Product Description:

The HVR02.2-W025N/S203 is a power supply unit built by Bosch Rexroth Indramat and assigned to the HVR Power Supply Units series. In a multi-axis drive system, the module converts incoming mains power into a stable DC source that can be shared by several connected servo drives at the same time. This centralized arrangement supports coordinated motion while reducing the amount of separate power conversion hardware needed in the cabinet. It can serve as the central power conversion stage for drive groups used in packaging lines, assembly stations, and other automated machines that require synchronized axis operation.

The supply stage accepts 3 x AC 380 V to 480 V (±10%), so it can connect directly to common industrial power networks. Internally, it produces a regulated DC bus voltage, which helps connected drives operate consistently when the incoming line remains within the stated tolerance range. The unit has a peak conversion capacity of 25 kW, making it suitable for supplying several medium-power axes from one source. Thermal management uses internal air cooling with a built-in blower, so air is moved across the heat sinks without external ducting. Because the DC supply is centralized, individual drive modules can focus on motor control rather than local rectification, which helps keep the overall system layout more uniform.

The unit is identified as Design Version 2. It also carries release code 02, which indicates the matching generation used for related hardware in the same platform. Power is shared with connected drives through front-panel bus bars, allowing multiple axes to draw from the same DC source. The front connection arrangement also keeps the shared power path accessible within modular rack layouts. Regenerative braking energy can be handled at the supply level, which supports grouped drive installations that return energy to the common bus during deceleration.
