Product Description:

The HVR02.2-W025N/S204 power module is built by Bosch Rexroth Indramat and belongs to the HVR Power Supply Units series. It functions as a DC bus supply that furnishes regulated energy to multi-axis drive systems, linking the mains to servo inverters used in industrial automation cells. By converting three-phase mains power into a stable DC level, the unit supplies a common intermediate circuit so connected drives can share regenerative energy and maintain coordinated motion under variable load profiles. This arrangement lets decelerating axes return energy to the shared link instead of isolating each inverter on its own supply path.

The unit handles a mains input of 3 x AC 380 V to 480 V (±10%), allowing deployment on standard factory networks without tap changing. Cooling is provided by internal air cooling with a built-in blower, so air can move through the dedicated channel without requiring a separate external fan assembly. Its continuous output capacity reaches 25 kW, so the supply can feed several axis modules whose combined demand stays within that level at nominal conditions. The airflow path helps remove heat from internal components during sustained operation. The unit is built in design version 2, which reflects the second-generation HVR layout while keeping the mounting dimensions consistent.

The module delivers a regulated DC bus voltage that stays within tolerance when the upstream grid fluctuates, helping connected drives receive a stable intermediate potential for precise torque control. Stable bus conditions also support consistent inverter response during load changes and speed transitions. It is part of series 02, placing it within a later production stage of this supply family. Braking resistors and filter assemblies are selected separately from the base unit, so the power supply can be matched to the requirements of the drive system without changing the core module.
