The product in focus is the Bosch Rexroth Indramat RD 500 series R911288926 (RD51.1-4N-005-L-V1-P1-NN-FW), a converter type drive control system. It operates on a nominal voltage of 380 - 480 volts with a ±10% tolerance level and comes in wide-ranging industrial applications. The system offers varying performance at 4kHz and 8kHz frequencies, compliant with the 3K3 climatic category and has an Ingress Protection class of 20. The rated current and output power differ between the two frequency settings, with a higher output at 4kHz. The weight stands at approximately 6.5kg, and it employs a PROFIBUS-DP interface for efficient control and supervision of electric motors. Powered by external 24 volts, the R911288926 (RD51.1-4N-005-L-V1-P1-NN-FW) uses forced convection for cooling. Due to its high voltage, trained technicians should install, operate, and maintain it. The product comes with a cross-continental shipping offer and a one-year warranty from Indramat USA.
