Product Description

The RD51.1-4B-037-L-D1-FW is a Bosch Rexroth universal drive controller. The product line to which it belongs is the REFUDrive RD50 family.

The input rating for the converter on the RD51.1-4B-037-L-D1-FW is 380 to 480 Volts AC (three-phase). The drive can also be operated at 200 to 230 Volts AC input, but doing so results in output derating. The nominal output of the drive is 37 kilowatts, which is available with the rated input and 4 kilohertz pulse frequency. The current output of the RD51.1-4B-037-L-D1-FW at 4 kilohertz is 82 Amps and rated apparent power output is 54 kVA. The drive output at 8 kilohertz pulse frequency is 30 kilowatts, the current output is 56 Amps and the rated apparent power output is 37 kVA.

The RD51.1-4B-037-L-D1-FW drive supports two additional functions which are 24 Volts standby power and connection for RZC01.1-XT with NAMUR terminal strip. The RZC series devices are chemistry modules which are available as accessories for RD51 drives and enhance drive functionality for applications involving chemical processes. The continuous power rating of the brake chopper on the RD51.1-4B-037-L-D1-FW is 23 kilowatts and its peak power rating is 93 kilowatts. The RD51.1-4B-037-L-D1-FW cools via forced air cooling and requires 0.2 m³/s of air flow. Weight of the RD51.1-4B-037-L-D1-FW drive is 36 kilograms.
