Product Description

The Bosch Rexroth RD52.1-4N-160-R-NN-FW/S149 is a three-phase drive system. It is designed for the management and control of various synchronous and induction motors. Technical characteristics of RD52 series devices include graphical display, AC or DC supply, multiple cooling modes including forced air, conducting plate of liquid cooling, support for multiple interfaces and support for Synchlink. RD52 series drives such as the RD52.1-4N-160-R-NN-FW/S149 can handle up to 170% overload for 1 second. Two pulse frequencies are supported by the RD52.1-4N-160-R-NN-FW/S149 that are 4 kilohertz and 8 kilohertz. The performance specifications for the drive vary with the pulse frequency. At 4 kilohertz, the RD52.1-4N-160-R-NN-FW/S149 is rated for 160 kilowatts motor output. The output frequency range is 0 to 150 Hertz, the rated current is 290 Amps, the peak current for 60 seconds is 377 Amps, the rated drive output is 191 kVA and the peak power for 60 seconds is 248 kVA.

At 8 kilohertz pulse frequency, the RD52.1-4N-160-R-NN-FW/S149 is rated for 132 kilowatts motor output. The rated current is 230 Amps, the peak current for 60 seconds is 299 Amps, the rated output is 151 kVA and the peak power for 60 seconds is 197 kVA. The RD52.1-4N-160-R-NN-FW/S149 features a converter and can be connected to AC input at 400 to 480 Volts AC. The drive cools through circulation of a liquid coolant and features a pump for driving the coolant circulation. Brake chopper is not available on the drive converter. The power loss at 4 kilohertz is 6.5 kilowatts and at 8 kilohertz the power loss is 5.2 kilowatts. Size class of the drive system is G and the housing is IP 20 rated. The approximate weight of the drive is 157 kilograms. This product can be shipped globally with a one year warranty period from Wake Industrial.
