Product Description:
The HMV02.1E-F0075-A-07-NNBN is a DC-bus supply unit produced by Bosch Rexroth Indramat as part of the HMV IndraDrive Supply Units series. As an HMV supply unit, it converts three-phase mains power into a stabilized high-voltage rail that feeds multiple IndraDrive inverters in coordinated automation cells. The device supports energy exchange between motor drives and routes regenerated power back to the supply, allowing compact cabinet layouts in metal-cutting, packaging, and material-handling installations where centralized power distribution is required. By supplying a common DC bus, the unit allows multiple axes to share available energy during changing load conditions.
This model delivers a rated output of 75 kW, providing sufficient headroom for several high-torque axes connected to the same DC link. It sustains the bus at DC 700 V, a level that balances motor response with the insulation demands of standard industrial wiring. Thermal loads are managed by liquid cooling, so waste heat is transferred to an external heat exchanger instead of the control cabinet air. The internal electronics are protected to IP20, which indicates finger-safe terminals while still relying on the enclosure for broader protection. During rapid deceleration, excess kinetic energy is dissipated by an integrated braking transistor, preventing overvoltage and removing the need for a separate brake chopper.
The unit is supplied in a fed configuration, meaning it draws its own auxiliary power from the connected mains rather than from an external control transformer. The unit is Design Version 1 and belongs to Series Version 02 within the HMV platform. These identifiers place it in the first mechanical and electrical iteration of this platform and match it with the corresponding product generation. This arrangement supports centralized power distribution across multi-axis production lines that use a common DC bus, and it helps keep cabinet power architecture organized when several inverters share the same supply section.
