Product Description:

The HVR02.2-W025N/S200 is a modular power supply in the HVR Power Supply Units series developed by Bosch Rexroth Indramat. It converts three-phase line power into a shared DC link for servo and spindle drives that operate on the same intermediate circuit. In an automation cabinet, it serves as the central energy source for the drive group and provides the constant supply needed for coordinated axis motion. This layout supports rapid acceleration and deceleration across multiple axes while keeping the power conversion function separate from the individual inverters.

In Design version 2, the unit connects directly to 3 x AC 380–480 V industrial power systems. Its converter stage is rated for 25 kW of continuous output, so connected axes can draw substantial electrical power without destabilizing the shared bus under normal operating conditions. The output is a regulated DC bus voltage, which gives downstream inverters a consistent supply even when the incoming line level changes within the permitted range. Thermal management uses internal air cooling with a built-in blower, allowing the unit to remove heat without external cooling hardware. The product is part of Series 02, which places it within the second design line of this power supply platform.

An input tolerance of ±10% allows the unit to operate properly where plant voltage varies because of long feeder runs or lightly regulated transformers. The device is an HVR Power Supply Unit, so its role is to feed the common DC bus rather than control a motor directly. It can absorb regenerated braking energy from connected axes and return that energy to the supply, which helps reduce heat inside multi-axis cabinets during deceleration. This operating method is useful in systems with frequent speed changes, repeated stopping cycles, or shared-bus drive groups that place varying demands on the power section.
