Product Description

The RD51.1-4B-055-L-C1-FW is a 55 kilowatts rated drive controller. It is developed by Bosch Rexroth for industrial applications. The controller supports two additional functions: connection for RZC01.1-XN and 24 Volts standby power. RZC series devices are chemistry modules that are available as accessories for Bosch controller. Chemistry modules can enhance drive functionality for the chemical and process industries. The standby power feature allows parameterization of the RD51.1-4B-055-L-C1-FW controller when the main supply is disconnected. It also allows the control electronics to function when the main supply is disconnected. However the standby power feature does requires an external power supply that delivers 24 Volts DC to the controller. The RD51.1-4B-055-L-C1-FW cools via forced air cooling. The minimum rate of flow recommended by Bosch for drive cooling is 0.4 m³/s. Fans and blowers can be used to provide this minimum rate of air flow.

The optimal ambient temperature for controller operation is 0 to 40 degrees Celsius. If the ambient temperature exceeds recommended values then the internal temperature of the RD51.1-4B-055-L-C1-FW could rise to dangerous levels and could cause component malfunction or even failure. The RD51.1-4B-055-L-C1-FW is based a converter rated for three-phase 380 to 480 Volts AC input The converter includes an integrated brake chopper. The overload capability for the RD51.1-4B-055-L-C1-FW is 200% overload for 0.5 second and 170% overload for 1 second. A type label is attached to the RD51.1-4B-055-L-C1-FW and it lists important information including the type code, the firmware type code, the serial number, and the input and output current and voltage ratings. The type label is provided for device identification. It should be checked at the time of equipment delivery. The controller should only be installed by qualified personnel. This product can be shipped globally with a one year warranty period from Wake Industrial.
