Product Description

The RD52.1-4B-037-D-NN-FW is a field-oriented vector control device from Bosch Rexroth's RD500 series. It has a converter unit type and 3 x 380 – 480 V AC 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 RD52.1-4B-037-D-NN-FW has a wide range of applications. This unit has a built-in brake chopper with a continuous power of 23 kW and minimum resistance of 7 Ohms at a PWM frequency of 4 kHz. The RD52.1-4B-037-D-NN-FW's maximum rated power output is 37 kW, but it varies depending on the pulse (PWM) frequency at which the device is used. For example, rated power at 4 kHz is 37 kW, while rated power at 8 kHz is 30 kW.

A plug-through heat extraction mechanism is used to keep the RD52.1-4B-037-D-NN-FW cool, and it is not equipped with a standby power supply or additional functions. Its rated current at 4 Hz is 68 A and 56 A at 8 Hz. It has an Ingress Protection (IP) rating of 20 and belongs to the size class C. 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 RD52.1-4B-037-D-NN-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.
