Product Description:

The HVR03.2-W045N/S204 belongs to the HVR Power Supply Units series produced by Bosch Rexroth Indramat. This unit is a regulated DC bus power supply that converts three-phase line power into a stable intermediate circuit for Indramat drive packages and motion controllers used in automated machinery. By delivering high-capacity DC power, it serves as the electrical backbone for multiple servo or inverter axes connected to a common source. This arrangement helps reduce cabinet wiring and supports coordinated multi-axis systems in production equipment.

The unit accepts a mains feed of 3 x AC 380 V to 480 V (±10%), so it can be placed on standard industrial distribution systems without an isolation transformer. Cooling is handled by internal air cooling assisted by a built-in blower, which keeps semiconductor devices and bus capacitors within their thermal limits during continuous operation. The supply produces a regulated DC bus voltage, reducing output sag that could disturb connected drives during load surges or rapid axis acceleration. With a power capability of 45 kW, the device can furnish substantial current to several axes running at the same time in gantries, packaging lines, and printing presses.

The unit is design version 2. It uses the same interface conventions found across the Bosch Rexroth Indramat automation platform, which supports orderly wiring and consistent connections to matching drives. As part of the HVR Power Supply Unit line, the model follows the cabinet dimensions and mounting points used for this family. The front layout remains consistent with related modules, which helps keep cabinet organization clear in multi-axis assemblies. The unit is in Series 03, and its connection pinout and protective circuitry match other 03-series HVR supplies used in related systems.
