MM430

The MICROMASTER 430 frequency converter is suitable for various variable speed drive applications. Its flexibility gives it an extremely wide range of applications. It is particularly suitable for use with industrial pumps and fans.
This frequency converter has user oriented performance and easy-to-use features. It has more inputs and outputs than MICROMASTER 420 (an optimized operator panel with manual and automatic switching), and has software adaptation capabilities.
design
MICROMASTER 430 frequency converter adopts modular design. The operator panel and communication module are easy to replace.
