Product Description:

The HVR02.2-W025N/S202 is a regulated power supply built by Bosch Rexroth Indramat for DC-link operation in multi-axis drive systems. It belongs to the HVR Power Supply Units series, which provides centralized bus voltage to connected servo and spindle drives. By converting three-phase mains energy to a steady internal DC level, the unit supplies the intermediate circuit that feeds all inverters within an automation cell. This arrangement allows several axes to share one supply section instead of using separate rectifier stages for each drive.

Within this single cabinet frame, the hardware follows Design Version 2, indicating the second mechanical and control revision. The input stage accepts 3 x AC 380 V to 480 V (±10%), so the supply tolerates common plant voltages without separate transformers. Cooling relies on internal air cooling with a built-in blower. The integral fan moves air through heat-sink channels, eliminating external ducts. After rectification and smoothing, the converter outputs a regulated DC bus voltage that stays stable under load changes, which supports steady torque production from the attached drives. Continuous apparent output capability reaches 25 kW, allowing several medium-power axes to share one power module during simultaneous acceleration events. A regulated bus also helps the connected inverters maintain consistent response when demand changes quickly across the system.

The code 02 places the unit in the later version of this product line, and the housing is intended for single-cabinet installation where centralized DC-link distribution is used. As an HVR power supply unit, it works with digital controllers and regenerative brake options in the same drive system. Keeping the supply section separate from the inverter sections helps organize protective devices and diagnostic connections within multi-axis cabinets. It can serve as the common energy source for coordinated motion systems that group several servo or spindle axes on one shared power platform.
