performance: 0,25 - 22 kW
The frequency inverter SK 200E for decentralised system versatility – up to 22.0kW After many years of experience with motor-mounted frequency inverters, with the release of the SK 200E NORD has introduced a series of devices which enable a wide range of decentralised drive technology solutions. These robust, reliable and economic systems are suitable for extensive plant, e.g. conveyors, and were specially optimised for price-sensitive market segments. Similar to the SK 500E Panel Mount family, an application-oriented performance level is available which offers the same high quality functionality. Expected features of decentralised components such as robust design, integration of plug connectors, rapid replacement and decentralised modules for communication and I/O signals ensure reliable integration of distributed drive units at the field level.Scope of supply – Frequency inverter SK 200E:
  • 1~ 115 V 0.25 – 0.75 kW
    1~ 230 V 0.25 – 1.1 kW
