Product Description

The highly functional RD 500 drive system by Bosch Rexroth is a universal, three-phase system used for synchronous and induction motors. It features a modular design that allows its components to be freely combinable to suit a wide variety of applications. These components include inverters for DC connections, frequency converters, rectifier, and supply modules. They are used in machine tools, textile machines, printing and packaging machinery, robotics, and handling machines.

The RD52.1-8N-075-L-L1-FW is a drive inverter for DC supply in Bosch Rexroth’s RD 500 drive system. This model uses the field-oriented control for its operation and a nominal connecting voltage of 700V with a tolerance of ±10%. Its rated power output is 75kW, and this is the maximum permissible motor power based on a 4-pin standard induction motor. Its output frequency ranges up to 1,400Hz, depending on the pulse frequency that is used for its operation. The inverter belongs to Size Class D and has an Ingress Protection rating of IP 20 according to EN 60529 without its connection terminals.

The cooling of the RD52.1-8N-075-L-L1-FW is by forced air cooling. It is equipped with a 24V standby power supply that permits its operation when it is not connected to any line supply voltage supply. Some of the functions that can be performed with the additional supply voltage are the reading and parameterization of data sets and the continuous operation of field buses. The compact design of this inverter supports its mounting in control cabinets with its supply unit. The control cabinet has an IP 10 protection rating, meaning that it is touchproof, dustproof, and impenetrable to solid extrinsic objects larger than 50mm. This product can be shipped globally with a one year warranty period from Wake Industrial.
