Product Description:

The HMV01.1R-W0120-A-07-NNNN-AA is a power supply module produced by Bosch Rexroth Indramat for the HMV IndraDrive Supply Units series. Serving as the interface to three-phase line power in an automation cabinet, the unit converts incoming AC power into a stabilized DC link that can be shared by multiple IndraDrive axes. This arrangement lets several connected drives operate from one common supply section instead of using separate line-side units. Centralized energy handling also helps reduce cabinet wiring and supports coordinated start-up and shutdown of connected motion equipment. The module is intended for installation inside a ventilated electrical enclosure where controlled airflow and compact layout are important.

The supply provides a nominal DC bus voltage of DC 700 V, which gives connected inverters a stable energy rail for current control. Its continuous output capability reaches 120 kW, allowing multiple axes to draw power from the common link during normal operation. The power stage is regenerative, so braking energy is fed back to the mains instead of being dissipated in external resistors. This operating method can reduce excess heat during deceleration events in multi-axis systems. The enclosure has an IP20 rating for finger-safe protection, and heat is removed by internal air cooling with an integrated blower. The integrated blower moves air across internal heat-producing components without the need for external ducting.

The unit is identified as design version 1 and series version 01, placing it within the early release structure of this product line. It is classified as an HMV Supply Unit, so it provides the shared DC bus function without integrated drive control or motor feedback interfaces. Motor control and encoder processing remain in the connected axis modules rather than in the supply itself. This layout is suited to cabinets where one central supply source feeds several compatible IndraDrive components. It also keeps the module focused on line conversion, energy return to the mains, and thermal management inside the enclosure.
