VF AS3

frequency inverter

Application
 The VF AS3 is a frequency inverter (rated motor power from 0.37kW – 315kW) for stepless speed control of asynchronous motors. Application in complex machines and systems, lifting and crane applications, textile machines, sequence controls. With the integrated web server and Ethernet interfaces, you can achieve high communication speeds in real time and are thus ready for the requirements of modern automation (IoT / Industry 4.0).
