The R911200548 (RD51.1-4B-055-L-D1-FW) is a converter from the Indramat Refu RD 500 drive system, engineered for three-phase AC input (380–480 V, ±10%) and supporting a 55 kW rated output. This module enables control of both synchronous and induction motors using pulse-width modulated output voltage and high-speed semiconductor switching. It includes an integrated brake chopper, forced air cooling, and basic line features such as U/f curve control, plus built-in filters for radio interference suppression and line reactors to limit harmonic feedback. The design features IP20 protection per EN 60529, a maximum ambient operating temperature of 40°C, and accommodates connection for RZC01.1-XT with NAMUR terminal strip and 24 V standby power.
