Product Description

The Bosch Rexroth RS51.1-4G-050-V-NN-FW is a REFUdrive 500 series AC drive. It is a drive system designed for motor control applications. The drive features modular hardware and software that enables adaptation to different requirements. The power section on the RS51.1-4G-050-V-NN-FW is designed for cooling at the rear. The units can also be forced ventilated outside the cabinet with a high degree of protection. The RS51.1-4G-050-V-NN-FW can be configured through an operator panel or from a PC running the REFUwin software package. The drive supports integrated radio interference suppression filter and a line reactor for harmonic suppression. A rating plate is attached to the drive: in addition to type code and firmware version, it enables easy identification of drive input and output parameters. The nominal connecting voltage for the RS51.1-4G-050-V-NN-FW is 380 to 480 Volts AC (three-phase).

The RS51.1-4G-050-V-NN-FW drive features an integrated brake chopper and resistor. The output power rating of the drive is 50 kVA. The output frequency range is 0 to 1000 Hertz. The nominal drive current is 66 Amps and the rated current is 83 Amps. Peak output power for the RS51.1-4G-050-V-NN-FW is 63 kVA for 60 seconds. Environmental class of the RS51.1-4G-050-V-NN-FW drive is 3K3 as per DIN IEC 721-3-3. The cooling airflow requirement is 0.4 cubic meters per second. The drive output will derate and it could also malfunction if this required level of airflow is not maintained. The ideal ambient temperature is 0 to 40 degrees Celsius. The IP20 rated drive weighs approximately 80 kilograms. The drive should be stored in a clean and dry environment where the temperature of surrounding air is maintained between -25 and 70 degrees Celsius. This product can be shipped globally with a one year warranty period from Wake Industrial.
