INTRODUCTION
The new Vari Speed S1000 is setting new standards in the field
of inexpensive DC motor controllers. The smallest member of the
Graham Transmissions, Inc. family includes features and
performance only before thought possible in larger, more
expensive units. By utilizing the latest in surface mount
component technology and manufacturing processes, this
controller is unsurpassed in performance and reliability.
Graham Transmissions, Inc. Vari Speed S1000 is a solid state
controller that converts single phase AC line power into an
adjustable DC power source. The unit has been designed to
control permanent magnet (PM), or shunt wound DC motors from
1/20 to 2HP. This NEMA Code K (2 SCR’s, 2 diodes, and a
freewheeling diode) converter ensures good form factor and
smooth, efficient motor operation. Because of the unit’s small
physical size and convenient mounting arrangement, it can be
located in panels with very limited space.
If you have any questions regarding the Vari Speed S1000,
please contact your local distributor, or consult the factory by
calling toll free 1-888-363-1313.
