Product Description:
The HMV02.1E-F0025-A-07-NNBN supply unit is produced by Bosch Rexroth Indramat and belongs to the HMV IndraDrive Supply Units series. It functions as the central power module in an IndraDrive system by rectifying incoming AC and maintaining a shared DC link for multiple inverters. This arrangement reduces component count, eases cabinet layout, and supplies stabilized energy for synchronous or induction motors used in presses, handling robots, and fast-cycle packaging equipment. By centralizing rectification in one module, the system can distribute bus power across several axis drives from a common source.
The unit uses liquid cooling, so heat is removed through a closed coolant circuit rather than through forced air, which permits higher current density in confined enclosures. Because heat is transferred to the coolant loop, less thermal load is released into the cabinet air space. Its DC link operates at a nominal DC 700 V, giving inverters a wide voltage margin for rapid torque development and controlled regeneration. The unit is design version 1, so the hardware layout and terminal pattern match the first mechanical revision of the supply platform. A continuous output capability of 25 kW supports medium-power multi-axis machines, and the IP20 housing provides basic finger protection when mounted inside a sealed cabinet.
An internal circuit includes an integrated braking transistor; this semiconductor diverts surplus DC energy into an external resistor whenever regenerative current exceeds bus capacity, which helps prevent overvoltage trips. The external resistor is mounted separately, while the switching function remains inside the supply unit. The supply uses a line-fed configuration, so incoming mains conductors are routed only into this module, and all connected drives draw DC through the bus bars rather than from separate rectifiers. The unit is Series Version 02, matching other second-generation IndraDrive units in the same platform. The cabinet can also include coolant manifolds, an external brake resistor, and DC distribution rails for connected axes.
