Product Description:

The HMV01.1E-W0120-A-07-NCNN supply module is manufactured by Bosch Rexroth Indramat and belongs to the HMV IndraDrive Supply Units series. As a regulated DC-bus source, it feeds energy to multiple IndraDrive inverters so that coordinated servo axes receive stable intermediate-circuit power. Within an automation cell, the unit links the three-phase mains to the shared DC link, acting as the central power interface for motion controllers and synchronous motors. Because one supply module can support several attached inverter sections, it centralizes power conversion in systems that use a common DC bus.

At the output side, the supply module can deliver 120 kW of continuous power, enabling large multi-axis machines to run from a single source rather than from separate supply sections. Its intermediate circuit is maintained at DC 700 V to match the voltage range used by IndraDrive converters while helping reduce current and conductor size. Heat generated by switching devices is removed through internal air cooling with an integrated blower, so cabinet airflow does not depend on external fans. The enclosure has an IP20 protection rating, which means live parts are guarded against finger contact and the unit must be installed in a closed panel. The module uses a mains-fed power supply configuration, so it draws energy from the AC mains and does not regenerate power back to it.

The unit is identified as Design Version 1, indicating the first design revision for this HMV platform. It is also assigned Series Version 01, which is the series code used for this model variant. Classified as an HMV Supply Unit, the device contains rectifier and chopper circuitry, while axis control, motor feedback, and fieldbus communication are handled by the connected inverters. This arrangement keeps the module focused on DC-bus generation and energy management while the attached inverter sections manage motor-specific control functions.
