Mentor MP

Mentor MP is a modern DC drive based on Control Techniques’ current AC drive technology. This means that Mentor MP inherits the system integration flexibility, such as:

• Three option module slots for automation control, I/O, feedback devices and communications

• Galvanic isolation (patent pending) between power and control protects the control circuits and other equipment connected to the drive from the high voltages on the power circuit. This feature is unique on DC drives
• Protection system against poor industrial power supplies and lightning strikes
• Integrated drive and motor protection for:
  • Over current
  • Over temperature
