Product Description

Bosch Rexroth is a well-reputed developer of industrial automation products such as power tools (hand-cutters, grinders, drills, etc.), industrial PCs, heavy-duty servo motors, and accessories.

The RD52.1-4B-045-L-NN-FW model firmware is not included in the package and needs to be ordered separately. The RD52.1 drive converter is rated to be used with a 3 x AC 380 - 480 V power supply from a recommended supply unit. The module generates heat during operation which can be discharged through a cooling fan or blower. For effective cooling, leave a sufficient gap between devices, if installed in a group. The alphabet ‘B’ in the type code represents the built-in brake chopper for effective and safe braking during operation. The drive converter is designed for a three-phase synchronous or induction motor. The rated motor output is 45 kW with a frequency of 0 - 250 Hz. The module uses a rated current of 82A and a peaks current of 107A for 60 seconds. The converter module is capable of operating at 139A for 1 second and 164A for 0.5 seconds. The RD52.1 drive converter operates to provide peak power of 70 kVA for one minute and a rated output of 54 kVA during continuous operation.

The model RD52.1-4B-045-L-NN-FW is safe to be operated in an environment with a maintained temperature between 0 and +40 degree Celsius. The cooling air requirement for the model is 0.2 cubic meters per second. The device (RD52.1-4B-045-L-NN-FW) is protected from unnecessary radio signal interference and noise immunity with A1 class specifications. The weight of the converter is 36 kg and should be handled with extreme care. The brake choppers perform to provide a continuous power of 27 kW and a peak power of 111 kW for 1 second. The minimum resistance value of the built-in brake chopper is 5.8 Ohm. This product can be shipped globally with a one year warranty period from Wake Industrial.
