Product Description

The Bosch Rexroth RD52.2-4B-007-L-A2-FW is a three-phase drive system. The rated output of the drive is 7.5 kilowatts. The system uses a converter with brake chopper rated for 380 to 480 Volts AC input. Additional functions supported by the RD52.2-4B-007-L-A2-FW are external standby power and starting lockout. The standby power feature allows the control electronics on the RD52.2-4B-007-L-A2-FW to operate in the absence of line supply voltage. An external 24 Volts DC power supply is required for the standby power feature. Technical specifications for the RD52.2-4B-007-L-A2-FW at 4 kilohertz pulse rate include 7.5 kilowatts motor output, 18 Amps rated current, 23 Amps peak current for 60 seconds, 12 kVA rated output and 15 kVA rated output for 15 seconds. Technical specifications for the RD52.2-4B-007-L-A2-FW at 8 kilohertz pulse rate include 5.5 kilowatts motor output, 13 Amps rated current, 17 Amps peak current for 60 seconds, 8.6 kVA rated output and 11 kVA rated output for 15 seconds.

The heat dissipation during operation is 0.33 kilowatts / 0.32 kilowatts at 4 / 8 kilohertz pulse rate respectively. The RD52.2-4B-007-L-A2-FW is cooled by forced air flowing across the heating drive components. A minimum airflow of 0.03 cubic meters per second is required for proper system cooling. The drive weighs 6.5 kilograms. The IP20 rated drive system housing is built for indoor use. The environmental class of the drive is 3K3 as per DIN IEC 721-3-3. The required ambient temperature for operation is 0 to 40 degrees Celsius. Output of the drive reduces at a rate of 2.5% per K for the 40 to 50 degrees Celsius range. Firmware for the RD52.2-4B-007-L-A2-FW drive has to be ordered separately. This product can be shipped globally with a one year warranty period from Wake Industrial.
