A Legacy Control

If you have a Mark III Controller in place, it is a legacy piece. It can still be repaired, but we recommend that you consider upgrading to our EC-2000 control, which works universally with any eddy current equipment. For information about the EC-2000, please click here.

More about the Mark-III

The Mark Ill Dynamatic® Controller consists of a single printed circuit board rated for 230/460 VAC, 1 phase, 60 Hz input. It has the flexibility of 45, 90, 180 or 220 VDC coil voltages from 5.5 to 50 amps maximum and is available for use with a wide range of drives and brakes rated 1 through 5,000 horsepower.

An input transformer and power relay are standard features. The basic circuit board includes provisions for eight separate control functions: multiple cascading, linear acceleration, log accel/decel, current control, tachometer follower (Auto), 0.25% regulation, dancer position and DC tachometer feedback.

The Mark Ill Controller has been supplied as a panel-mounted controller or in a NEMA 1 enclosure. A power relay and input transformer are built in; so, a motor winding or loose input transformer are not required. Descriptions for the various sizes of Mark Ill Controllers, along with various input voltages, can be found in our Mark III Control Specifications brochure.
