International English 1.1 OVERVIEW The MICROMASTER 420 The MICROMASTER 420s are a range of frequency inverters for controlling the speed of three phase AC motors. The various models available range from the 120 W single phase input to the 11 kW three phase input. The inverters are microprocessor-controlled and use state-of-the-art Insulated Gate BipoIar Transistor (IGBT) technology. This makes them reliable and versatile.
