The R911201009 (RD51.2-4B-003-L-A1-FW) is a Bosch Rexroth RD series three-phase drive controller designed for motor control applications. It is equipped with a built-in brake chopper and supports input voltages from 380 to 480 V AC ±10%. At a 4 kHz pulse frequency, it delivers a rated output power of 3 kW, output frequency range of 0 to 250 Hz, rated current of 7.5 A, and peak current of 13 A for 1 second, with a rated output of 4.9 kVA. Increasing the pulse frequency to 8 kHz reduces output power to 2.2 kW. The device supports forced air cooling, requiring a minimum airflow of 0.03 m³/s, and features filter current feedback, starting lockout, and stand-by power capability with an external 24 V DC supply.
