MICROMASTER 420
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.

MICROMASTER 430
The Specialist for Pumps and Fans

Every task performed by a drive system involves its own specific requirements. There is therefore a demand for inverter solutions that can be easily and flexibly adapted to cope with the broadest variety of challenges. It is exactly this flexibility which characterizes our modular MICROMASTER 430. Specially for use with pumps and fans in industry, it performs a wide variety of tasks in similar applications as well. Compared to the MICROMASTER 420, it features greater power efficiency and has more inputs and outputs as well as an optimized operator panel with switch-over between manual and automatic modes of operation.

MICROMASTER 440
The Powerful All-rounder

Even in the world of drives, there are often forces which are difficult to control. Until the most powerful of our frequency inverters enters the field. The MICROMASTER 440 has been specially designed for those applications which require broader functionality and a greater dynamic response than is usually the case. The sophisticated vector control system ensures a uniformly high drive quality, even when sudden load changes occur. Fast response inputs and positioning deceleration ramps allow movement to target positions even without an encoder. Due to an integrated brake chopper, it works with outstanding precision, even during braking and short declaration ramps. All this is possible within a power range starting at 0.12 kW (0.16 HP) and going up to 250 kW (350 HP).
 
 Typical Uses
 Numerous applications in areas such as material handling systems, the textile industry, elevators, hoisting gear, mechanical engineering and the food, beverages and tobacco industries.
