Mentor MP


If your application requires regeneration, an accurate speed control, a dynamic performance and a constant torque over a wide range of speeds, Mentor MP is the DC drive you need.

Mentor MP is designed for :
• improving reliability of the system and ensuring the sustainability of the DC installation,
• optimizing motor performance
• minimizing service times and downtime during the replacement of an older drive thanks to the electrical and mechanical compatibility

  • 5 to 1150 HP 3 inputs, 208/480 VAC
  • 15 to 1400 HP 3 inputs, 575 VAC
  • 300 to 1600 HP 3 inputs, 690 VAC
