Application

The SIPLUS MICROMASTER 440 inverter can be used for a variety of variable-speed drive tasks. Its flexibility makes it suitable for a wide range of applications. This wide range includes cranes and hoisting gear, high-bay warehouses, machines for the food and beverages industry, packaging machines, etc.; i.e. applications that require frequency inverters with higher functionality and higher dynamic response than normal.

The inverter is especially characterized by its customer-oriented performance and ease-of-use. Its large range of line voltages enables it to be used all over the world.

Design

The SIPLUS MICROMASTER 440 inverter has a modular design. The operator panels and modules can be easily exchanged.
