Product Description

The Bosch RD51.1-7N-022-L-NN-FW is a 22 kilowatts rated universal drive controller that relies on forced air cooling for heat dissipation. The housing of the controller belongs to the IP20 protection category. This protection category does not provide any protection against ingress of liquid contaminants. For improved environmental protection, the drive controller has to be mounted inside a suitable control cabinet. The RD51.1-7N-022-L-NN-FW is designed for 0 to 40 degrees Celsius ambient temperature. Higher ambient temperatures cause the output of the drive to derate. Forced air cooling relies on fans and blowers for increasing air flow across the surface of the heated controller. The minimum air flow rated specified by Bosch for proper cooling of the drive is 0.1 cubic meters per second. The approximate shipping weight of the drive controller is 22 kilograms.

The inverter on the RD51.1-7N-022-L-NN-FW operates at 530 to 670 Volts DC. The motor output and current output at 4 kilohertz pulse are 22 kilowatts and 43 Amps respectively. The motor output and current output at 8 kilohertz pulse are 18.5 kilowatts and 35 Amps respectively. The RD51.1-7N-022-L-NN-FW is designed for industrial applications that include chemical and process technology, machine tools, handling and assembly systems and packing machines. Several additions functions are available for RD51 drives. However Bosch has not provided additional functions on the RD51.1-7N-022-L-NN-FW drive. The drive unit should only be operated under the specified mounting and installation conditions, in the specified mounting position and under the specified ambient conditions. Moreover the RD51.1-7N-022-L-NN-FW should only be used for approved applications. Bosch will not be liable for any damages caused by improper use of the drive or its use for non-approved applications. This product can be shipped globally with a one year warranty period from Wake Industrial.
