Product Description:

The HVR02.2-W010N/S204 belongs to the HVR Power Supply Units series from Bosch Rexroth Indramat. It is a regulated power module that feeds the shared DC bus in an Indramat drive cabinet, allowing multiple servo inverters to draw energy from a common source. Within an automation cell, this type of supply stabilizes the intermediate circuit so axis controllers receive consistent voltage during acceleration, regeneration, and standby states. Because the energy source is centralized, several connected drives can operate from one regulated supply section instead of separate standalone power inputs. This layout suits cabinets where coordinated axes share one common DC link.

The unit draws power through a three-phase mains interface rated for 3 x AC 380 V to 480 V. Internally, heat is removed by internal air cooling with a built-in blower, which forces cabinet air across power semiconductors and bus capacitors. The output stage maintains a regulated DC bus voltage, helping prevent load-dependent drift that could disturb downstream drives. With a continuous capability of 10 kW, the supply can support several medium-frame motors without exceeding its thermal limits, and the unit is Design Version 2 in this product line. Forced airflow also helps move heat away from the internal power section during sustained operation.

The control board supervises mains balance and trips if phase deviation exceeds the ±10% tolerance allowed for input variation. The module integrates directly with Indramat bus bars and standard interface cables used in the series. All electronic and mounting dimensions follow Series 02 conventions, which keep the module aligned with the rack format used by related components. This monitoring function helps protect the DC supply stage when the incoming three-phase line becomes uneven.
