Product Description:

The KMV03.1R-B0007-P-D7-ET-NNNN-FW supply module is produced by Bosch Rexroth Indramat within the KMV Regenerative Power Supplies series. Designed for cabinet or machine integration, it returns excess DC bus energy to the mains instead of wasting it as heat. By stabilizing bus voltage and recycling power, the unit supports efficient operation of multi-axis IndraDrive systems.

The module regulates the DC link at 750 VDC, matching the voltage window required by servo inverters. Its conversion stage is rated for 7.5 kW, defining the continuous regenerated power it can process without derating. A line draw of 12.0 A under nominal conditions guides mains conductor sizing. Internal circuitry dissipates up to 500 W of switching loss, which should be considered in the thermal design.

Communication for diagnostics and commissioning is handled through the Multi Ethernet interface, simplifying network architecture inside modern automation cells. During dynamic braking events, the supply can feed back 10.0 A into the grid, absorbing motor-generated overvoltage and protecting connected drives. Environmental sealing meets IP65, so the housing resists dust ingress and low-pressure water jets. Efficient heat removal is achieved by a cold-plate thermal interface, and the unit withstands fault currents up to 42000 A rms on high-capacity mains feeders.

Wake Industrial can arrange same-day shipping for urgent maintenance needs. Every purchase includes a 1-year warranty, and quotations remain valid for 30 days to simplify budget approval cycles.
