Inverters, what for?

  • Main purpose:
    • Compressor rotation speed (capacity) control
    • Required for all compressors with BLDC motor (higher speed range and better efficiency)
  • Additional benefits:
    • Overall less energy consumption:
      • Less startups
      • Better energy efficiency of DC motors (Inverter alone efficiency around 95-96%)
    • Soft starts
      • Lower current required for starting (max 2 times nominal, direct starting 5-7 times)
      • Less ware of compressor parts during startup
    • Possibility to control the pressures/temperatures directly by inverter
    • Adaptability to the process

Optional interface for communication to PC

• ASK-USB: Communication to PC via optional communication cable;


• Power choke type LCVS & LCVT: Power choke types LCVS (for single-phase power installation) and LCVT (for three-phase power installation) increase the overvoltage protection of the inverter and increase the system's EMC; • Power filters type FTV: Depending on the application boundaries, certain EMC levels must be achieved. The power filters are a component to improve EMC behavior in a machine installation.
