Siemens Micromaster 440 is a wide range of industrial-type frequency inverters for 3-phased motors. In the series, you can find various models with the performance range from 120W to 200-250 kW (constant or variable torque, consequently).
Main specifications of the Micromaster 440 drives:
- Both stand-alone and automatic system suitability;
- IT-lines comparability;
- Fast cable connection and installation of inverters;
- Both digital and analogue inputs available;
- BICO technology implemented;
- Variable switching frequencies to provide quiet motor operation;
- Kinetic buffering;
- Set point input via various methods (analogue inputs, JOG function, preset frequencies).
Major benefits you get from frequency converters of Siemens Micromaster 440 series are full automatics of the inverter’s work and full-function operation with motors. In mm440 series, the IGBT technology is implemented. It also has some specific functions as kinetic buffering, slide compensation, combined braking for controlled stopping and brake block installed.
That type of frequency inverters is suitable for different types of motors and engines starting from the simplest ones due to the large automatic systems on the industrial factories and plants.
Siemens micromaster 440 was replaced by Sinamics g120/g120c models which have higher performance and efficiency.
