers series delivers high-performance AC drive conversion with a Nominal Connecting Voltage 3 x AC 380-480 V and a Rated Power 160 kW output. This Converter with a built-in brake chopper employs liquid cooling with internal pump to maintain optimal thermal stability under continuous loads. Housed in a robust enclosure engineered for industrial use, it integrates seamlessly into existing power networks. The design prioritizes reliability and precision control for demanding applications.

The drive features an Overload Capability of 170% for 1 second to handle transient loads with confidence. It supports three selectable Pulse Frequencies: 12 kHz, 8 kHz, and 4 kHz to balance switching losses and dynamic response. At 12 kHz, the unit delivers a Rated Current of 170 A, a Peak Current of 221 A, and a Rated Output of 112 kVA. When switched to 8 kHz and 4 kHz, it increases performance to 230 A rated/299 A peak (151 kVA) and 290 A rated/377 A peak (191 kVA) respectively.

Commissioning is facilitated through Bosch Rexroth’s PC-based RDwin Software or via an optional control panel, enabling rapid setup and parameterization. The drive supports 24 V standby power through an external supply, ensuring control logic remains active during main power interruptions. Firmware modules are ordered separately to tailor feature sets, and each unit ships with a type label specifying ratings and firmware codes. Wake Industrial backs this product with a one-year global warranty for peace of mind in mission-critical deployment.
