The MICROMASTER 440

The MICROMASTER 440s 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 75 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. A
special pulse-width modulation method with selectable Pulse frequency permits
quiet motor operation. Comprehensive protective functions provide excellent
inverter and motor protection.
The MICROMASTER 440 with its default factory settings is ideal for a large range
of simple motor control applications. The MICROMASTER 440 can also be used
for more advanced motor control applications via its comprehensive functionality.
The MICROMASTER 440 can be used in both 'stand-alone' applications as well as
being integrated into 'Automation Systems'.
