Product Description:

The HMV02.1R-W0015 is a supply unit produced by Bosch Rexroth Indramat for the HMV IndraDrive Supply Units series. Within an IndraDrive multi-axis system, it delivers DC link power to connected inverters and returns surplus energy to the mains through its regenerative design. This operating principle supports shared DC bus installations where several servo axes draw power from one central supply section. The device is design version 1 in series version 02 and uses internal air circulation from a built-in blower for thermal management. Its housing measures 352 mm in height, 150 mm in width, and 205 mm in depth, while the mass is 9.5 kg, so it fits standard industrial control cabinets without taking excessive space.

Electrically, the unit converts three-phase input into a stabilized DC bus that can deliver 15 kW of continuous power at up to 23 A of input current. The regulated bus sits at 750 VDC, and energy is buffered by an intermediate circuit capacitance of 0.705 mF, which smooths voltage changes created by dynamic motor loads. Continuous internal losses are limited to 500 W, which helps reduce the heat load inside the cabinet. The supply also permits horizontal spacing of 0 mm between adjacent modules, while installation still requires free space above and below the housing so the blower intake and exhaust remain unobstructed.

Dynamic events are handled by an integrated brake chopper that can dissipate up to 40 kWs of cumulative energy and reach a peak braking power of 33 kW during rapid deceleration cycles. When regeneration alone is not enough, the unit can deliver a controlled DC output current of 20 A to external discharge elements. Only 27 W of control supply power is required to operate the logic and fan assembly, which keeps the auxiliary power demand low. This arrangement supports stable energy handling during rapid speed changes and repeated braking events on connected axes.
