Product Description:

The HMV01.1E-W0120-A-07-NNNN-AA supply module is produced by Bosch Rexroth Indramat for the HMV IndraDrive Supply Units series. Installed in centralized control cabinets, the unit rectifies incoming three-phase AC power and maintains a regulated DC link for coordinated servo and spindle drives. This allows several connected converters to draw from one common power source instead of using separate supply sections for each axis. By pairing one supply with several converters, the system can reduce wiring complexity and share regenerated energy across axes in packaging, printing, or handling equipment.

The module has a continuous power rating of 120 kW, so the shared bus can support high demand during simultaneous axis acceleration. The link potential is fixed at DC 700 V, which matches IndraDrive inverter sections and supports stable power conversion across the connected drive group. Thermal management uses internal air cooling with an integrated blower, and the fan moves cabinet air through internal channels to remove heat from the power semiconductors without external ducting. The enclosure has an IP20 rating for finger-safe protection when mounted in a closed rack. The incoming mains uses a line-fed configuration, so line power is supplied to the module rather than regenerated energy being returned to the grid.

This hardware is Design Version 1 and Series Version 01. The device is designated as an HMV supply unit, which identifies it for use with HMS or HCS converters on a common DC bus. In a multi-axis cabinet, the supply section provides the DC source while the connected converters handle current and voltage control for the individual motors. This arrangement suits systems that need centralized power distribution for several coordinated axes without requiring a separate supply module for every converter.
