AC Tech Enclosed Micro Drives:  The MC Series

AC Tech Enclosed Micro Drives: The MC Series

A variable frequency drive that speaks your language, the MC Series LCD display lets you know the status of the motor and machine in easy to read English. Drive set-up is especially straight forward and intuitive.
  From ¼ hp to 150 hp the MC Series is ready to install, wire and put into operation. Standard products are available in steel enclosures rated from NEMA 1 to stainless NEMA 4X (IP21 to IP65). The MC is available for all major power supplies from 120 volt single phase (which outputs 230 volt three phase to the motor) to 590 volt. The MC Series drive is the top selling drive for operation of 575 volt motors in Canada!

The MC Drives

MC Series drives are available in two versions:

• M1000 Series for standard applications
Designed for typical constant torque applications where motor speed is controlled from the drive keypad, a 0-10vdc or 4-20ma control signal, or a standard potentiometer. The M1000 series provides bi-directional control of the motor over a range of 0 to 120Hz. High speed operation up to 1000Hz is optional.

• M3000 Series for process control
Designed for processes where set-point control is required. The PID control algorithm in the M3000 Series is applicable on both constant and variable torque loads. Applications include fans, pumps, material feed conveyors, and rock crushers to name a few.

MC Series Options

Dynamic Braking:

For faster stopping or for improved speed control, dynamic brake control with external resistors can easily be added.

Remote Keypad:
Additional Form-C Relay:

Converts one of the open-collector outputs to a form-C Relay.

Metasys® communication protocol:

The MC3000 can support RS-485 serial communication for Johnson Controls Systems.
