The MICROMASTER 430

The MICROMASTER 430s are a range of 3AC-frequency inverters for controlling
the speed of three phase AC motors. The various models available range from the
7,5 kW input to the 90 kW input.
The MICROMASTER 430 is especially well suited for use with pumps and
ventilators when used with its factory set functions and settings.
The inverters are microprocessor-controlled and use state-of-the-art Insulated Gate
BipoIar Transistor (IGBT) technology. This makes them reliable and versatile. A
special pulse-width modulation method with selectable Pulse frequency permits
quiet motor operation. Comprehensive protective functions provide excellent
inverter and motor protection.
