DC Drives (25 to 7400 Amp)    Click here to go to the Emerson Website


DC SRC drives and motors remain common in industries such as metals, cranes, mining and printing. The current trend is to replace DC systems with new AC drives and motors to reduce maintenance overhead. This can, however, often be a significant task that requires the machinery to be taken out of service for an extended period while mechanical and electrical rework is completed. 

Utilizing existing DC motors and upgrading the DC drives is often the most attractive option. DC motors are usually well built and capable of offering many more years of service to help lower project costs and minimize disruption and risks. Control Techniques DC drives are now based on our industry-leading AC drive technology to deliver enhanced motor performance, reliability and system integration options. 

Mentor MP is a modern DC drive that is based on Control Techniques current AC drive technology
The Quantum MP is a complete drive package incorporating power fuses, DC Armature contactors and 120Vac controls
External field controller for DC motors with field currents up to 25A

 

 

 

Mentor II - Digital Variable Speed DC Drive


Quantum & Mentor DC Drive

Reliable, Flexible and Powerful DC Drives

5 to 1000 hp (75kW to 750kW)


25 A - 1850 A in Both Single and 4 Quadrant
The Mentor II provides a wide power range of fully programmable DC drives with a unified control interface. Mentor II is a reliable, flexible and powerful digital DC drive that is available both in non-regenerative and regenerative configurations. It accepts a wide range of supply voltage from 208 to 480 VAC. Mentor II drives rated at 525/660 VAC ratings may be special ordered.

It’s high-performance characteristics, fast coprocessors, dual encoder inputs, application and communications modules, and high-speed drive-to-drive communications capability place it in many applications requiring powerful motor control and coordination.

Simple stand-alone applications are quickly configured with a minimum of parameters.
  • Printing Presses
  • Heavy Moveable Structures
  • Lumber and Paper Milling
  • Paper Converting
  • Dual-turret winding
  • Plastic and Rubber Extrusion
  • Cranes, Hoists, and Cabling
  • Iron, Steel and Glassworks
  • Tilt Vessels, Coilers, Spoolers
  • Metal Fabrication and Wire drawing

Add the application module (MD29) to implement high performance drive systems with local intelligence. This intelligence can then be utilised to eliminate the master PLC by constructing a distributed control system, using the CTNet fieldbus with the System Programming Tool (SYPT). When integration with a master PLC system is required, a range of fieldbus adapters is available.
