Product Description

The Bosch RD52.1-4B-018-L-LV-FW is an advanced three-phase drive system. It is based on a converter that includes a brake chopper. The drive converter is designed for three-phase input at 380 to 480 Volts AC. The rated motor output of the RD52.1-4B-018-L-LV-FW is 18.5 kilowatts. The drive system is designed to control electric motors and to monitor their operation. The drive system should be programmed prior to commissioning. Typical applications for the RD52.1-4B-018-L-LV-FW include chemical and process technology, packing and foodstuff machines and machine tools. The drive system should only be operated under the specified mounting and ambient conditions. The specified ambient conditions include 0 to 40 degrees Celsius temperature, altitudes of up to 1000 meters, dust-free air, less than 90% non-condensing humidity, and sufficient spacing from other heat-generating device sin the vicinity.

The rated motor output of the RD52.1-4B-018-L-LV-FW is 18.5 kilowatts at 4 kilohertz switching frequency and 15 kilowatts at 8 kilohertz switching frequency. The rated current of the drive system is 35 Amps at 4 kilohertz and 30 Amps at 8 kilohertz. The peak current output for 1 second is 60 Amps at 4 kilohertz and 51 Amps at 8 kilohertz. The rated apparent power output is 23 kVA at 4 kilohertz and 20 kVA at 8 kilohertz. The cooling method is forced air cooling and the minimum airflow requirement as specified by Bosch is 0.05 cubic meters per second. If the air flow rate is lower than the specified value then the drive system could heat up and get damaged.. The ingress protection rating for the RD52.1-4B-018-L-LV-FW drive system is IP20 and cabinet mounting is recommended. Weight of the drive is 11 kilograms. This product can be shipped globally with a one year warranty period from Wake Industrial.
