The R911200320 (RD52.1-4B-315-F-W1-FW) is a Bosch Rexroth RD52.1 series drive converter designed for applications requiring high power output and robust design. It supports a rated power output of 315 kW at a rated current of 540 A, with a short-term overload capability of 702 A for 60 seconds and 918 A for one second. The converter operates at a nominal connecting voltage of 3 x AC 380-480 V. Dimensions are 1510 mm x 980 mm x 380 mm with a mass of 358 kg. It uses forced air cooling with integrated liquid circulation, and features a built-in brake chopper rated at 280 kW peak power and a resistor limit of 1.1 Ω. The unit is modular, allowing targeted component replacement, and includes provisions for RC elements and diodes to suppress noise on supplementary components. Firmware must be sourced separately.
