1 Overview

1.1 The Nicotra Gebhardt EC-Controller

The EC-Controller EKE 05-00xx-5E-Ix is an inverter for controlling the speed of motor-
impeller-units with Brushless-DC motors. The inverter is DSP-controlled and uses modern
Insulated Gate Bipolar Transistor (IGBT) technology for electrical power conversion. This
makes them reliable and versatile. The EC-Controller provides inverter and motor overload
protection.
The EC-Controller can be used in both stand-alone applications as well as in large fan
systems using the integrated network interface for controlling and monitoring purposes.
