The Universal Inverter for Every Challenge

You need a frequency inverter which can be adapted to your individual requirements without any great effort?

No problem for our MICROMASTER 420 – the universal inverter for 3-phase networks and optional field-bus connection.

Thanks to its modular design, the extensive standard functions can be supplemented with a wide variety of options. And you do not even need tools, as the operator panels and the communications modules can be simply plugged in. Screwless control terminals – as with the rest of the family – make terminal connection child's play.  

Typical Uses

Conveyor systems, material transport, pumps, fans, mechanical engineering.
