Product description

What to know about KDV3.1-100-220/300-220

The KDV3.1-100-220/300-220 is an Indramat KDV power supply module used to provide DC-bus and control power in legacy modular drive systems. KDV supplies support compatible servo and spindle drive modules mounted in the same system.

The type code identifies a KDV series 3, design 1 unit with a 100 A family rating and 220 V AC / 300 V DC system designation. The final 220 suffix is part of the configuration and should be retained when searching or requesting a replacement.

Because KDV systems can differ in transformer, bleeder and fan arrangements, Litco checks the complete nameplate and cabinet application before confirming compatibility. Current condition and price are provided by quote.

Compatibility checklist

Before replacing KDV3.1-100-220/300-220, match the complete nameplate and machine configuration.

  • Complete supply code: Verify the family, design, power rating, voltage class, cooling field, material number and all suffixes on the nameplate.
  • Cabinet configuration: Identify incoming mains, transformer and line components, connected drive modules, total axis load and DC-bus arrangement.
  • Braking and cooling: Record bleeder, regeneration, braking resistor, fan or cooling hardware and the machine duty that loads the supply.
  • Fault evidence: Include fault indicators, fuse or breaker history, operating state and clear connection photos before the module is removed.
