Product Description

The Bosch RD51.1-4B-015-L-V1-FW is a universal drive system. It is designed for three-phase AC input. The range of input voltages supported by the drive are 380 to 480 Volts AC. At rated input the drive delivers 15 kilowatts output. The RD51.1-4B-015-L-V1-FW also operates at AC input voltages ranging from 200 to 230 Volts AC. However at this input range the output of the drive falls to 7.5 kilowatts. The drive is based on a converter with integrated brake chopper. The drive can be operated at multiple pulse frequencies. At 4 kilohertz pulse, the rated motor output is 15 kilowatts, the output frequency range is 0 to 250 Hertz, the output current is 30 Amps, the peak output current is 60 Amps for 0.5 seconds, and the rated apparent power output is 20 kVA.

At 8 kilohertz pulse, the rated motor output is 11 kilowatts, the output frequency range is 0 to 500 Hertz, the output current is 25 Amps, the peak output current is 50 Amps for 0.5 seconds, and the rated apparent power output is 16 kVA. The weight of the RD51.1-4B-015-L-V1-FW drive is 11.3 kilograms. Bosch has designed the RD51.1-4B-015-L-V1-FW for forced air cooling which relies on fans or blowers for increasing the rate of air flow across operating devices. The optimal temperature range for drive operation is 0 to 40 degrees Celsius. The continuous power output of the brake chopper is 7.5 kilowatts and the peak power output is 37 kilowatts for 1 second. RD51 drives supports various additional functions. The addition function supported by the RD51.1-4B-015-L-V1-FW is 24 Volts standby power. This feature requires connection of an external 24 Volts DC supply to the drive system. This product can be shipped globally with a one year warranty period from Wake Industrial.
