  • 12 Volt power requirement makes this control ideal for portable, battery operated applications or applications when safety standards dictate a low operating voltage.
  • Speed Adjustment: can be controlled by an external potentiometer (included), the onboard MAX speed trim potentiometer, or a remote 0-5 VDC analog input signal. Speed range 30:1.
  • Unique Smart Reverse™ circuit provides quick reversing and prevents motor plugging.
  • Dynamic braking for quicker stops.
  • 12 pulse/revolution tach output provides indication of motor speed.
  • Logic output indicates control shutdown due to a motor overload.
  • Inherent closed loop system maintains a 2% maximum change in motor speed from 0-100% of rated load when operated at rated speed.
