The Bosch Rexroth R911201261 (RD51.1-5N-030-L-NN-FW) is part of the RD500 series and acts as a vector control device converter unit, operating at a nominal voltage of 3 x 500 V AC ± 10%. It boasts wide-ranging applications in fields such as transmission technology, assembly systems, and machine tools, particularly when used with compatible drive systems. Key specifications include a built-in brake chopper with a minimum resistance of 8.8 ohm, a continuous power of 19 kW, and a peak power of 74 kW at varying Pulse Width Modulation (PWM) frequencies. The unit's 58 kVA peak power for a minute changes based on the chosen PWM frequency. Temperature regulation is achieved via a forced air-cooling mechanism. The unit has an Ingress Protection (IP) rating of 20 and falls under the C size class. Most suitable for industrial applications, the R911201261 (RD51.1-5N-030-L-NN-FW) needs pre-commissioning programming and operates best at 0-40 degrees Celsius. It comes with a global one-year warranty provided by Indramat USA.
