Product Description

The Bosch Rexroth RD52.1-7N-055-L-V1-FW is a universal drive controller. It is part of the RD52 series which is designed for control of induction and synchronous motors. RD52 drives features a modular architecture that allows drive adaptation to a wide range of industrial applications. The RD52.1-7N-055-L-V1-FW is based on an inverter that works with DC supplies over the 530 to 670 Volts DC range. Up to ±10% input voltage tolerance is supported by the drive input. The inverter on the RD52.1-7N-055-L-V1-FW does not include a brake chopper. RD52 drives with integrated brake choppers are available and can be ordered if required. The rated output of the RD52.1-7N-055-L-V1-FW is 55 kilowatts at 4 kilohertz pulse frequency. Additional drive specifications for 4 kilohertz pulse include 0 to 250 Hertz output frequency, 99 Amps rated current and 168 Amps peak current for 1 second.

The rated motor output of the RD52.1-7N-055-L-V1-FW at 8 kilohertz is 45 kilowatts. Additional drive specifications for 8 kilohertz pulse include 0 to 500 Hertz output frequency, 82 Amps rated current and 139 Amps peak current for 1 second. The RD52.1-7N-055-L-V1-FW drive is designed for forced air cooling. Bosch has recommended a minimum air flow rate of 0.4 cubic meters per second. If the air flow rate falls below this threshold, then the internal temperature of the drive could reach levels that could cause components to malfunction or even fail. The size class of the drive is D and its protection rating is IP20.  Multiple optional features can be ordered for RD52 drive. The RD52.1-7N-055-L-V1-FW supports one additional function which is 24 V stand by power. Qualified and experienced professional should be tasked with operation and maintenance of the unit. This product can be shipped globally with a one year warranty period from Wake Industrial.
