HMV IndraDrive Supply Units
The Bosch Rexroth Indramat HMV01.1E-W0120-A-07-NNNN from the HMV IndraDrive Supply Units series is a high-performance HMV Supply Unit engineered for demanding industrial drive applications. Delivering a rated output power of 120 kW at a DC bus nominal voltage of DC 700 V, this feeded module provides robust, stable power to synchronous and induction drives. Its power supply configuration is designed for direct integration into centralized drive systems, and the absence of auxiliary modules is confirmed by the specification “Other Design Feature: None.” Built as Design Version 1 and marked as Series Version 01, the unit reflects Bosch Rexroth Indramat’s commitment to consistent revision control and backwards compatibility.
Cooling and protection are handled with precision: an internal air with integrated blower ensures uniform temperature distribution across power semiconductors, while the IP20 protection rating safeguards against solid contaminants in control cabinets. The integrated blower is optimized for low acoustic noise and minimal maintenance intervals, and the unit’s compact footprint supports high-density rack installations. All critical interfaces and power terminals are arranged for straightforward access during commissioning and service.
Together, these specifications make the HMV01.1E-W0120-A-07-NNNN an ideal power backbone for multi-axis motion controllers, CNC systems, and material-handling machinery. Its feeded topology simplifies DC bus architecture by eliminating intermediate rectifiers, thereby reducing total system losses. Whether deployed as a standalone supply or in parallel redundancy configurations, this unit guarantees reliable energy delivery under continuous and peak load conditions.

Frequently Asked Questions
How does the short-circuit current rating (42,000 A RMS) affect protection and cabling choices?
The extremely high SCCR means upstream circuit breakers and fuses must be rated and selected to safely interrupt faults without causing damage. Cable insulation, selection and cross-section must match to avoid thermal runaway in a fault event.
In what way does the “feeded power supply” (non-regenerative) configuration influence energy returns compared to a regenerative type?
A feeded (non-regenerative) configuration cannot feed energy back into the mains during deceleration or braking; so regenerative braking energy is dissipated internally (often via resistors). This leads to higher energy losses in dynamic applications vs regenerative types.
What is the impact of the dual capacitance to housing (2 × 470 nF) filters on electromagnetic compatibility (EMC)?
These capacitors act as EMI suppression filters by shunting high frequency switching noise to the chassis, reducing conducted and radiated emissions. Proper grounding of the housing is essential to allow them to function correctly and avoid safety hazards.
What are the implications of the device’s Weight (22 kg) and dimensions (250 × 440 × 262 mm) for mechanical mounting and enclosure design?
The enclosure must include proper mounting brackets or joint bars capable of supporting 22 kg plus dynamic loads; vibration isolation may be needed in mobile or high-shock environments. Also, the size requires planning for cooling airflow and free space per side/top per Bosch guidelines.
How is input current (128 A) related to sizing of the upstream AC supply and overcurrent protection?
The AC mains and upstream breaker/fuse must be rated not merely for steady input current but also for inrush current and potential peaks during startup; wire gauge and thermal rating must handle sustained current without overheating. Also, the tolerance on mains voltage and frequency influences how close to maximal input current the unit operates.
