Product Description

The RD52.1-5B-110-L-V1-FW is a drive control device in the RD500 series manufactured by Bosch Rexroth for field-oriented vector control. It features a converter unit type, and its nominal connecting voltage is 3 x 500 V AC. Some of the industrial applications of the unit are found in conveyor technology, assembly systems, and machine tools. The RD52.1-5B-110-L-V1-FW has a variety of applications when integrated with compatible drive systems. This unit is equipped with a built-in brake chopper of 55 kW continuous power and a 2.5 Ohms minimum resistance. The maximum rated power output of the RD52.1-5B-110-L-V1-FW is 110 kW, but it tends to vary, depending on the pulse (PWM) frequency at which the device is operated. For instance, at 4 Hz, the rated power is 110 kW, while at 6 Hz, the rated power is 90 kW.

Cooling of the RD52.1-5B-110-L-V1-FW is achieved by forced convection, and it has an additional function of a 24V standby power supply. Its rated current is 195 A at 4 Hz, 165 A at 6 Hz, and 80 A at 12Hz. It belongs to size class E, and its Ingress Protection (IP) rating is IP 20. As per its IP rating, it is dust-resistant and protected against objects with D > 12 mm in size. It is suitable for industrial areas only as its radio interference suppression and noise immunity corresponds with Class A1, based on EN 55011/EN 61800-3 specifications.

In addition, its perm. air humidity is less than 85 % at 82° F (28^o C). As with all RD500 series, the RD52.1-5B-110-L-V1-FW must be programmed before commissioning to ensure that it performs the required functions. The suitable ambient operating temperature is between 0^o C and 40^o C. This product can be shipped globally with a one year warranty period from Wake Industrial.
