Product Description:

The HVR02.2-W010N-RE02 belongs to the HVR Power Supply Units series manufactured by Bosch Rexroth Indramat. As a regulated supply module, it draws three-phase energy from plant mains and delivers a steady DC bus for multiple servo drives or inverters in an automation cabinet. It converts incoming AC power into the DC link required by downstream servo electronics, allowing several axes to operate from one centralized source. This arrangement simplifies the overall drive structure because the axis controllers can focus on motor control rather than line rectification. By handling this conversion internally, it removes the rectifier and braking circuitry from each axis controller and centralizes power regeneration management.

This unit uses internal air cooling with a built-in blower, so forced airflow moves heat from the power semiconductors to the rear exhaust path without external ducting. The airflow path helps the module remain thermally stable during continuous operation in enclosed cabinets. It accepts a three-phase input of 3 × AC 380–480 V, and the electronics remain operational within a line deviation of ±10% tolerance. The rectifier and intermediate circuit create a regulated DC bus voltage, helping connected drives maintain a stable link during acceleration, deceleration, and other load transients. Rated for a maximum of 10 kW output, the module can supply several medium-power axes at the same time instead of requiring a separate supply section for each controller. Stable bus conditions also help connected inverters respond more consistently when several axes change speed at once.

The unit is Version 2. It is part of Series 02, which keeps mounting dimensions and wiring points consistent within this product line. The module includes integrated protective relays, capacitors, and charging resistors, so only the bus bars and control cables need to be connected in the cabinet. In coordinated motion systems, it serves as a common DC source for synchronous servo axes and allows regenerated energy from one axis to remain available on the shared DC bus. This supports multi-axis operation where power demand can shift quickly from one motion cycle to the next.
