KDV1.2-100-220/300-220

KDV1.2-100-220/300-220, Bosch Rexroth Indramat, KDV Supply Modules deliver robust AC-to-DC conversion for servo drive systems, offering a seamless interface between the mains and up to 24 kW of connected drives. The module's triple-phase rectifier transforms 220 VAC into a regulated DC bus; a high-capacitance buffer smooths out voltage ripple and maintains stable operation even under regenerative loads. Integrated LED indicators monitor power ON/OFF status, earth connection, and auxiliary voltage levels, while embedded warning sensors detect bleeder overload conditions in real time. This ensures the supply remains within safe operating parameters and prevents unplanned downtime.

Designed for demanding industrial environments, the KDV1.2-100-220/300-220 features a Current Rating of 100 A and a DC Bus Nominal Voltage of DC 300 V. Both the Nominal Voltage for Power Electronics and the Nominal Voltage for Heatsink Blower are set to AC 220 V, simplifying field wiring and reducing component variety. The presence of a heatsink (Heatsink: Yes) and active Monitoring Functions: Yes enables continuous thermal management and fault reporting via the signal-voltage bus. Classified under the Applications: Industrial category, this version (Version: 2) of the product group (Product Group: KDV, Series Code: 1) is tailored for machine builders who require precise, high-current DC bus supplies.

Integration into existing drive architectures is straightforward: each servo drive connects to the PE busbar via its own ground conductor, and the dynamic brake function protects against overvoltage by dissipating regenerated energy through the bleeder resistor. When upstream power fails, the DC bus maintains supply to signal voltages, guaranteeing safe shutdown and data retention. Engineers will appreciate the module's compliance with machine-circuit diagrams, clear interface definitions, and the enhanced reliability afforded by constant monitoring and thermal protection.
