Product Description:
The RD52.1-7N-160-R-M1-FW RD 500 Drive Controller manufactured by Bosch Rexroth. This device is designed to control electric drives in industrial applications. It is built to deliver reliable performance in demanding environments. The RD 500 Drive Controllers offer a motor output of 160 kW which provides efficient power control.
The RD52.1-7N-160-R-M1-FW RD 500 Drive Controller operates with a supply voltage ranging from DC 530 to 670 V (~10%). The controller supports an output frequency from 0 to 250 Hz for flexible frequency regulation. The rated current for the drive controller is 230 A for stable and effective motor operation. It can handle a peak current of 299 A for up to 60 seconds and 391 A for 1 second. These capabilities allow the drive to manage dynamic load variations without compromising performance. With a rated output of 151 kVA, the controller confirms sufficient power capacity for demanding applications. The cooling is crucial for maintaining operational efficiency. The RD 500 Drive Controllers require a cooling air flow of 0.4 m^3/s. The cooling mode used is liquid cooling with an internal pump for optimal temperature management for long-lasting performance. The device features a power loss of 5.2 kW, which is typical for systems with such high output ratings.
The RD52.1-7N-160-R-M1-FW RD 500 Drive Controller uses line field-oriented regulation for precise control. It is designed as an inverter unit with a brake chopper, but without a built-in brake. The system also functions as a frequency converter which supports frequencies above 150 Hz. However it does not include an output choke. Overall, the drive controllers are engineered to deliver reliable and efficient performance in industrial drive control.
