Product Description:
The HVR03.2-W045N/S200 is a power supply module from the HVR Power Supply Units series by Bosch Rexroth Indramat. Installed in central drive cabinets, the unit converts three-phase mains energy into a stabilized DC bus that feeds multiple servo inverters and regenerative braking circuits. By maintaining a constant intermediate circuit voltage, it supports coordinated motion sequences and energy exchange among connected axes in packaging lines, printing presses, and material-handling gantries. Its housing format matches Indramat drive racks for straightforward cabinet integration.
The supply stage accepts 3 x AC 380 V to 480 V and remains operational within ±10% input tolerance, allowing connection to standard factory power systems without special transformers. Cooling is provided by internal air cooling with a built-in blower, so airflow passes across heat sinks to keep internal components within their operating limits. The rectifier and chopper produce a regulated DC bus voltage for the intermediate circuit. Continuous output is 45 kW, which is suitable for multiple high-power drives and regenerative energy during deceleration. The unit is built as design version 2 for compatibility with the corresponding generation of Indramat digital drives.
The code 03 identifies the power class used with medium-frame servo amplifiers, helping match bus capacity to the number of connected axes. The module belongs to the HVR Power Supply Units series and uses the standardized mounting dimensions and shared interface connectors used in that product line. It is manufactured by Bosch Rexroth Indramat and can be integrated with HDS, DDS, or DKS drives that operate from the same DC bus. Stable intermediate-circuit support allows connected axes to exchange energy during acceleration and braking without additional converters.
