Lenze AC Tech MC3000 NEMA 12 Industrial AC Drives

The choice when your process control demands fast acceleration and response. Designed expressly for use where the motor control is an integral part of a process, the MC3000 is rated for constant torque applications but can easily be configured for variable torque applications. Most process control drives are designed for variable torque applications where the motor is driving a centrifugal fan or pump. As such, these drives are limited to 110% current for overload situations such as acceleration or responding to a feedback change.

The MC3000 is a true Constant Torque drive rated for 180% of rated current for 30 seconds and 150% for one minute; this allows faster response to system changes and the ability to apply the MC3000 to non-centrifugal applications such as compressors, conveyors and other "constant torque" loads.

MC3000 drive features
