Product Description

The RD51.1-5B-055-D-D1-FW is a field-oriented vector control device from Bosch Rexroth's RD500 series. It is a converter unit type and 3 x 500 V AC ± 10% as its nominal connecting voltage. Conveyor technology, assembly systems, and machine tools are some of the unit's industrial applications. When used in conjunction with compatible drive systems, the RD51.1-5B-055-D-D1-FW has a wide range of applications. This unit has a built-in brake chopper with a continuous power of 33 kW and minimum resistance of 5 Ohms at a PWM frequency of 4 kHz.

The RD51.1-5B-055-D-D1-FW's maximum rated power output is 55 kW, but it varies depending on the pulse (PWM) frequency at which the device is used. For example, rated power at 4 kHz is 55 kW, while rated power at 8 kHz is 45 kW. A plug-through heat extraction mechanism is used to keep the RD51.1-5B-055-D-D1-FW cool, and it is equipped with an additional function. Its rated current at 4 kHz is 80 A and 66 A at 8 kHz. It has an Ingress Protection (IP) rating of 20 and belongs to the size class D.

According to its IP rating, it is dust-resistant and protected against objects with D > 12 mm diameter. It is only suitable for industrial environments because its radio interference suppression and noise immunity meet EN 55011/EN 61800-3 standards. Furthermore, at 82° F, the perm. air humidity is less than 85%. (28^o C). The RD51.1-5B-055-D-D1-FW, like the rest of the RD500 series, must be programmed before commissioning to ensure that it performs the required functions. The ideal operating temperature is between 0 and 40 degrees Celsius. This product can be shipped globally with a one year warranty period from Wake Industrial.
