The Micromaster 420 inverter is designed as an univesal inverter for 3-phase networks and optional field-bus connection. It has a modular design enabling the extensive range of 'standard' functions to be added to with a wide veriety of options. The operator panels and communications modules are designed to be simply pluged into the inverter without the need for tools.
Typical uses for the Micromaster 420 series
Conveyor systems; material transport; pumps; fans; and mechanical enginnering applications.
