AC Tech AC Inverter Drives 

Stocked in Canadian and USA warehouses.

Produced in North America, AC Tech is stocked in Western Canada, Eastern Canada, and most of the continental USA.

MC Series -

Three Phase input or (Single Phase Input with de-rate)  /  Three Phase Output

 


 Constant torque / Constant HP drive

 

 

The MC Series drives are built in rugged steel enclosures that hold up to daily life on the factory floor. The easy to read 16 character LCD display above the drive keypad allows for easy and intuitive set up as well as daily operation.
  • 1/4 through 150HP (0.18 - 110kW)
  • Input voltages from 120V single phase (with voltage doubler) to 590VAC
  • NEMA Type 1, 12, 4 and 4X Enclosures

This constant horsepower drive can be set up for simple applications requiring ramped start, ramped stop and speed control to demanding applications that require PID set-point control and many other functions. The MC Series consists of the MC1000 and MC3000 models; most applications will use the MC1000 with a keypad that includes Start, Stop, up, down, forward/reverse, Program/Run, Auto/Manual and Enter buttons. 

For non-reversing applications that require independent switching of start and stop from local to remote and speed control from auto to manual, the MC3000 series keypad replaces the forward/reverse button with Local/Remote.

Technical documentation for the MC Series Drives, and all AC Tech brand drives, is available in the AC Tech Technical Library.
