We repair Mentor II drives to an extremely high standard.

These DC drives have an output range from 25A to 1850A. They are available in the single quadrant and four quadrant types.

Mentor II is the state-of-the-art, completely microprocessor-controlled DC variable industrial drive of choice. They are sold in a range of sizes with the same features:

  • Control
  • Monitoring
  • Protection
  • Serial communication

They come in either single-ended or four-quadrant designs. The single-ended kind of drive gives the client forward run operation only. Four-quadrant drives, on the other hand, are totally reversible.

Both kinds of drives offer full control of the motor speed and torque. If you choose the four- quadrant drive you have control in both directions of rotation.

The customer can select the operating parameters at either the keypad or the serial communications link which is known as the interface. A three-level security code system protects these parameter values.
