Product Description

The Bosch Rexroth RD51.1-8N-045-L-V1-FW is a state-of-the-art three-phase drive system. It can be used for control of induction and synchronous motors. The RD51.1-8N-045-L-V1-FW features a DC inverter rated for 700 Volts DC (±10%). Brake chopper is not available on the system. The rated nominal power output of the drive system is 45 kilowatts. Additional function supported by the system is 24 Volts stand-by power (external). This feature requires a 24 Volts DC control power supply and enables the control electronics on the RD51.1-8N-045-L-V1-FW to operate in the absence of line supply voltage. Advantages offered by the stand-by power feature include the ability to parameterize data sets in the absence of line supply voltages and DC link voltages. To prevent ground loops, Bosch recommends connecting the 24 Volts standby power to the X83 in a floating manner.

At 700 Volts DC, the output frequency range of the RD51.1-8N-045-L-V1-FW is 0 to 250 Hertz, the rated current is 66 Amps, the peak current for 60 seconds is 86 Amps, the peak current for 1 second is 112 Amps, the peak current for 0.5 seconds is 132 Amps, the rated output power is 54 kVA and the peak output power for 60 seconds is 71 kVA. Forced air cooling is required to keep the ambient temperature around the RD51.1-8N-045-L-V1-FW within the permitted range and requires 0.2 cubic meters of airflow. The weight of the RD51.1-8N-045-L-V1-FW drive system is 22 kilograms. Ingress protection class of the system is IP20 which means that it is protected against solid objects measuring up to 12 millimeters (such as human fingers) but is not protected against water ingress. Therefore the drive system has to be installed inside a cabinet. This product can be shipped globally with a one year warranty period from Wake Industrial.
