Product Description

The Bosch RD52.1-4B-022-L-V1-FW/S137 is a RD 500 RD52 series drive controller. The 22 kilowatt controller is based on a converter rated for three-phase AC input at 380 to 480 Volts. The converter includes a built-in brake chopper. As Bosch provides different firmware versions that support different feature sets, the firmware for the drive controller has to ordered as a separate subposition. The RD52.1-4B-022-L-V1-FW/S137 controller operates at 4 and 8 kilohertz pulse frequencies. The system specifications vary with the configured pulse frequency. At 4 kilohertz, the range of output frequency is 0 to 250 Hertz, the current rating is 43 Amps, the peak current rating for 60 seconds is 55 Amps and output power rating is 28 kVA. At 8 kilohertz, the range of output frequency is 0 to 500 Hertz, the current rating is 35 Amps, the peak current rating for 60 seconds is 46 Amps and output power rating is 23 kVA.

Environmental class of the RD52.1-4B-022-L-V1-FW/S137 is 3K3 as per DIN IEC 721-3-3. The working temperature range is 0 to 40 degrees Celsius. The power reduces by 2.5% per K between 40 and 50 degrees Celsius. the RD52.1-4B-022-L-V1-FW/S137 requires 0.1 cubic meters per second of airflow for maintaining the ambient temperature within recommended limits. Support for 24 Volt standby power is available on the RD52.1-4B-022-L-V1-FW/S137 controller. This feature allowed the control electronics on the controller to operate in the absence of mains AC input.
