Product Description:

The KMV03.1R-W06K0-P-D7-ET-NNNN-FW is a regenerative supply module from Bosch Rexroth Indramat in the KMV Regenerative Power Supplies series. It sits between the three-phase mains and a drive system’s DC link, capturing braking energy and sending it back to the grid instead of dumping it into resistors. This action lowers cabinet temperature, reduces fan demand, and saves energy during rapid starts, stops, and reversals. A stable bus delivered to companion inverters keeps torque consistent across synchronized axes in assembly, packaging, and material-handling cells.

It supports a nominal DC bus level of 750 VDC, giving connected inverters a high energy reservoir for acceleration while still allowing regeneration when the link rises above the mains potential. The power section is rated for 6 kW of continuous return capability and supplies up to 8.0 A of link current. Installation in harsh plant areas is possible because the housing carries an IP65 protection level that blocks dust and low-pressure water jets. Thermal loading is managed by forced cooling with an exterior heat sink and a mounted fan, so internal components stay within limits even when the cabinet air is stagnant. Circuit protection upstream must use a 15 A branch fuse that matches the module’s input characteristics.

The control electronics draw only 18 W, leaving most input capacity for energy recovery, and the internal semiconductor network releases a maximum of 430 W as heat under full load. A short-circuit withstand rating of 42000 A rms aligns the device with industrial feeder classes that rely on high-interrupt capability breakers. Field wiring requires conductors no smaller than 14 AWG min, a size that accommodates the specified current without excessive voltage drop. Multi Ethernet connectivity lets the module report status and fault data to PLC or SCADA layers, and firmware designated as design version 1 within series designation 03 standardizes parameter structure for identical units across a machine line.
