Mounted on asynchronous motors, the SK 180E distributed frequency inverters feature proven ISD vector control, and are even more cost-effective than the currently available range of decentralised units.
The new inverter focuses on the core requirements of speed control and efficiency. Featuring two analogue inputs and integrated process and PI controller functions, the SK 180E can autonomously manage simple drive applications.
Suitable for standalone variable frequency drives as well as synchronised operation with several units, the SK 180E distributed frequency inverters contain all necessary functions for fan and pump applications, saving up to 30% energy by automatic magnetization adjustment under partial load.
Providing class C1 radio interference suppression and a discharge current below 16 mA, the SK 180E can even be operated in residential and business buildings in nearly every country in the world. Designed for use in mobile pumps, shredders, or mixers, variable frequency drives are available complete with a conventional mains plug.
The drives have typical overload reserves of 150% for 60 seconds and briefly even up to 200%. All distributed drive electronics from NORD including the SK 180E can be programmed directly by means of parameter boxes or a computer using the free-of-charge NORD CON software.
Parameters can be quickly exported to other devices using the internal system bus or Ethernet interfaces. In addition to the SK 180E and the SK 200E, which can also control diagonal and vertical conveying tasks with safety requirements up to SIL3, NORD’s decentralised solutions also include the very economical new SK 135E soft and reverse starter to carry out simple switching tasks in logistics and conveying.
