Product Description:
The HVR03.2-W045N belongs to the HVR Power Supply Units series manufactured by Bosch Rexroth Indramat. It is a modular power supply designed to receive three-phase mains energy and feed a common DC link that drives multiple servo or spindle inverters within an automation cabinet. By centralizing the DC source, the unit reduces wiring complexity and supports coordinated motion axes within production machinery. It fits directly into Indramat drive racks where its control logic monitors line conditions and coordinates with regenerative modules to keep bus voltage within limits.
The power module accepts 3 × AC 380-480 V (±10%) so it can be connected to standard European or North-American industrial grids without an external transformer. Inside, rectification and filtering create a regulated DC bus voltage whose stability minimizes current ripple in the downstream drives. Continuous output capability is 45 kW, supplying enough energy for several high-power axes operating simultaneously. Heat generated by the semiconductors is removed through an internal air with built-in blower arrangement; the impeller moves cabinet air across the heat sink, eliminating the need for external ducting. Together, these features maintain rated performance during sustained duty.
This unit carries design version 2, indicating the second mechanical and firmware revision for the platform and ensuring interchangeability with earlier HVR03 devices that share the 03 series code. As an element of the HVR Power Supply Units family, it aligns mechanically with standard mounting rails supplied by the manufacturer. The designation Bosch Rexroth Indramat on the nameplate guarantees component traceability and access to worldwide support channels. Classified as an HVR Power Supply Unit, it can be combined with regenerative modules to return excess energy to the grid, extending the life of braking resistors. The design profile streamlines cabinet layout while retaining clear access for service.
