Flexibility and dependability in a tried and true control

The Mark Ill Dynamatic® Controller consists of a single printed circuit board rated for 230/460 VAC, 1 phase, 60 Hz input. Optional output voltages are available depending on the controller selected from 10 available sizes. 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. Options are selected by plugging jumpers into the proper positions. Many other modifications are available as options. A variety of operator’s stations are available containing required elements for specific applications. This controller offers more available modifications than the Model 4000 or 4050 Controllers do.

The Mark Ill Controller is 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.
