Product Description

The Bosch RD51.1-4B-022-L-F1-FW is a 3-phase drive system. It is designed for motor control in industrial control applications. The power section on the drive is designed for cooling at the rear. Therefore the forced air cooling can be achieved with higher degree of protection. The drive can be programmed and parameterized through multiple options including the optional operator panel or the high-performance RDwin software which installs and runs on a PC. To prevent feedback of harmonics to the line supply, the RD51.1-4B-022-L-F1-FW comes with radio interference suppression filters that are integrated into the AC drive converter. The converter on the drive is rated for 3-phase input at 380 to 480 Volts AC. The permitted tolerance for input voltage is ±10%. The converter includes an integrated brake chopper. An additional function supported by the drive is feedback of current filter. Firmware for the drive system needs to be ordered as a separate subposition.

Output power rating of the RD51.1-4B-022-L-F1-FW is 22 kilowatts. Weight of the drive system is 36 kilograms. The drive enclosure belongs to the IP 20 protection class. The drive is designed for indoor use and should be installed inside a suitable switch cabinet where it will be protected from dust and moisture. Performance data for the chopper on the drive converter include 14 kilowatts continuous power, 56 kilowatts peak power for 1 seconds and minimum resistance value of 11.7 Ohms. During drive operation, the temperature of air which surround the drive should be kept between 0 and 40 degrees Celsius. The cooling air requirement specified by Bosch is 0.1 cubic meters per second. Qualified and trained technical personnel should handle, install, and operate the RD51.1-4B-022-L-F1-FW drive system. This product can be shipped globally with a one year warranty period from Wake Industrial.
