KVR1.3-30-3

The KVR1.3-30-3, Bosch Rexroth Indramat, KVR Power Supply Modules module serves as a high-performance power supply unit tailored for demanding industrial AC drive environments. This module rectifies three-phase mains into a stable link circuit voltage of 320 V, feeding downstream drives with consistent power. The supply delivers a rated power of 30 kW and offers auxiliary voltage outputs of 24 V for control and signaling circuits. Its regenerative design seamlessly transitions into inverter mode to return up to its full capacity back to the mains during generator-driven operation.

Built around a rugged modular architecture, the KVR1.3-30-3 integrates buffer capacitors to smooth DC ripple and support dynamic load changes. It accepts an input voltage range of 380–460 V AC at 50/60 Hz, and sustains a maximum overload capacity of 100 kW for brief peak demands. The module’s regenerative capability absorbs braking energy without external resistors, while a dedicated power backfeed function protects upstream networks. Advanced heat sink technology and forced-air cooling maintain optimum junction temperatures, ensuring stable operation across full load cycles.

Engineers benefit from the KVR1.3-30-3’s plug-and-play integration into Bosch Rexroth’s AC drive ecosystem, simplifying multi-axis installations and reducing cabinet footprint. Its proven reliability under continuous industrial use minimizes maintenance intervals and maximizes uptime. Ideal for high-speed conveyors, extruders, and process lines, this power supply module guarantees efficient energy management and robust system performance.
