Product Description

The Bosch Rexroth RD52.1-4B-015-L-NN-FW is a three-phase drive system. The rated output with 380 to 480 Volts AC input is 15 kilowatts. The drive output with 200 to 230 Volts AC input is 7.5 kilowatts. The converter on the RD52.1-4B-015-L-NN-FW includes a built-in brake chopper. The drive can be operated with three different pulse frequencies that are 4 kilohertz, 8 kilohertz and 12 kilohertz. The performance ratings vary with the configured pulse frequencies. At 4 kilohertz, the motor output is 15 kilowatts, the output frequency range is 0 to 250 Hertz, the rated output current is 30 Amps, the peak current is 39 Amps for 60 seconds, and the rated output power is 20 kVA. At 8 kilohertz, the motor output is 11 kilowatts, the output frequency range is 0 to 500 Hertz, the rated output current is 25 Amps, the peak current is 33 Amps for 60 seconds, and the rated output power is 16 kVA.

At 12 kilohertz, the output frequency range is 0 to 1400 Hertz, the rated output current is 18 Amps, the peak current is 23 Amps for 60 seconds, and the rated output power is 12 kVA. The performance ratings for the brake chopper on the RD52.1-4B-015-L-NN-FW include 7.5 kilowatts continuous power, and 37 kilowatts peak power. The cooling method for the RD52.1-4B-015-L-NN-FW is forced air cooling. This cooling method requires the operation of fans or blowers to force air across the heated surface of the RD52.1-4B-015-L-NN-FW drive. Bosch has recommended a minimum air flow rate of 0.05 cubic meters per second. If this air flow rate is not ensured, then the ambient temperature could exceed permitted limits, which could cause performance derating and even device malfunction.
