Product Description:
The HVE03.2-W030 is a regulated DC link supply designed by Bosch Rexroth Indramat for the HVE Power Supply Units series. As an HVE power supply unit, it feeds multiple drive controllers from a common three-phase mains connection, delivering stabilized DC and control voltages required in modular motion platforms used in industrial automation. This shared-supply arrangement supports multi-axis systems that use one central power section for several connected drives. The HVE03.2-W030 designation indicates design version 2 and places the module in the mid-range of the series for compact machine tool cabinets.
At full load, the unit can deliver a continuous output of 30 kW and draws about 46 A from a 400 V mains supply when the recommended 16 mm² conductors are used. Upstream protection is provided with a maximum fuse size of 63 A, which matches the converter’s inrush and steady-state demands. During rapid motor deceleration, excess DC-bus energy is dissipated by an integrated bleeder path that accepts transient peaks up to 100 kW without external resistors. For auxiliary electronics, the supply provides a separate 300 W control voltage rail so drives, I/O, and safety relays can be powered from the same chassis. This arrangement reduces the need for additional low-power supply modules inside the cabinet.
Thermal performance is managed by an internal blower, and under steady conditions the bleeder resistor continuously converts up to 1.5 kW of kinetic energy to heat while overall conversion losses reach 355 W at maximum electrical output. The DC link can absorb 100 kWs of regenerated energy, so short braking events can be handled without overshoot. The housing is 150 mm wide and weighs 16 kg, and its IP10 open-frame design permits airflow when relative humidity remains below 95%. Because the enclosure is open-frame, the unit is intended for installation in a protected cabinet where air can move freely around the module.
