Product Description:
The HVE03.1-W030N power supply unit is produced by Bosch Rexroth Indramat for the HVE Power Supply Units series and is used in 600 V DC bus systems. The device converts three-phase mains energy into regulated intermediate circuit power for compatible drive controllers, and it also provides a separate 24 V control voltage output for auxiliary electronics. By combining supply conversion, energy recovery, and braking functions, it supports compact cabinet layouts in industrial automation cells. This arrangement allows the module to feed a shared DC bus while also supporting control circuits that must remain active during normal machine operation.
During continuous operation, the unit can dissipate 1.5 kW of bleeder power to keep the DC bus within safe limits, while its total rated throughput is 30 kW. At a 400 V line supply, it draws up to 46 A, so upstream protection uses a 63 A fuse. Cooling is provided by an internal air system with a built-in blower, so no external fan is required. Basic losses are 175 W at idle and rise to 355 W at maximum output, which corresponds to 6 W per kW delivered. Load demand up to 850 VA for ancillary circuits is supported, and the built-in 500 W control supply keeps connected drives energized even when the main DC link is discharged. No additional design feature is indicated in the part code, so the unit is the standard configuration.
For transient events, the bleeder resistor can absorb a 100 kW peak for short intervals, and the storage capacitors can take back 100 kWs of regenerated energy without external chokes. This allows regenerated braking energy from decelerating axes to be handled inside the supply module during short-term events. Operation is permitted at ambient temperatures up to 55 °C with derating, and installation heights can reach 1000 m before cooling margins must be reduced. The housing weighs 16 kg, and its dimensions match earlier HVE frames. Power loss data and the Series 03 revision are useful for cabinet thermal planning.
