The new SK 180E is directly mounted on asynchronous motors as its larger counterparts. Featuring proven ISD vector control, the SK 180E is even more cost-effective than the currently available range of decentralised units.
Focussing on the core requirements of speed, control and efficiency, the new NORD frequency inverters feature two analogue inputs and integrated process and PI controller functions to autonomously manage simple drive applications. The new units are suitable both for standalone variable frequency drives and synchronised operation with several units.
The SK 180E also contains all necessary functions for many fan and pump applications, saving up to 30% energy by automatic magnetisation 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.
The variable frequency drives are available complete with a conventional mains plug for use in mobile pumps, shredders, or mixers. The drives have typical overload reserves of 150% for 60 seconds and briefly even up to 200%. All distributed drive electronics from NORD follow the same simple and versatile operation concept: they can be programmed directly by means of parameter boxes, or via 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 control diagonal and vertical conveying tasks with safety requirements up to SIL3, NORD’s decentralised solutions also include the very economical SK 135E soft and reverse starter, which can carry out simple switching tasks in logistics and conveying.
