RD52.2-4B-007-L-A2-FW/S133

The Bosch Rexroth Indramat RD52.2-4B-007-L-A2-FW/S133 belongs to the RD 500 Drive Controllers series and combines precision control with robust design. This converter with a built-in brake chopper operates on a nominal connecting voltage of 3 x AC 380-480 V and delivers a rated power of 7.5 kW, enabling reliable performance for synchronous and induction motors. The device employs forced air cooling to maintain optimal internal temperatures, while its compact housing meets IP20 protection class requirements. Designed for streamlined integration into existing automation architectures, this controller ensures predictable motor behavior and efficient power management.

Built around a high-performance brake chopper, the RD52.2-4B-007-L-A2-FW/S133 offers a continuous braking power of 3.8 kW and a peak power of 18 kW for up to one second, supported by a minimum resistor value of 35 Ω to manage regenerated energy. The unit is engineered to operate within an ambient temperature range of 0 °C to 40 °C and up to 90 % relative humidity (non-condensing) under the specifications of the 3K3 environmental class. With a cooling air requirement of 0.03 m3/s of contaminant-free airflow, the blower-driven ventilation system ensures consistent thermal dissipation even under continuous duty cycles. These features combine to deliver safe, durable operation in demanding industrial settings.

Installation and commissioning are straightforward, with a standardized housing form factor and clear electrical interfaces for rapid field configuration. The RD52.2-4B-007-L-A2-FW/S133 must be installed by qualified personnel and configured prior to first use to guarantee performance and longevity. Firmware for this drive controller is available separately to align with specific application requirements. Supported across chemical processing, conveyor systems, packaging equipment, and material handling machinery, this drive converter represents a versatile solution for modern automation challenges.
