The R911200549 (RD51.1-4N-055-L-D1-FW) is a high-performance 3-phase drive converter designed for inductor/synchronous motors, manufactured by Bosch Rexroth. Rated at 99 Amperes under a supply voltage rating and 4 kHz PWM frequency, it has the capacity to operate at 8 kHz and 12 kHz with differing specifications. Its optimal operation requires a relative humidity below 90% and ambient temperature between 0 - 40 degrees C, minus any electrically conductive or aggressive gases. Heat emissions necessitate distance from heat-sensitive objects and equipment, whilst storage requires a dry, clean environment with -25 - 70 degrees C ambient temperature. Featuring an aluminium-Elko direct current (DC) link capacitors, it is designed for straightforward commissioning and user-friendliness. The R911200549 (RD51.1-4N-055-L-D1-FW) can be stored for two years under zero voltage conditions, needing capacitor reformation if stored longer. All key information is listed on its rating plate, with a one-year warranty offered by Indramat USA.
