Indramat HVE

Indramat HVE

The power supply units HVE and HVR rectify 3-phase AC voltage. While HVR units offer regulated DC bus voltage, HVE units provide unregulated DC bus voltage for drive controllers. In generator mode, HVE units dissipate regenerated energy as heat through a bleeder resistor, whereas HVR units feed regenerated energy back into the mains.

HVE and HVR power supply units serve as crucial components within Rexroth Indramat drive and control systems, specifically HDD and HDS types, by facilitating power and control voltage supply. These units are compatible with mains voltages ranging from 3 x AC 380 to 480 V, making them versatile across various power systems without necessitating transformers. The HVR units support motors with a maximum continuous mechanical power of 36 kW, while the HVE units can accommodate motors up to 60 kW. Their high DC bus voltage enables compact unit dimensions without compromising performance. Additionally, each power supply unit integrates a contactor for swiftly shutting down power supply when necessary, ensuring operational safety and efficiency.
