New no frills frequency inverter

Featuring proven ISD vector control, the SK 180E is reported to be 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, it can autonomously manage simple drive applications and is suitable both for stand-alone variable frequency drives and synchronised operation with several units.

A typical example of the latter is distributed horizontal conveying applications requiring no positioning or encoder feedback, no special safety functions or braking resistors, and with motor power outputs from 0.25 to 2.2kW.

The SK 180E also contains all necessary functions for many fan and pump applications. Here, it can save up to 30% energy by automatic magnetisation adjustment under partial load.
